amplifier

[ldavies]

hi all
ive finally got my sub and amps all wired up and working but theres one problem i need help with.
ive got my 2 front speakers wired up to my jbl 600 amplifier and when the x over switch to off or either to hp when the stereo is turned down its making a loud funny noise but when i switch it to the lp setting it goes off but theres more sound coming out of my rear speaker than there is out of the 2 front connected to the amp. they seem to have more bassy sound that anything else.
can anyone help please.
hop this makes sence to you. cheers

forgot to mention when the car is running it gets even worse

is it the engine sound?? becuase thats what ive got at the moment either a dodgey earth or dodgey rca cables have a look at where you earthed it make sure you have sanded away all the paint if not you may need to replace the rca cables

the best way i could really describe the noise is like when youre searching for a radio station and you get like that really bad crackling sound.

As said mate, i would put my money on it being a bad earth.

However, normally you get a whiring noise through them, and sometime you get static, i.e. when your indicators flash, or when you put the lights on etc.

Get a good earth to it, then if it still doesnt work come back to us:)

well checked everything i can possibly think of and even bought a capacitor that connects to the altenator and still no joy.

power cap will not do it any good

you checked connections on the alternator???

also check the belt is ok and tight

but like everyone said its most likely a bad connection somewere

in these cases i usually rip it all out and start again
