Infinity Subwoofer not working with Kicker/Nitro amplifier?
 
So when I bought my 2011 JKU with Infinity option, the day before I took delivery the dealer realized the radio was not working and troubleshot it to the stock Infinity amp popping fuses whenever power was applied. So they ordered a new amp to replace it. I didn't want to keep waiting so I took the Jeep. After 4 weeks of waiting and being told "it's in work" and after lots of research in this forum, I decided to just order the Kicker (77Kick46) amp and some Kappa 6.5" for the soundbar because it would get here faster and everyone seems to recommend it anyway.

Keep in mind at this point I still have never heard a 2011 Infinity system in a jeep. So I installed the Kicker amp and the system worked like a champ. I thought it was pretty good overall but there was hardly any bass and figured this must be what everyone was talking about. The next day I installed the Kappa's and it sounded a little better but there was still no real bass in the sound. It's very clear and loud but lacks all bass. I went back to subwoofer and its putting out a tiny and I mean tiny amount of bass, to the point of it was pointless to even be there.

About a week later the replacement Infinity amp showed up and it's just been in the box. I was going to put it on eBay or something, but I figured since the one in my Jeep was bad from the factory, I would plug the new one in just to check that it works..... I was actually shocked at how much BASS was being put out now by the Infinity amp. It was exactly the amount of bass that I was expecting the first time. But the sound coming from the front and soundbar inst as clear as it is with the Kicker.

So my question is, does the Kicker/Nitro Amp even work with the Infinity subwoofer. If it does, why would the subwoofer put out tons of bass (for a stock system) with the Infinity amp and the so called Kicker upgrade not put out any bass? The only thing I could think of is that the Kicker amp doesn't put out sub power because if you had a Kicker system you would have the self-amplified Kicker subwoofer. But if that's so, how come out of the thousands of threads in the forum related to upgrading to a Kicker/Nitro amp no one ever mentions that you will lose use of your Infinity sub?

I need help figuring this out. I am overseas, so I donít have the luxury of running around to electronics stores buying upgrades and shipping things like heavy subwoofers and boxes gets expensive fast.

Sounds like the infinity sub is simply engineered to work optimally with the infinity amp. Same reason bose speakers will work best with the bose receiver that they're sold with.

As far as upgrading, replace everything or nothing for best results IMO.

aaron97 01-05-2012 06:42 PM

I'm starting to wonder if they sent me the wrong amp. I ordered the 77Kick46, but if they sent me the 77Kick33 that is only 5-channel and not 8-channel, this might be the cause.

Well, i checked and its definitely the 77Kick46 like I installed.

seanpholman 01-22-2012 05:08 PM

Did the 77KICK46 open up you soundbar speakers? If it does than it is worth it for me.

Nope. The soundbar still doesnt get full range. Slightly better, but not by much.

On another note, i installed a Kicker CVR8 subwoofer in place of the stock infinity woofer and again, no difference. But today i am installing a Rockford Fosgate PBR300X1 (300 rms x 1 @ 1ohm) to power the subwoofer.

seanpholman 02-07-2012 04:19 PM

I'd like to see some pics and know more about how you like the upgrade. Honestly, I'd like to do the 77KICK10s, 77KICK46 amp, then run a small amp to boost an aftermarket sub. I don't need much, just a little improvement.

--Sean

aaron97 02-11-2012 06:28 AM

Ok, so the weather here has been in the 5-20'F range for a while now and i dont have a garage to work in. So i still haven't been able to get to the amp install. I did run the power & ground wires for it, but by then i thought i was going to freeze to death and decided the rest will have to wait for a warmer day. Its supposed to be in the 30's tomorrow, so as long as there inst any wind, i might actually get a chance to work on it some.

But in the meantime, here are some pictures.

Here is a picture of the Rockford Fosgate PBR300X1 amp.. I just put the iPod Nano in there so that you can see how small the amp is.
http://img.photobucket.com/albums/v2...p/20419600.jpg

And a few pictures of the power and ground wires. I am going to make a bracket for the PBR300x1, so that it can sit on top of the stock amp, but with a little gap so that they both still get good airflow for proper cooling.

