Check to see who the manufacturer is. The Acoustic Research name was sold a couple of times. I think yours may be Recoton. If so, you may be able to get some help from them.
The transistors at the output stage of the sub amplifier circuit might be shorted so each time you power on, the circuit draws a very high amount of current which causes the fuse to blow. It's definitely a problem with the circuit so using a higher current rated fuse would probably just result in damaging the amp even more. You should ask a qualified electronics technician to take a look at it. I hope you can fix it.
Greg, If the fuse keeps on blowing there is a problem with the internal amp. It was probaly caused buy a electrical power surge, Or a (********) up Sub patch cord,
The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.
you must check your cables first and try witth anoher cables if the problem remained you will have internal problem inside and needs to fix in service center
It would be very dangerous to bypass a fuse. If it keeps blowing, bypassing the fuse will only create lots of internal damage and maybe a fire as well. The fuse is blowing for a reason, the amplifier is not going to somehow start working because you bypassed the fuse. You also need to stop trying to turn it on, every time it blows the fuse, it keeps stressing the components inside. You have a shorted power supply, probably water damage as well since the power wire got wet.
I repair car amplifiers for a living, and can tell you with all honesty that bypassing the fuse would be a terrible mistake to make, the amplifier would end up being un-fixable with holes burned right into the board.
Please, just take it in for service or get a new amplifier. That is the only sensible thing to do. The amp will not start working bypassing the fuse, it will only start smoking.
