ok my plan for my car is...the first # is the # of total types of speaker not # of sets...

4 15" S15L7 kicker subs
4 7x10 I7103 3-way
2 ZR1000 amps

i dunno if im forgettin anything... does this sound like a good setup?

im takin out the back seats so i can put the subs there and the other speakers go on the door and window panels and if theres anything missin or left over ill put that beside that subs...

 

A couple ideas I'll throw out to ya.

The ZR1000's are about 1100-1200 watts each. If you do an L7, do that per woofer, not per pair. The L7's like larger vented enclosures. They will gain between 3.0 and 5.9db in a vented enclosure.
I personally would do either two L7 15's in a vented box, like 6.0 cu.ft each, or two twelves. The twelved would work awesome in a 3.25 cu.ft enclosure tuned at 37hz. Be sure to add a sub-sonic filter.
Thetwelves are recommended to handle 750 watts, but they will handle a ZR1000 on each easily. People do it everyday and are getting really good numbers.
So check out our website ( www.kicker.com )for box recommendations, as it will help give yo dimentions and ideas on your enclosures.
But a good match would be two 12's and a ZR1000 on each.

Later.