From the battery to that big harness that runs across the engine compartment.
http://img.photobucket.com/albums/v2...p/IMG_0306.jpg

Just showing how its almost 99% hidden. I went back after this and add zip-ties to make sure it stays up behind that harness.
http://img.photobucket.com/albums/v2...p/IMG_0301.jpg

There was a great pass-thru hole already built in. Not sure what it was for, but wasn't used for anything on my JKU.
http://img.photobucket.com/albums/v2...p/IMG_0302.jpg

Here is where it comes through to the inside, to the left of the brake pedal and completely out of the way. I think it might be used for the clutch if it were a manual trans.
http://img.photobucket.com/albums/v2...p/IMG_0303.jpg

This is just showing it passed through. I have the ground hooked up here, but i will see how that works later. The amp has an all-in-one connector for the Pwr/Grnd/Rem to make the install easier
http://img.photobucket.com/albums/v2...p/IMG_0305.jpg

That's all the pictures of this i have. I will try to snap some shots of the bracket as i make it and the install of that as well. Then i will let yall know how it sounds.

seanpholman 02-12-2012 12:16 AM

Just as a side note, I found out that the 77KICK46 is the wrong amp part number for '11+ JKs. Maybe this was the issue of why the sub wasn't working? The correct part number is 77KCK056.

Love the install and write up, good stuff.

Just starting to educate myself re: speaker/amp/head unit upgraded, do please excuse my ignorance and newb questions.

I was under the impression that the stock Infiniti sub was 6.5". Assuming that's correct, I have two questions: 1) how did you put an 8" sub into the stock box, and 2) I've been told that aftermarket subs MUST have a box made for them. Does the stock box work well for the aftermarket sub you used?

The stock infinity sub is an 8". It actually measured 8.8" total, which was one reason for needing to make an adaptor ring. The other reason for the adaptor rings is that you have to space the new sub out a little to clear the back side of the sub enclosure, and it give a better way of screwing the new sub down.

As for size, i read somewhere on here what the stock enclosure was and it was only .1 off from what was recommended for the Kicker sub. Stuffing poly-fil in there should help offset this.

Cool, thanks. Don't know where I got the idea that the sub was 6.5". That sounded wrong to me. Thanks for clearing that up for me.

You have any links to more info on that 77KCK056? I've tried searching for it but cant find anything on it and Kicker's site hasn't been updated since 2010.

No, I got the part number straight from a contact at Mopar and am attempting to verify through Kicker. I will post when I have the part in hand.

aaron97 02-13-2012 02:33 PM

It was 51 degrees yesterday, so i decided to play with the amps. I took hooked the stock Infinity amp up and it actually sounded okay. There was more bass now with the Infinity amp and Kicker sub. With the Kicker Amp and sub, there is no bass. Then i temp installed the Rockford Fosgate amp, wired into the front outputs off the Kicker Amp and i was amazed. Its perfect. All the bass a normal person could want. I have the gain at about 50% on the amp and its still enough to shake the jeep. Now i just need to get some dynamat because that sub sounds like it destroy the enclosure. You can hear all of the plastic back there rattling on really bassy sounds.

SO today i am going to work on mounting the RF amp. Then i will get some pics.

aaron97 02-14-2012 03:22 AM

Rockford Fosgate PBR300X1
 
Well, i finally got around to installing it all... and i must say, Awesome! This little amp and 8" really pack a punch. I only have the gain set about 50% and it hits pretty hard. Not over the top, but enough that people on the side of the road turn to look. Out of everything i have done, this by far was the best improvement. I did plug the Infinity amp in just so that i could compare and its no comparison at all. The Kicker's mids and highs are much cleaner and louder then the Infinity. But if you just wanted more bass and you currently like the Infinity, then upgrade the sub would be fine, just as long as you never here how much better it will sound with the Kicker.

