Phoenix Gold Phorum

I have a PG 15.0:1 when I power it up it just blows the fuses. I'm using 40amp fuses and I'v checked all the wiring in the car so I think it is a problem on the board in the case. Has anyone had this problem or have suggestions on what i should look for.

disconnect the speakers and try again. If it stil blows your amp is probably bad, if it doesn't then check the impedence of the speakers as one is probably shorted.

My speakers are good I have them hooked up to a amp right now

what he is saying when a speaker start to go it will cuase a amp to think its lower imp. so your speaker can be there installed but when they get old or worn out it can cause this problem

are you using a 40 amp fuse inline with the power wire? if so you need a 80 amp as per pg
40 will just keep blowing when the current is increased

I think if he's blowing a 40 amp fuse upon power up (assuming no music playing) there is another issue. I've been running an X200.4 on a 60 amp fuse for about two years now without blowing.

if your speakers are shorted, the amp can pop a fuse. They could be shorted anyplace along the wire or even internally in the speaker itself. By just disconnecting them and then powering it up we can quickly tell if its the speakers, or the amp. We need to isolate the problem to find it and this is one of the ways.

Could be stray wires at the speaker terminals too (possibly inside the amp, as wire fragments can and do find their way in there).

After that the most likely cause is probably a shorted transistor.
