I am trading in my C6 today on a C7 and I pulled out my amp and subs. I was wondering if I will be able to use them in the C7. Double D hooked me up with the Pioneer and install kit I had in my C6, but the C7 comes with nav. is there a amp kit to hook up the amp to the factory nav on the C7? Has anyone done this yet?

We have been using the Audio Control LC6I as a recommendation to add a amp to the stock C7 radio.

135.00 for this unit.

I am just starting my research on upgrading the stock C7 Bose system, and like the OP I would like to keep the Bose HU. I have a few questions:

1) Does the Audio Control LC6I take the place of an amp, or does it get hooked up prior to an aftermarket amp?

2) Is it mandatory to use something like the LC6i if you are going with the Bose HU?

3) Will the LC6i retain all of the Bose HU functions (EQ, Centerpoint, AudioPilot, fade, etc)?

4) Can the PAC ADD-GM24 still be used on the C7 Bose system (I'm assuming this plugs into the connector that would normally plug into the Bose amp, and then into either the Audio Control LC6i or an aftermarket amp)?

A LC6I is a fancy line level convertor.
If you are just doing a sub and keeping everything else
stock, the LC6I is overkill.

You could use a SNI35 or a LC2i or just grab the signal
at one of the speakers(full range).

I would also recommend using a LC-1(volume ****)
so you can adjust the bass.

If you plan on amplifying the door speakers you can use a LC6I.

In my opinion a better choice to work with a factory radio and
using aftermarket amps(if you ditch the Bose)would be a

1)Audison Bitone
2)CleanSweep
3)LC7i or LC8I

Also with the 3 choices above the best bet would be to
change out the door speakers too.


Hope this helps.

1 - it provides a line level RCA signal to be used as an input to an amp

2 - see post above

3 - yep

4 - Dennis will have to answer this one, but my guess is no or he would have recommended it. If someone can send me the audio section of the C7 service manual I can figure it out for you.

Thanks for the reply's

I've just ordered the extreme insulation kit from crazy cowboy to help with cabin noise.

As for the audio part, I'm thinking about doing the following:
-get rid of the 3 speakers in the dash as well as the rear speakers
-keep the bose HU
-Maybe use the Audio Control LC6I to improve the bose HU performance, eliminate any electrical noise, have the system turn on and off at the proper time, etc.
-replace the door speakers with a good set of 6.5" midrange speakers, 1" tweeters and a crossover.
-replace the 8" sub in the rear, possibly keeping the bose enclosure.
-Add a 5 channel amp.
-Maybe add a processor/eq?

Does this sound like a reasonable plan?

My goal is not to have the worlds best, or loudest sound system, but to simply improve the sound quality.

Thanks

-replace the 8" sub in the rear, possibly keeping the bose enclosure.
-Add a 5 channel amp. Bad idea, the Bose factory sub is made for that enclosure. 9 times out of 10 a aftermarket sub will sound bad in that enclosure.

I assume you were just responding to putting a new sub into the stock Bose box and not to using a 5 channel amp?

Speaking of the amp; If I'm running a mid range speaker and tweeter in each door plus a sub, do I need a 5 channel or a 3 channel?

-Maybe add a processor/eq? If you do a processor you won't need a LC6/7/8I

Which one would you recommend (processor/eq or lc6/7/8i) and why?

Thanks

No I would not even put a aftermarket sub in a factory enclosure amplified. That Bose sub is specifically made for that enclosure. Most Bose sub woofer enclosures are designed to the the most out of a $10 paper woofer. Once you put a aftermarket sub in it, it doesn't respond well.

I would go with a 5 channel digital amp.

If you want the best sound quality reproduction available go with a processor. You can fine tune the system more with a processor.

If you want something more simple,budget friendly and want good sound thats louder (still a improvement over stock) go with a LC6/7/8

If the Bose sub enclosure is sealed it's hard to mess it up by changing the woofer. I would just check if its' ported, if not, most aftermarket woofers will do fine.

bb996+r1

Its the opposite. Its very easy to mess up the sound by just replacing the woofer.

A) That enclosure was made specifically for that woofer.

B) The material of that enclosure is around 1/4'' plastic.
That is not conducive to providing enough structural integrity for
a higher output aftermarket subwoofer.
C) The location of the enclosure in the C7 is not made for maximum output. Its made #1 to be out of the way, #2 to add to the low end sound of the smaller speakers. Not maximum output.


JL Audio has been doing stealth boxes for over 25 years. Its a little more science involved that just swapping a woofer.

Just so we are on the same page. Are you telling us that the OP can remove his factory sub(8'') replace it with an aftermarket 8'' and achieve good bass?

Also looking forward to seeing your build and how you tackle the system.

Can't wait to see what the sub enclosure looks like too. My research shows that the 8'' sub that's in the C7's
is a specific Bose one. I don't think the holes with match and also an aftermarket 8'' subs mounting ring
looks like it won't fit.

That being said you have a C7 and you could post photos of the factory box once its removed.

SBC_and_a_stick

Yes. There is a sea of options in the aftermarket. You can get more output, lower harmonic distortion, better low end extension. An MDF spacer is usually all you need to make the speaker fit.

I won't be messing with the stock box, I don't even have one since I have the 9 speaker system. I'm building something from scratch.

Here is the factory box btw:

Anyone know what the replacement speaker sizes would be. I have several speakers left over from my c5 and c6 stereo replacement projects. Looking to find out what I have that will work and what will need to be purchased.

exact same as the C6...
3.5 and 10" in doors
5.25" in rear.
I ahve adapter plates for the doors as well
