Aftermarket Stereo in the 7 Speaker setup

OK,

So I've just installed a new Alpine deck in my TJ after the Sony I was using died.

The Sony (and the Alpine before it) worked wonderfully with the speakers, specifically the sub.

But since installing the new deck (Alpine CTE-148BT), it seems that VERY little sound is coming from the sub. Some is ... I can barely feel the movement when the stereo is turned up well enough.

Have I missed something simple in the install? I wired color to color in the harness -- just as I've done in the past.

I've checked the fuse for the sub. I've not yet taken the sub out to check everything there, but nothing should have changed in the enclosure.

I've also checked that all four quadrants of the speakers -- everything seems to be coming out correctly.

Maybe you blew out the sub. This is a normal occurrence. Especially with the 6.5 console sub. Try turning up the bass and see if the sub starts to rattle. If it does, it is a good indication that the sub is blown.

I don't have the factory sub but aftermarket everything. If your sub has its own pre out on the head unit maybe your new unit has a gain setting for the sub. My pioneer does. I can turn the sub down all the way or up louder then I want it. It's not a knob or anything it's buried in the audio settings. If I didn't know about it I would be having a very similar problem.

Yeah, I'm using the stock sub/amp, which is wired through the wiring harness and not the pre-amps.

No rattle at all. I've blown the sub before, and am familiar with the sound.

I DO have an extra backup 6.5 sub, since they were so cheap at the time. I'll probably pull apart the console to check next weekend (won't have time until then), but I'm 90% sure it's not that.

Please keep us advised on what you find out. I've had a similar problem with a new head unit and factory sub set up. Mine is different in that the sub is intermittent (mostly doesn't work), and I get crackling through it when I hit the brake or activate other electrical components.

And this only happens in cold weather...I figure I have a short somewhere, but I can't find it.

Sorry, not meant to hijack, but I bet the problems are somewhat related.

Honestly, I got some sound out of it coming back from an appointment just now, but it felt like it was pushing mids, not bass. But I switch from a singer/songwriter track to something like Tupac, and it's evident that something is not right.

did you wire the power antenna lead on the aftermarket deck to the sub amp wire (which properly powers it)... maybe the wiring changed from one deck to the other...

As indicated above, you have to connect the power trigger for the sub amp. It's usually a blue wire from the head unit and on some it is the antenna wire.

Yeah, this was an original problem, but something I resolved early on (I know the difference, just wasn't thinking right).

But if that were still the problem, the sub would work when on the tuner, right? It wasn't.

That being said, the whole thing started working yesterday. Not 100% sure what the problem was ... probably got a lose connection somewhere.

Hey Dorv,

I just installed the Alpine 148BT. I am loving mine so far for the most part. I am having potentially the same issue though. My sub preouts are powering a Pioneer amp and 2 8" subs. I have them sitting in the trunk free-air though so maybe that's why I am getting very little sound from them even though they are designed to handle free air.

Let me know if you find any solution to your issue.

Also, have you by chance used the Tune-It phone/tablet app to adjust your Alpine? I am trying to figure out how to get the app to pick up the HU and vice versa.

I can't speak to any issues you might be having with your pre-amps (other than you'd need to go through the settings and make sure everything is turned on and adjusted for your sub), but I can speak to Tune-It.

It's a pain in the ass. There's a setting w/in the HU that allows you to communicate via BT or USB. Once that's set,you have to power of the HU before the new setting takes effect. As best I can tell, USB works for iOS and Bt works for Android. At least for USB, you need to have the app active before plugging in the phone.

OK, when I said "working" I didn't say "working right."

There's still VERY little output from the sub, but if I slide the balance either all the way to the left or right, the sub kicks in wonderfully.

Really, really pissing me off.

Ok when you have it to the left or right it is full output. The factory sub amp is wired in from the 4 speaker inputs and when you have the L/R speakers feeding, there is low output. It sounds like you have the L/R wired out of phase with the new head unit. The main speakers will sound poor and have poor bass output also when out of phase.

Boom. There it is. I'd reversed the wiring on one of the rear speakers.

Of course, I had to pay Best Buy $30 to figure it out for me, but worth it in the end.

(Not that I didn't take the advice here, I just thought better of myself and my ability to determine the difference between purple and purple/black

Glad you got it. I've always hooked speakers up by sound on by one. You can always tell the difference when it is out of phase. Try it back an forth. When it is out of phase it will sound muddy and the bass will drop.
