NalinMFG I've seen screws, zip ties, tape, and self adhesive velcro all with reported success. It boils down to where you want to mount the crossover.
06-21-2013 12:12 PM
TJ_John I think zip ties will be fine. I've used them to mount my amp under the steering column and they hold without any issues.
06-21-2013 12:06 PM
freeskier I don't have components but my Infinity Kappas still have a small external crossovers that have screw terminals for hooking up the wire. They had slots in them for a zip tie so I zip tied them to a dash piece.
06-21-2013 11:48 AM
eboven I screwed them in with self-tapping screws. I tried to get good pics of the crossover locations, but I'm not sure if you can see their exact locations well or not. Getting a drill up there wasn't as bad as I expected, though I do have quite a bit of experience with tight spaces because of my job... zip ties are perfectly acceptable so long as they are tight and the crossovers don't slip around once cinched down.
06-20-2013 10:19 PM
VTBalla34 I have a stupid question and I don't even know if you check this thread anymore (good threat btw) but did you mount the crossovers with screws? Or zipties? Or just let them rest on something? I have the Nalin kit and install is going smoothly except for me not knowing what to use to mount the crossover.

I have big monkey hands and it would seem very difficult to get up in there there with a drill. Any advice?

eboven Yep, Pioneer TS-D1320C: D-Series 5.25" component speakers. I would certainly recommend them paired with the Nalin brackets - the sound is not even comparable to the stock setup...

eboven The crossovers for the rear soundbar speakers are under my radio, behind the climate controls - there is quite a bit of room there. I ran all new speaker wires, so they run from the amp under the dash to the crossovers behind the HVAC panel and then back and up to the soundbar.
02-15-2013 04:18 PM
Dan216 I pretty much know nothing about audio systems, but am looking to put one in myself. Where do you hide the crossovers that come from the soundbar?
01-05-2013 12:37 AM
RayW That is my next planned step with my front speakers, also. I will probably pick up some better coax speaks for the sound bar and figured I would piggyback the baffles on the order.

As far as being an audiophile, I guess I qualify with my home system but on the road I've always been a "good enough" kind of guy. As long as I can hear the music and bob my head I'm in good shape. My stock setup was about 3 steps below good enough.
01-04-2013 02:51 PM
bobthetj03 I did the same thing too. It did make a noticable improvement.
01-04-2013 10:34 AM
eboven RayW:
It's cool to see another audiophile on the forums, I look forward to your future contributions and input here; seems like you know your stuff! I would say that the tweeters on the dash were certainly louder, but the imaging was off. Since I have switched to the Nalin tweeter mounts, the imaging is MUCH better, and the frequencies mesh together better.

I removed most of the stuffing around the woofers, and installed foam baffles sandwiched between the Nalin plates and the woofers up front. This made a notable improvement in midbass, but I get a bit of rattle from my passenger side air-vent now with certain frequencies. I usually listen to my stereo with the fader all the way to the front now, and the bass is honestly almost as good as with the woofers in the soundbar working... the imaging is definitely better too.
01-02-2013 06:33 PM
freeskier Great thread. Great to hear about the Nalin tweeter brackets, I installed my audio set up before they came out so I went with coax speakers in the front. I'm thinking about redoing my sound system again this summer, with the tweeters in the stock location they are VERY muffled.
01-01-2013 10:37 PM
dtaz04 I am looking to completely redo my system. I want to put a sub in w/o losing the little space I have
01-01-2013 01:31 AM
RayW Sure thing. Personally, all I've done so far to my Jeep (only had the TJ for a month) is to use the Nalin bracket to mount some 5 1/4" Vifa coax speakers that I had leftover from another project and drop in an Alpine head unit. Incidentally, if someone worked out a way to isolate the front of the dash speakers from the back (Jeep tried with those foam baffle thingies on the 4x6) it would really increase the bass up front. I haven't figured out an easy way to do it yet. The stuffing that eboven used is a good start.

I'm currently working out a micro-sub setup to add a little bottom end using the space between the seat base and the rocker panel. It won't be a thumper but should help round out things a little. If I get it worked out I'll start a new thread. I don't want to hijack this one anymore than has already happened.

