Ill tell you this I got 2 l7's 2008 series pushing about 1500 rms and I mean true rms. I just got my system hooked back up after haveing it uninstalled for a while and I have not put my powercap back in. My lights look like they are strobes when my bass hits and it dont have to hit hard at all for em to dim like hell. Just wait and spend the money on 1/0 gauge wire and set it up right. If your not going to do it right dont do it at all it will just screw your car up. If u run that small wire it will burn the wire up 4awg is good but ur gunna loose a bit of power though it going to that amp. You can find good wire kits online suprisingly on ebay I got mine for 75 bucks thought it would be cheap wire thick insulation on it. Was I ever rong It only came with 17 foot not enuf for me to run to my cap and back to my amp so I got some more 1/0from my local shop. Its true 1/0 from jl audio and its the same as the sht I got on ebay
