I've decided for my four door tahoe z71 2004 on going with a Pioneer AVH 4400, Was going to do the app radio but it only has 2 preouts. Along with that i am going to be getting a crescendo 5800bc amp, a total of four FI Bl series Subs (either 12 or 15 inches) with the cooling option, not sure on 1ohm or two ohm impedance. Along with that i will be building my own ported box tuned to 35 or 30 hz. For the tweeters i am just going to be running two crescendo ft1 and four pwx 6.5. Haven't chosen the amp on those. I do know i will need to upgrade my electrical system on my car. I'm just posting this for some feed back on what i could enhance or if 15 inch subs would be better than the 12 inch subs. on that not i want musical not comp, im not going to be doing any burps or anything, and also i mostly listen to electronic music and rap, but still would like to jam some country from time to time.

There are a couple different ways you can go about this. You will need a Active capable head unit (I didnt look the specs on yours).

You will either need a small 2 channel amp for the tweeters 50w or 75w x 2 will be plenty. Then a 4 channel amp for the mids. 100w x 4 will be good on that one. Or you could run one bigger 4 channel and run the tweeters off 2 channels and the mids off the other like I am. I have a 150 x 4 and have the amp turned way down on my tweeters and then running mostly rms to my mids on the other 2 channels.

Obviously 4 15's is alot more cone area than 4 12's. It will also require much more space for the enclosure. Your choice. This is a very large setup you are attempting and will cost a lot of money to run properly.

My setup is somewhat similar and I have 4 XS D3400 batteries and also a 380amp alt and I could still use more battery.

I hope you have 5, 6 or 7k to spend and also do all the work yourself. lol
