I have the JL XD600/6 powering my c2-650 and my JL650 coaxial rear and plugged 2 10 inch JL w1v2's. The whole system sounds great, clean sound with nice bass to add to quality. Such a great amp I am sure you wont have any issues powering your system.funny enuf, was chekin out the jl XD600/6 amp to run all the speakers. plus i already got a powered 8'' bazooka as sub. wot do u think?
I personally would go with a double din, you want the screen size and with a single din you have to worry about the motor going bad or jamming issues. More moving parts and when it comes to the headunit less that moves the better.
connector C use pin 1-6. it is IGN power controlled by ignition. use a relay though. I mounted mine in the trunk and grabbed 12V from my distribution block.
I don't understand what you mean by connector C use pin 1-6. Do you have to open the dash to get at the remote wire connection?
