Ok I had a system in my car untill i was robbed. Now i have to start from the ground up. This is what i have so far, Kennwood excelon KDC - X959 for a HU. Now i am looking at some rockfords for subs pref 12's i guess. Now for amps I want to run a 2 channel amp for my subs alone and a 4 channel amp for my speakers. I have been looking at Profile's series of amps can some of you guys give me some thoughts on how there amps are or what are some good amps that put or 150 to 200W x2 at 4ohms. Also what is are some good 4 channel amps that i can use to run my speakers too. The setup I had before was an older model of excelon series HU w/ kennwood Digital EQ, two sony amps one 4 channel and one 2 channel with a bandbass box with two rockford 10's. Thoughts and some opioins would be greatly appreciated thanks
