Definitely a second battery, caps are almost useless 99.9% of the time. Second battery in back, big three, 1/0 wire, but on 1800w you should be good alt-wise.

2. When i run the new speakers and subs from the pre outs on the back of the headunit what do i do with the stock speaker wires and the stock wiring harness?

Tape them off. Just make sure they aren't contacting each other. Unless your h/u has an option to shut them off.

3. Where should i mount the crossover blocks for the components, im debating under the seats, cause i really dont want to put them in the doors

Under seats = more wire to run. If you're going to have your interior out to do the wire, or any sound deadening, then shouldn't be a problem. You should be able to hide them away in the door panels though.

4. Is there anything else i should know before i do this, bad wiring, rap, ground points, etc....

Don't touch the power wire with your tongue. Seriously. It hurts. Lol

In all seriousness, use the least amount of wire possible. Make sure power and signal/speaker wires are ran separately, to reduce interference. Make sure you sand the paint away in the point you're going to ground to for best connection.

Oh, and sell me your system. That always makes everything better. ^_^ Sike.

Thanks for any help you can give me, ive already got the speakers and im buying the rest in the next few months, so any help is appreciated

You are very welcome, even if I'm of no help at all.

giggity.

1.should i remove the old wireing?
im definetly gonna remove the stupid old bose amp since all it does is take up space, if i did remove the old wiring how would i go about doing it without destorying anything.
and im deffinetly gonna need more clearance for the sub box and the two amp racks
2.also do you think i could swap out the stock grand prix bose speaker grills in the doors to the new polk audio grills, i work at a best buy so im sure i could pick up a set of grills that somone doesnt want from the 5 inch coaxials and make some sort of mesh to go in the middle, i just dont know how well they will install. I havent done any speaker work on this car yet, just stereo, subs, bass knob, and amp. Currently all it has is an RE SRx10D4 the kenwood head unit and a BOSS Diablo 600.2 amp . So im not sure about swapping the grills,
3. and ide sell u my system but its already gonna cost me an absolute pile of cash (somwhere around 2 grand) and ive still gotta save up the other 23 grand for the engine build, suspension,brakes,body work, and enterior
4.by the way that amp is BS don't buy it for the love of god, its cheap for power but i know its maby pushing in the 300 watt rms area and thats with 1 channel per voice coil which supposedly makes 230 rms per channel. It is sorely overrated if i hadn't gotten it for a ridiculously low price i'd be pissed off, an audio shop in town described my current sub/amp combo as a Cadillac powered by a go kart engine. But somhow it still made enough power to crack my rear view mirror

That's your choice. I left my door wires for now until I can get a good run to them. Someone with a Bose stereo in their car may be able to enlighten you more.

All in your personal preference. If you think the new grilles look better, then go ahead. That's all your choice.

Haha, I'm good, mine will do me fine for now.

Which amp? If you're talking about the AP amplifier, then you're seriously wrong. Remember, this is the AP1500.1D, the class D monoblock. It does put out rated. Several people on a couple different forums have posted clamped ratings and they do, if not more, damn near rated at 1 ohm.
