I want to buy 4 2008 15" Kicker L7 but i dont know if i should buy 2ohm or 4 ohm? I'm also buying 2 4400 4 channel amps. which kind of subs should i get? and what are the goods and the bads of 2ohm and 4 ohm?
the difference between 2 and 4 ohm voice coils are the different wiring possibilities... The amp you decide on will determine what v.c. configuration you will need for optimum performance.
If you are stuck on the L7's, just go w/ the DVC 4ohm version. That way you can get a pair of 2krms amps that are 1ohm stable and that will power the subs fine.
BUT before you buy, what vehicle do you have?
You are going to want a minimal of 16cuft for those 4-15's
oscar, im not downin you in any way but you dont seem to know too much about car audio.
im no subwoofer guru myself, ask anyone here.
but 4 15" L7s is an 8000 watt system. no car's stock electrical will hold up. and im assuming you havent put thought into having to do any more batteries, a High Output alternator, 0ga wiring, etc.
also, L7s are NOT the best subs. they do get loud, but not the best SQ. if you can get a nice box made JUST FOR THEM as well as one thats just for YOUR car, it would be a nice setup with just 2.
