Smile Two 10's or One 12..?

Okay so I got these crazy awesome deals on Best Buy's deal of the day and got two 10" subs by polk audio for $30 each (retail $90). Right now I have just one installed in my Jeep and it sounds pretty good but I'm always looking for the best option. So anyways, then last week I went and bought another one of their subs. This time it was one 12" pioneer that I got it for $40 (retail $120). I have no problem selling one or the other but I would like to have it set up the best I can. Any suggestions would be great!

A single 10 or 12 setup correctly is more than enough for a Jeep. Depends on what sound you like and what type of music you listen to.

Most likely you will not be able to build a box large enough to make those speakers perform properly unless you take out the back seat. Figure out how much volume you will need for those speakers to perform properly and then figure out where you will put the box. Remember that a ported box needs to be larger than a sealed box, but a sealed box needs a more powerful amp.

Welp I knew none of that info right there...personally I have one 10" in a ported box ( just recently discovered :wink: ) and it is deffinitly sufficently loud...I'm talking rattling change in my cupholders loud or mirrors shaking loud. It even makes my muffler heatshield vibrate. So maybe that sound be the way to go.

I have a custom sealed box for my two 4 ohm 8" kicker subs. Each speaker requires at a minimum of .5 cubic feet of space. My box behind the back seat has 1 cubic foot of volume and really could not be larger.

I have two 12" Alpine Type S in my TJ in a custom ported box i built myself. and they absolutely PUMP!! I ended up blowing the previous two 12" Pioneers. Depending on where you put them you shouldnt have any clearance issues as long as you dont mind giving up luggage space like i did. i went for two 12s cause when you take the roof off more base escapes and its quieter. So with the 12s it still pumps loud with the roof off.

also what kind of amp are you currently running, you could need to upgrade that as well to push 2 12's. Amp's are expensive.

I dont really see the need to use 2 subs in pretty much any vehicle. If you want more bass, use a better sub. A single 12w7 with 1000w pumps out serious bass.

what he said.

that being said i was always a sucker for symmetry.. in my cars i always went with two subs. but with the lack of space in a jeep id stick with one if i had to put a sub in it

Without modification to the backseat you can fit two 10s down firing, two 12s down firing (a little harder), or a 10 in a ported box. That's about it assuming that you don't want to mess with shallow mounts. If you take the top off a lot you should down fire the two 10s since you already have those, just know that a box for this may be a little pricey.

I have an 8" bazooka tube in the back of my TJ and that is enough for me. In my 02 Mercury Cougar I had two alpine type r's with a 1000w RMS alpine v-power amp. That was bumping! The bazooka tube is probably less than one of the type r's in my cougar but seems adequate for me in the jeep. The decision is really up to you on how much space you want to give up in the back. I keep my back seat in because I always like to be prepared to have extra people in the car, thus bazooka tube is perfect behind the seat. If you want to have your brain vibrate from the bass, go with two 10"s and take the back seat out. Just remember that when you pull up to the stop light with your bass shaking the car next to you, people notice and might follow you to steal your equipment. And its pretty easy to steal stuff out of a jeep.

I have a 2x10 box in my chevy, and I don't see that thing fitting under the seat and maintaining the same volume, let alone fitting a 2x12 box. My box was a downfire setup, and it still took up pretty much all the space under the rear seat. Extended cab by the way, I am pretty sure the space under a TJ back seat is shorter.

I could see a single 10 box downfire, maybe even a single 12, it you made the box a really shallow design.

You could easily fit a box behind the back seat though if you don't care about hiding it or having any storage space whatsoever left over. I don't know what you use your jeep for, so that is all you.

I've got two 10s behind my back seat in a probox and have the amp mounted under the seat and about .50 inches off the floor just in case water decided to come in. Looks and sounds great but have no room behind the seat anymore.

How hard is it to remove that box?

I'm looking for something I can disconnect, unbolt, pull out quickly.

When I go to the range my shooting cart barely fits as it is, with the back seat removed already.

Obviously not too easy to remove so a random passer by cannot just snag it and walk away.

I've been thinking about installing one of these in a modified sound bar overhead.

All you've got to do is pull box back as far as it can go, flip seat up, turn box to each side to remove wires which is just two push buttons on each side, then straighten the box up an pick up and pull out. In all of about 3 minutes.

And it's lined with a bedliner so if it gets wet it's alright and it can be roughed up a tad bit. I paid about 160 or 180 for it. I love it. It's called a Jeep Jammer ProBox by Probox Rocks.

For a vehicle with the small interior volume of a Wrangler, isn't even a single 8" subwoofer more than enough? Or is this more about what bigger subwoofers can do outside of the Jeep? Heck I have a pair of big Boston Acoustic speakers at home with two 8" woofers in each & they can produce more bass than my living room can handle.

I'd choose 2 10's over 2 12's because I like more punch. I'd choose a wall of 10's over a wall of 12's any day of the week. Love that crisp punch. Especially since I don't listen to rap.

It depends on what you like. I have 3 12s in my bedroom, 2 12s in my office, and 1 12 and 4 8s in my living room, but this is too much bass.

properly setup 12s hit just as tight at 10s, but can also go to lower hz. The only time I would ever use a 10 over a 12 is if I couldn't fit a 12.

Is Crossfire Audio still around? A while ago they had a 10" BMF (stands for what you think it does). It had the output of 2 of their normal 10"s, but drawback was it also required almost as big an enclosure as 2 normal 10"s. That thing sounded amazing and you could drive it with a class D for less power draw.

I went by a stereo place today and the guy who worked there listened to my one 10" and agreed that it sounded really good. I think I might just sell the extra subs I got and buy new tweeters and such.. I'll post a video on youtube sometime soon and upload it here for y'all to get an idea.

jwcom93, those are new shallow mount jl audio. i think they are 13. about $500 a piece and dont think you can mount them in soundbar. I do think one would work great in a seat install application. I put a single jl audio 10 w6 in my sons jeep and it absolutely PUMPS!

Yup. With only 2.5" of mounting depth, I think I could fab up a custom sound bar with a 13 in it! They sure as hell wont fit in the stock sound bar!

Even if you could fit them in the soundbar, they wouldn't sound as good as they could in a good box. Subs need some airspace. That's why I am hesitant to just replace the one in the console, it still won't sound right. I still like a 2x10 down fire setup, worked great in my truck and the interior volume is about the same as my TJ.

Something like those shallow mount JL's would let me build a little smaller box though, but I can't do $500 a speaker. Does anybody else make that style of sub?

That one only needs 0.8cf! or roughly 1'x4'x2.5" Not sure if 4' would fit, but it wouldn't be too hard to get a box with only 0.8cf of air space.
