Help!!!! Horrible Install!!
Ok, I just got back from the shop thats installing my subwoofers and I couldnt be any more upset. Im running two ten inch subs with a class D amp. The car is a C6 with bose system and Nav headunit. Here are the problems:
1. I cant control the bass with the headunit. I have never heard of this?! The guy wants me to use some cheap/ghetto looking **** that came with the amp and either drill it into the car or leave it under the seat. What can I do to get the headunit to control the bass??
2. The bass volume wont go low enough. Even at minimum with the **** thing, I cant get it to get low enough so as not to really notice it.
3. The bose system raises the volume when the bass hits because it thinks its compensating for road noise.
PLEASE HELP!! I dont know what to tell the guy to do. Im thinking of just scrapping the whole thing if he cant make it work tomorrow. THANKS!!

Find the amp, turn the gain down on it. My guess is he has it tuned with the gain way up and now you can't control it at all with just the headunit, only the volume up and down. Start at a minimum on the gain on the amp, turn the volume up until it is as loud as you would want to listen to it and then slowly add gain until the bass matches up well.

Ill definitely try that. Also, Ive heard youre supposed to tap into a speaker for the sound. The guy said there was nothing coming from the subs when he did that and he had to tap into the bose amo itself. Does that make sense?

i wonder if the two speakers are out of phase. do the subs look like they are working hard but you dont really hear all that much? is so that could mean one is pushing while the other is pulling...instead of both pushing and pulling at the same time.
i'd have them install the bass adjustment **** anyways, it's a nice feature to have sometime. i'll be installing one on my car. You can buy ac ***** for the c6 that may fit on that potentiometer. if that does fit your style then have him mount it under the seat.
fej has a good point, worth a try. I'm not sure about the c6, but is he using a bose interface? You will need to play with the gain on that as well.
i guess maybe the first think you should do is find out exactly how he is interfacing the amps to the bose system and then maybe we can all figure something out. oh...and check the phase...i know from experience that this could make a huge difference.

did you read this:

check out the c6 sticky to school yourself a little so you can tell the installer what he's missing. he probably has never done a c6 install so he wont know the ins in outs of the bose system

Thanks for the help guys. Im gonna see what I can do with this new info. One question I still have though, is it possible to control the new amp and subwoofer with the bass controller in the stock headunit??

The bass level control on the stock h/u will control the bass output of the whole system, not just the sub. Personally I never recommend this route to control sub output, once the bass level is set it is a good idea to pretty much leave it alone to avoid damaging the OE speakers with too much bass. Most aftermarket h/u's will have a specific sub or non-fade output with a level controller, the factory unit is not equipped with this.

I had the same problem with the HU in my 02' trailblazer, the audio joint tapped into the rear speaker lines and ran the signal via line level converter to the subs.
Sounded like ***, and could never get the gain right, not too mention the aforementioned problem of not being able to control the volume of the subs via the stock HU. Pulled and it and never bothered again.
If you got one of those PAC adapters you'd be a ton better off, assuming your shop did the above. And from my exp. sounds like they did. PAC adapter would sync up the subs output with the BOSE HU, i believe.

I went to the guy armed with a ton of info. He tried to tell me this and that but gave up when he saw I knew what I was saying. Thank you all for all the great input. I think its gonna work out finally.

I find the head unit incapable of providing the range of bass control I need. With the stock system it's fine. However, with some real power and good amps, it doesn't cut it. Different music and different sources have different requirements for bass, and the HU can't guess that.
Currently, I'm using the fadar, b/c I have eliminated the rear channel and have the subs hooked up to the rear RCA's. This works fine, but it's a little inconvenient. For this reason, I'm thinking of adding a bass control **** to my system.
ScottFX - what's a potentiometer???
