If an amp gets wet you must dry it before turning it on if you didnt for whatever reason you may have shorted the lines and blew something. You will probably have to send out to get repaired

Probably because when you repair amp's sometimes they don't run 100% when repaired

I would go with a 40 or 60 amp fuse, this should be ok, you will hardly every run the amp to full capacity so its better to be safe than sorry.

Here is the closest manual i could find. Read through it and see if the specs are close to yours.

You will need "adobe reader" to open it. Adobe reader is free.

Hello luistecnico2,

Those cross-reference OK. Go to www.mouser.com and do a search on both numbers. You'll find that one of them was manufactured by STMicroelectronics and is currently obsolete. The other is manufactured by Fairchild Semiconductor and is available at a cheaper price than the original.

Hope this helps.

probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.

same thing happened to me a while back it is one of the reistors inside the amp, when you took the turn it anything bumped it or it fell it might have broken off, shake it and see if anything inside rattles, if so then you need to take it to a repair shop or some who can solder
