You hooked the amp remote turn-on to the wrong wire on the back of the head unit. Disconnect it from the blue wire, connect it to the blue/white instead.
but it worked b4 untill i unpluged it 2day and grounded the parking break the same thing happend when i first installed it, it only sparks up the amp on tuner mode
That is because it is hooked to the wrong wire as stated above. You hooked it to the power antenna wire (IIRC). It works in tuner mode because it receives a signal from the power antenna. For the other modes, the antenna wire is note engaged so no signal. Connect it to the blue/white wire and you will be good to go.
o.k blue/white wire to amp remote.....k thanks guys i'll tell you tomorrow see if it plays fine...another lil ? can i buy a remote for this because i bought it used and it didnt include it?
