i am currently trying to run a sub with built in amp through the standard cdr 500 radio. i have got as far as:
power cable connected from batt to amp
rca leads and remote turn on wire run down to radio and connected to amp
earth connected to amp
the bit im not sure about is connecting remote lead to radio?
and also i am using a speaker line output converter which i have connected the two sets of speaker wires but dont know how to earth it?
it says i have to connect the left and right negative to the earth and connect all three to the chassis earth of radio or deck?
any help greatly appreciated