And in an attempt to un-hijack...First rate install, eboven! I love the amp mount location.
01-01-2013 01:09 AM
dtaz04 RayW do you want to design my speaker set up for me? Lol

Putting the tweeter further from the listener means that path length differences between left and right channels will be minimized. That should improve imaging and soundstage provided, as you said above, that the distance between tweeter and woofer is adequately small (less than 1/2 wavelength at crossover frequency for real coherence). Dash mounting the tweeter puts the near side driver much, much closer to the listener than the other side which will cause delays that are easily detected by most listeners. Compounding the problem is the fact that the woofers are farther away with less path length difference so you get a disconnect in the image between the woofer/mid and the tweeter.

Having said all that, if you put your tweeters up on the dash and it sounds good to you, turn it up and drive on. Most acoustic minutia like that get swamped in any automobile and even more so in a Jeep so at the end of the day it just comes down to what sounds good to you.

p.s. I design speakers for a living. I can provide credentials if needed.

I dont have a garage so my whole install is "Shade tree install" which is why it looks like it was thrown together in the matter of a few minutes. but heres a pic of the sub in the seat.

I fiberglassed the crap out of the box so it would hold up to the water. I rarely have the doors and full top on so it gets wet easily, the amps are raised off the ground so no water gets to them. Maybe one day Ill get in there and clean up the wires, make a baffle for the seat, and get the whole thing cleaned up but thats gonna have to wait for now.

One bad thing I can say about putting the sub in the seat is that it makes the seat pretty uncomfortable for an adult due to the lack of padding in there and that you are sitting up higher so theres alot less headroom.
Nice! I am currently using my Alpine Type R 12" in a large ported box whenever I have the back seat up right now. It sounds amazing, but it takes up quite a bit of room and there is no way it would fit if I needed room for any more than one other person. I've had the sub on craigslist, but everyone just keeps low-balling me, so I've held onto it; once it sells, I plan to get a 10" CVT and build it into the back seat like you did. I bet that 12" sounds pretty good!

How much padding did you have to take out? I've seen some people leave a bit more than usual and then "stuff" the box into place to keep the seat more comfortable. I have friends riding in the back seat from time to time, so I am planning to make the box as shallow as possible to allow for more padding; we will see how it goes once I get it all apart! You said the rear seat lost some headroom too; I saw you have the Rampage frameless top. I plan to get the same top this spring; how bad is it? I would imagine that with my current hardtop this would be less of a problem.

I work as a mobile electronics installer for a major electronics retailer as well... did you move to another company, or out of the industry all together?

dtaz04 will you send me a pm of all the stuff you bought and the price. i am looking to do the same thing to my jeep
12-08-2012 11:17 PM
sjones26573 Glad it worked for you! I actually won a set of Nalin dash and tweeter mounts after my post here so now I'm going to pick up some Polk speakers for the dash and move my Kickers to the pods to get rid of my last stock speakers. Having you satisfied with the setup makes me even more anxious to get mine installed.
12-08-2012 06:52 PM
eboven Well, thanks to Andrew Nalin, I installed the Nalin MFG component plates earlier this week. I was very impressed with the plates overall - nice clean cuts and they fit perfectly. The supplied hardware for the 5.25" woofer was very nice, and there were no gaps around the woofer at all. The tweeter mounts lined up perfectly with the stock door strap post's bolts, and my Pioneer tweeters fit perfectly in place with no gaps.
If you plan to replace your front speakers at all, you need to buy plates anyway, even to install a crappy 4x6" aftermarket speaker; car audio shops usually charge 20-25 bucks for them. There is no reason not to just buy the Nalin plates and get them shipped to you - it will probably end up being cheaper and will allow you to install a better sounding 5.25" speaker in the dash with no modifications. I almost feel stupid for not buying them in the first place and making my "custom" plates.

I listened to the system for about 4 days of driving to work and back - I have an hour drive each way, so I got plenty of listening in, trust me! I listen to every kind of music, from Pink Floyd to Skrillex to Avenged Sevenfold... I would say that overall, the sound was certainly improved with the tweeters mounted low where the Nalin mounts put them. The sound is more smooth, with less of an ear piercing effect. The soundstage is still great for a Jeep, so I have to admit I was proven wrong about tweeter placement.

