JL Audio is the best there is!!!!.... just to start lol. I have a high output 12w6v3 with a slash 600/1v3 and all I can say is WOW!! The bass is crisp & clean. The lows are insane!!!! It hits every note no matter how fast it is(HEAVY METAL)!! Now I've listened to a lot of audio system in my day and JL Audio is the best quality out of all the other brands #1. But if u don't want to spend the BIG money on JL then get some kickers but EVERYTHING ELSE IS JUNK!!!!!!
