Additional Amp Install W Bose

[Chad1903]

Hello, First I want to say thanks to all of you that read this and take the time to respond. I know there are some of you out there that are wizards when it comes to this stuff... So I have read through the forums and I realize there is a lot of talk about installation of aftermarket amps but most are very vague when it comes to the actual process or are not specific to the USA 2nd Generation Bose, thus this is why I'm putting up a new post in hopes that I can get educated and also help others that are wanting to do the same thing.

My Car is the 2009 Mazda 6 (USA Version) With the Bose option. I'm interested in adding some more bass to the system while for the time being retaining the Bose Head unit and other speakers.
My questions are:
1. Can I connect the stock bass speaker input wires to an additional amp then feed that to a new sub? Would this damage the Bose amp? I'm assuming so
2. If I splice into the input side of the amp (Bass Wires) Can someone tell me where this is located at and what wires they are? I've seen schematics posted in other places but they are for the older generation models. Basically I'm asking for a wiring schematic.
3. I'm almost ashamed to ask this but in regards to signal travel: I'm confused what else is in the system, head unit, amp, eq where is the eq located? is it before the amp or after or is it in the head unit? I ask because I'm trying to determine if I will need an audio processor too such as the 3sixty from Rockford Fosgate.

I realize that my questions appear well very "low end" but for a do-it-yourselfer I think there fairly important questions to have answered while in the planning stages.
Any advice, pictures, links or opinions are very much welcome.. All except for taking it to someone else to do the work for me.

Thanks

Wow - no one responded in 3 weeks

Skipping the "bose is the devil" sermon, I'm going to give you 2 suggestions:
1) use the high-level inputs that most amps/powered subs have and tap it right at the factory sub in the rear

Don't try to tap the bose line-level inputs; I think they're somewhat higher voltage than normal decks (when going from my deck's RCAs the deck needed to be boosted to get full volume).

That's the simple answer.

2) Factory stereos usually drop the bass . . .bose is tricky like that because the lower frequencies get folded up into higher frequencies to trick the ears. If you want to do it well, you'll need a factory signal restorer; I think cleansweep does that, but it gets expensive quick.

To answer your EQ question: yes. The deck does EQ as does the amp . . . it's irritating.

Ask any questions you may have about this system; I'll get email replies now and I've mostly torn this system out of my car. I swear, I'm getting 2mpg and at least 5hp more since removing the Bose amp
