BIC PL-200 blowing fuses

[Rob_63]

Anyone have any experience with the BIC PL 200 blowing fuses? I have had this sub since shortly after they came available so I am sure it is out of warranty.

I took the fuse down to my local electronics supply shop and they sold me a pack of replacement "slow burn" fuses, replaced it with one of the new ones and as soon as it went to power up the fuse popped.

The sub hasn't been used hard, the system that it is on sometimes would go for weeks without any usage.

Is there anything inside on the amp that is known to go bad that I could replace or will I end up replacing the amp?

thanks

I sent an e mail to BIC, maybe with any luck they will do a goodwill fix since I am not even sure when and where I purchased it nor do I have the box around any more.

Pull the amp and see if there are any touching wires. In my experience with sub amps, the internal fuses blow when they are indeed damaged, the external fuse blows when there is a short somewhere... Try a different power cable... I had a sub that called for a 4 amp fuse but if you really pushed it it would blow, so I put an 8 and it worked until I sold it years later... But your problem sounds different since it is popping them as soon as you put them in...
pull the amp, trace where the power goes after the cable/fuse/switch- it may be as simple as putting some shrink wrap over a wire that melted against something hot or vibration rubbed a bare spot in... if you dont see anything, try putting a good fuse in while the amp is out, turn the lights off {when you are clear from the amp} and then plug the unit in, see where it is flashing behind the amp..
