yeah they should be long enough, they are a good like 5-7 feet maybe? maybe longer? the RCA's were just tied up in a bundle when they were back there connected to the line outDid they charge you extra? Are your existing rcas long enough?
Switched 12v.
WTF???bull shit. the TURN ON is for the POWER wire. the GND is for the GROUND wire and the 12 volt is for the REMOTE wire.
if you wired the remote to the 12v constant.. amp would always be on. Wire to the remote wire. If there is not one available, to the power antenna, if no power antenna, to the 12v switched.
