you can do what ever you like, we are here to help, you don't have to listen to us.
Its okay, you havent bursted anyones bubble yet. Ive already did research on the equipment that im going to buy, and your figures are WAY off.
wiring for the radio is about 60 bux and i can have my radio work with my cpc ( http://www.installer.com/acc/honaux.html )
ive found 2 12" speakers for about 80 bux, and they sound great. Plus i already have polkaudio 6'9's in my car so i wont need speakers ( http://cgi.ebay.com/ws/eBayISAPI.dl...item=3059315658 ) Im still going to need a box for the speakers tho....maybe ill have get a custom one made, or just throw in some 2 speakers enclosure.
Found a 1300 watt amp for about 100 bux ( http://cgi.ebay.com/ws/eBayISAPI.dl...item=5700206135 )
So yeah, im not sure what store you worked at, but you were either REALLY OVER CHARGING, or you used prosumer equipment. Either way, i know what im getting, and its not going to be anywhere close to costing as much as you think.
Edit: So that would be about... $300 w/ shipping
but, audiobahn, is only for spl, they are **** when it comes to sq, also you need alot of power to push them.
also, if you can make that amp push 1300 watt, well, go for it, but that amp is a piece of ****, i will push maybe 300-400 watts rms, but that depends on efficency, and also how you wire it up
if you are going to do it right, then save you money, get on the internet and read, learn about car audio, and do it right the first time.
