Question about Jl Audio 300/4 Car Audio Amplifier
I recently acuired this amp from a friend because it was broken and he did not want it. it had already been opened up and i could see 5 resistors were very well darkened and 2 ceramic disk capacitors were burnt as well. the 5 capacitors seemed to be from the left or the right channel. well i replaced all the resistors and ceramic disk capacitors. and put the board back in its case. when i try to connect the Positive wire, Then the Negative, The negative wire will spark as soon as it touch the screw. ( and this is without the remote wire or anything else hooked up) or if i coonect the negative wire to the amp, then the + 2nd i also get sparke and it seems like the negative i hooked up came close to welding itself to the connection. Help?
The power transistors are shorted out and must be replaced. If you contact JL they will fix it for a flat rate. That amp is well worth it.
