LT EXT w/ Bose - Adding Kicker - Please Help

Hi everyone, I just joined today. It seems like a really helpful environment here. I'll be glad to get to know you guys/gals.
I just purchased a '05 Trailblazer LT EXT 4wd w/ Bose premium sound last week. The Bose sounds great, but there are only 6 speakers - 2 in-dash and one in each door - so if i am tailgaiting all the sound is up front and there is like zero bass in the rear door speakers...the ones in the front have nice kick though.
Anyway, I did some research and bought 2 sets of Kicker KS60 (6.5") and a Kicker 350.4 amp from crutchfield.

I thought about a sub, but it would just take up too much space in the trunk area...and i don't need all that bass. Anyway, I would like to put 2 of the Kickers in the trunk hatch and 2 somewhere around the 3rd row seat, which would mean cutting up my brand new ride, but I think it needs to be done. Any suggestions on how to go about this? I have a 4 gauge monster wiring kit from a previous circuit city installation which I am pretty sure I can reuse, but I would also need to know which other wiring and tools to get...and how to run the wires throughout the TB...especially into the trunk hatch.

Any help would be appreciated.
Thanks.

David.

ok to simplify things... My 1st question is, does the Bose Head Unit have RCA jacks so I can run a 4 channel RCA cable to the amp or should I tap into the speaker wire and use the high level inputs on the Kicker amp? If this needs to be done, how do I go about it and how will it sound?
Or do I need something else all-together to get the job done.
Thanks,
David

I dont know about this headunit your talking about, but the only way to find out is to take it out and look. I would almost think you have a factory amp if its a premium sound setup, and in that case, I have no idea. A sub would sound really nice in that SUV though...any 12" around 200-300 rms would probably make a big difference for your soundstage, since you said that it hits pretty good up front. Having less sound in your back doors is probably good, but not for passengers. You should have bought a component system to hook up in the back, and placed the tweeters in a high position so the sound would still be clear and nice for everyone without too much dominance. New vehicles might be hard to find spots to put speakers, especially doing it yourself. Look around though, there might be lots of opportunities.

I bought a PAC AOEM-GM24 (Add an Aftermarket Amplifier to Factory Sound System) for $31.99 from buy.com.
I contacted PAC and the guy said this is what i would need, so i got it and a set of monster RCA jacks (i already had one set from a previous installation).
I am sure the kickers arent the best thing to add to the bose system, but i'm sure they'll be fine. I did think of a sub, but there really isnt a while lot of trunk space behind the 3rd row seat of the trailblazer...and i have one of those rubber protector mats back there, so it just wouldn't look right.
anyway i am going to put my amp in the storage space in the trunk (with the lid off of course for air flow) and run the wires under the carpet.
This will keep it out of the way when i am packing it up with like camping stuff or tailgaiting stuff.
It's just not funtional for me anymore to have a huge box taking up all my trunk space. haha.

do you have to have the 3rd row seat? do you normally have that many people? cuz that would give you mad room. its your ride but a sub would sound real good.

yeah i have the 3rd row seat...and no i do not normally have that many people in my car, but if i ever do have that many people, i would like to be able to fit everyone without having to move a sub/amp around. we'll see what happens, but for now i will be putting in the 4 kickers. the only problem is cutting up my brand new molding....ahhh!!!

I installed the products from my order in the Trailblazer yesterday...kicker amp in the little storage area...2 speakers in the hatch...and 2 speakers by the 3rd row seat.
I used the PAC to run the RCA jacks and some of the speaker wire for the hatch speakers because the wires that came with the speakers weren't long enough. The 3rd row seat speaker wire was long enough to run to the amp.
Now, the ones in the hatch work perfectly, but the ones by the 3rd row seat have this click/rattle thing going on. It's not the speakers because I switched one from the hatch to the 3rd row and it still has the click/rattle. It's not the RCA jacks either because I switched the the front and rear channels and the click/rattle is still in the 3rd row.
Do you have any idea what this could be?
Could it be that I only used some of the speaker wire for the hatch and not the 3rd row? I don't see why this would cause a problem, but I am definitely no expert.
Thanks

sending the amp back to crutchfield...99% sure its the 2 speaker outputs on the amp for the rear channel

everything is working fine now if anyone cares...i cant even turn up the volume most of the way like i did when i just had the bose in there...if i would it would kill my ears its so loud. and it has enough bass for me.

did you put subs in too ?

no subs

I was just gonna say that I put my subs in the door panels ...... an 8" sub in each door. You don't give up any space that way