I did notice a couple things that deserved my attention. First, with the tweeters being mounted so low, they obviously weren't as loud as they were on the dash. I first removed the 3db attenuation on the component set's crossovers. This made it a bit better, but the midrange still wanted to overpower the high frequencies. I set my Alpine stereo's fader to the front a bit, and that really made the difference.
Second, since the tweeters were not as piercing anymore, I could turn the volume up a few more notches before my ears really hated me. This made me notice some rattling from front midrange speakers at certain frequencies. I took the covers off and applied pressure on the plates in different places and was able to make the rattling stop, so I knew it wasn't the speakers themselves, rather just the metal plates rattling on the metal bars. I grabbed some dynamat scraps I had left over from my previous car's 6x9" install. Dynamat is an excellent sound deadener, it virtually eliminates panel distortion and rattling when applied properly. I covered the front of the woofer plates and mounting bars with the dynamat, reinstalled, and voila, no more rattle!

I ordered some 5.25" foam baffles, but they didn't arrive in time for the weekend. Just for fun, I figured I would give polyfill a try. It honestly made a surprising difference for the front midrange; I have mine on a 100htz highpass filter, but the mids are much more pronounced after I installed the polyfill. I also stuffed the soundbar; the 6.5" woofers I have in there definitely have noticeably more punch.

On to some pics!

Nalin woofer plates - taking the rattle out with some Dynamat. A scrap 6x9 cutout works perfectly here.




I also Dynamatted the bars that the speaker plates screw into to keep them from rattling on the dash mounts. I filled the cavity with polyfill to slow down the low frequencies and improve midbass.


The only picture I got of the woofer and tweeter mounted before my camera died on me!

eboven Just want to put my $.02 in here. SirGCal does know what he is talking about most of the time. Being a mobile audio professional myself, I can tell you that most of the things I have read from him are true and make sense. His plans for a box in the rear seat are what I plan to model mine after, and looking through some of his work, he does seem pretty legit. That being said, I have seen some things that simply didn't make sense posted by him.

His description of why you shouldn't put subs into the soundbar is because it's too turbulent up there with the top off, which will damage the subs. This just doesn't make sense to me. I understand that wind will be whipping around up there, but Jeep put speakers there in the first place. If you have a 6.5" full range dual cone speaker up there, it will be effected by the wind the same as a 6.5" low range woofer. One could even argue that the stronger motor on the woofer would resist atmospheric pressure more, meaning a sub would be a better choice up there than the factory speakers. Add in a properly designed crossover network, and you have a great spot to mount some good midrange woofers to compliment the sub that's going in the back seat. I don't know of any speaker out there that won't distort in the soundbar when the Jeep's traveling down the highway at 60mph; I also don't know many people with hearing good enough to hear said distortion.

Ibuildembig IMO the best thing you could do is make them user adjustable. The perfect location for a tweeter is going to differ with each end user because of their size and how the sit in the vehicle. Ultimate midrange placement would be in the kickpanels with the driver facing oposing sides (ie, the passenger one will be aimed at the drivers right ear and the drivers side would be aimed at the passengers left ear) What everyone tries to achieve in the audio world is a center stage and imaging. Its near impossible in a jeep to have imaging (unless a guy wanted to hack his dash up and install a set of waveguides firing up) There are several of us on here that do this for a living and have competed for a very long time. I'm sure that they along with myself would be happy to help you out with product ideas and questions

Being the moderator for a Jeep electronics forum, running a Jeep audio how-to site, and previously owning an audio shop rate high enough in my book to merit a little credibility. I'm sorry that you feel that way towards him.

You're not going to find a lot of threads with information regarding tweeter placement in Jeeps. I try to remain actively involved in discussions that pertain to products that I sell. If there's a way to make something better - that's what I'm going to do.

I'll butt heads and defend my ideas/thoughts/opinions, but ultimately I'm here to learn from those who do consider themselves to be "experts". Right now I am convinced that mounting tweeters under the dash is the way to go.

Prove me wrong

bobthetj03 Getting proper power to the speakers makes a big difference. I like where you're going with the sound system. Don't count out the center console for a sub if you like to keep your storage. Dissadvantage about the sub in the back seat is you lose your bass if you need to take your back seat out. IMO, components are a waste of $$ in a TJ.
11-21-2012 08:00 PM
BlueRidgeYJ Yet another thing Jeeps make you comprimise on. Best if you could dash mount em and drive from the back seat. Just sayin', lmao.

Still way better than not driving a Jeep