I was going to make a bracket, but i took the simple route. I pulled the cover off and strategically placed holes in places that i could put a screw without it being close to any of the components inside the stock amp. I probably should have took a picture of the inside but i forgot. Also, initially i thought that i needed to place the amp on the passenger side of the stock amp, but after a test fix, turns out the brake light switch was in the way, so i had to move the RF amp to the drivers side of the stock amp.

http://img.photobucket.com/albums/v2...p/IMG_0352.jpg
http://img.photobucket.com/albums/v2...p/IMG_0354.jpg

As you can see here, when placed on the side of the stock amp, closest to the door, it clears the brake-light switch. If you look hard, you can see the small piece of high-temp tape that used to cover the open hole from my first mounting attempt. Since i had to take all of this back apart to relocate the new holes, i took this chance to swap out my stub-washer-nut setup for a screw, to make more room for the connectors.

Nice little setup. My Kicker stuff should be here by the end of the week, so I am interested to hear how the stock sub works with the "correct" amp. Glad I don't live anywhere near you to hear your setup. :)

I'd definitely like to know if that Kicker you found works right. Being a Kicker, it should still have the same increase in quality but actually have the subwoofer working as well. And if that's is the case, then we need to spread the word so that all the other 2011+ guys dont keep wasting money on the 77KICK46.

Yeah, that's the plan. I will be doing the install for a magazine article so word should get out quick. I am fine with the stock sub, I just want better speakers and a freed up sound bar.

So does it unrestrict the sound bar?

Haven't had a chance to install it yet. Probably this week.

Have you had a chance to hook it up yet and see if it opens up the soundbar?

Rear speakers are in, I am doing fronts and amp tomorrow.

Looking forward to hearing more about this install. I replaced my sound bar with the Kicker 77kick10 as well. Picked up an Alpine PDX-5 amp though to power the stuff rather than the Kicker amp. Will be using the AudioControl 6i to hopefully get full sound to the stuff.

seanpholman 03-01-2012 05:14 PM

Got the speakers in amp in today and it sounds nice. You can tell that there isn't any more power. It certainly doesn't *THUMP*, but it sounds crisper and brighter and the sound bar is definitely improved. I don't know that I would call it opened up 100-percent, but I can now hear the music with my seat reclined or in the back seat. There is definitely power to the factory subwoofer, but it is still very anemic. Bass kind dribbles out of it without any hard hits.

I still have the Kicker sub to do, but that will have to wait for now.

Thanks for the update. Sounds like it may be a good thing I did not go with the kicker amp upgrade. Of course I will have to see how it all goes once I get to install everything. Amazon sent me the wrong wiring kit so I gotta send it back and wait for the right one to come now. Argh!

seanpholman 03-01-2012 09:26 PM

A couple more thoughts. Because of the location of the amp connections, it is really easy to swap back and forth to get an idea of the differences back-to-back. I listened to some Reel Big Fish Sell Out (ska, lots of highs and lows together), Pearl Jam Elderly Woman Behind The Counter... (good rock), and Some Dr. Dre and Snoop Dog Ain't Nuthin' But A G Thang Baby (Gangsta' Rap for vibrations and subwoofer action) to get a feel for the differences. Here are my observations:

The factory amp is actually fairly good, puts out lots of bass to the sub and front stage, but cuts power to the sound bar. I actually thought I liked it better at first blush, until I got deeper in the music. Swapping back to the Kicker amp, the songs were much less bassy, but a lot clearer and brighter. And while the sound bar is opened up quite a bit, the factory subwoofer has way less output. My thinking is that Kicker is relying on the whole Stage 3 package together and by doing such, is pulling base from the speakers in anticipation that a proper 10-inch sub with the 200W amp being added will handle those duties. Possibly this frees up the speakers to reproduce mids and highs more accurately. This is just a guess from a guy who loves music, but is admittedly not an audiophile.

I am anticipating some serious bass with the 10-inch Kicker sub installed. Probably next week.

I did the same thing a while ago with the 77KICK46 amp. The stock Infinity amp had a lot of bass but the Kicker had a much cleaner sound but no bass. That's why I ended up swapping to an aftermarket Kicker 8" and adding the Rockford Fosgate 300x1 amp.

Now, i am curious though, with your new Kicker Amp, if you use the audio controls on your radio to turn all the sound full to rear, does it play full sound out of the sound bar or does it sound like crap?
