I just baught a American bass Amp, its an older model ( like an 02) i think its about a 600wt, im not sure..it dont say on it.. it carrys a 40amp fuse, i got it connected to a sony xplod 12'' 900wt...(the older ugly type) My problem is every time i switch a track or station the amp goes on to protection , i checked all the wireing..its next to perfect.. i got a 60amp fuse coming off the battery to the amp, i used 4gauge wire, for the ground and power, i checked the power level coming from the remote wire and the power wire...there both 12vts.. The the entire system sounds great except the turning off part... the only way to get it back on is restart my car or disconnect and reconnect the signal wire. The signal wire is coming from the deck..and the deck is a older panasonic....

anywase..id appreciate it for some advice.

Switch RCA's to another set from the deck (if it has more than one), see if that helps.

If not, check your remote wire for voltage while someone changes the track, see if it stays constant.

We'll take it from there....

also turn down your gain on the amplifier ... on some decks the RCA's will induce a clipping noise when changing tracks and what not (especially if the deck isnt grounded properly, this will cause the radio to look for ground through the RCA's) anyway the gain being to high, can cause the amplifier to clip, and maybe protect.

What ohm rating is the 12" ? How do you have it hooked up to the amp? Bridged or not? If the sub has too low impedance and your amp is not rated to provide power to a low load, the amp could go into short-circuit/excessive-output-current protection mode.

Also, as the other guys said, I could see how a poorly grounded headunit might try to channel ground current through the RCAs, which would be bad and might cause excessive input current through the preamp circuit and the protection circuit to kick in.
