[QUOTE="maddog1927, post: 6657587, member: 618293"] I changed out the factory head unit to one that has pre amp outs ( I was going to anyway) but the problem persisted. I got a DMM, no drop on either the main power or the amp remote. I also connected a jumper cable to the negative directly to the battery. I have isolated the problem to the 2 front speakers by doing the following tests: Disconnected the front channel RCA’s at the amp: Result: Good Reconnected left and right (individually) front channel RCA to the Amp: Result: Cut out Front and back channel RCA’s backwards (front to back, back to front): Result: Cut out Front RCA’s to back channel, back RCA’s / front channels disconnected: Result Good Disconnect front channel speaker wires from the amp (RCA’s connected): Result: Good Connected rear channel speaker wires to front channels: Result: Good Connected front channel speaker wires to back channels: Result: Cut out The common denominator here is that when ever the front speaker wires are connected anywhere, the amp cuts out. (Unless the corresponding RCA is not connected) So I think it is safe to say that the problem is with the front speakers or wiring to them. I do not suspect the wiring. I rewired and had the same results (originally fed via OEM wiring, now feed directly with new wires) How do I test the speakers? I did an Ohm test (speaker wires connected to the amp, system shut down) Results LF 3 RF 3 LR 3 RR 3 Sub 4 Any thoughts, ideas? [/QUOTE]
