View Full Version : too much power from battery? too big fuse? Lesesneje 10-07-2005, 07:18 AM i have a sony XM-D400P5 amplifier. every time i hook it up to the power wire and turn on the amp, the two 30 amp fuses on the amplifier blow right after it turns on. Could this be because my fuse near my battery is too big and the amp is getting too much power? or is it something wrong with the amp? if it is the amp, does anyone know what could be the problem? iamrazor 10-07-2005, 08:34 AM what size wiring are you using? have you double checked for shorts? made sure the power wire isn't grounding out? Mulder 10-07-2005, 08:39 AM Fuse size/rating has nothing to do with how much current a device will draw. It sounds like there is something wrong with the amp and it needs to be repaired. Lesesneje 10-07-2005, 09:20 AM using 4 gauge wire with a 50 amp glass fuse. It seems like the amp is trying to pull more than the fuses on the amp can handle. and it happens as soon as i turn it on so i have a bad feeling that it has something to do with the amp. blkwrx02 10-07-2005, 10:37 AM If the fuses on the amp are blowing there is something wrong with the amp. ein86 10-07-2005, 11:29 AM If the fuses on the amp are blowing there is something wrong with the amp. waht they said mcowger 10-07-2005, 04:38 PM Are you sure the power/ground wire connections on the amp aren't reversed. calib17a 10-08-2005, 12:09 AM What ever you do, don't replace the fuses with a higher rated fuse at the amp, you'll burn the amp that way. You definitely have a short, that could be internally in the amp or shorting somewhere at the speaker terminals. You could use an digital multimeter, click it to ohms ground the black side and start checking speaker outputs. audio1der 10-08-2005, 12:30 AM Fuse size/rating has nothing to do with how much current a device will draw.

I believe blowing fuses most likely means a short in the power supply of the amp. |
