Amp Problems...need Help

[redbaron80]

James had his amp shut off last night, and it has not turned back on yet. I'm gonna trouble shoot it tomorrow with him. Is there any way his amp could BLOW, it is fused at every spot, up front, before the positive hits the amp and before they hit the battery in the rear?

yea there is, there is always a chance, i have a 300 amp fuse on my 2000 watt amp (off brand) fired it up for the first time, cranked it, heard it pop then shut off, checked fuses they were great, amp now is always in protect (have a really heavy paper weight now) hope you can find out whats wrong with it, maybe its just a easy fix

300 amp fuse is to big for a 2000 watt amp esp if it is a off brand as you say because it probolly does not make rated power rms power let alone 2000 watts. You should of been using a 200 amp fuse, if not a 150 amp.

fuses sizes should be around the amperage draw of your amp. this way the fuse blows before the amp blows.

the amp put out 1500w rms at 1 ohm, i had it on a 150 amp fuse before and it kept blowing it over and over, so i upgraded and it stopped working

150amp fuse should almost be fine for a 1500wrms if it blows, try a 200amp, dont jump double the fuse size right off the batt!

If the fuse kept blowing the amp was being pushed to hard, clipping, and was getting warm. Fuses dont just pop for no reason.

I learned that trying to see how much power I could get out of a amp that was found at the junkyard my friends work at.

This is the amp.

It is only 4 ohm stable mono. LoL I was running it at 1 ohm mono.

Its fuse rating is 60 amps (2 x 30). I fried them in a second.

I upgraded to 80 amps (2 x 40). They fried in about 5 or so minutes of bumping.

The green wire you see in the one pic is a 10 gauge 150 amp fusible link out of a dodge caravan at the junkyard I put it in with the 40 and eventually fried, amp kept playing for a good 20-25 minutes at a time for a few days then just stopped working. lol I took it apart and the solder melted off the board on the positive power connection.

I soldered it up, bypassed the fuses all together with some 8gauge, and beefed up some of the other solder connection. It played for about 15 minutes and fried rofl.. But it was a little champ.

A guy had 2 of them for sale on another forum for $150 each
