That sounds great, i'm just torn between whether i should wait for the level 4 xl's to get in stock or just go ahead and get a level 5 15". I have a 1600x1 @1 ohm Hifonics Gen xx Zeus right now but i might trade+cash with my friend for a RF power bd2000.1. I'll be getting a 3.5k and alternator later.
if your sure youll be getting the 3.5k go for the lvl5.
