Re: Pioneer Car Stereo blows fuses
You have a short on the right side of the vehicle, you mention a fuse to the right channel speaker keeps blowing which tells me that either the speaker is blown or the wire running to it from the deck is touching metal somewhere. Check the wiring, or install a different speaker and see if it takes care of the problem. When you turn right the system goes off then back on tells me that there's a short. Check all of your stereo related wiring.
I also have this problem also so i took it apart with my dads mig welder and smeared peanut butter and bacon grease all over my mother board and it didnt work so scratch that idea then i connected my ground to my battery cable and that seemed to do the trick a couple days then it started again so i put a 0 gage wiring harness and it helped and my dad a reeetard and that he hates me .

a 'reset' of the entire stereo should be able to be accomplished by disconnecting the battery for several minutes: alternately if you remove the faceplate there should be a reset button you would need a pen to press, however you should be able to find the EQ levels and set the balance and fade I think it is so the rear produces sound, if that is not the case, I would check wiring to make sure nothing is loose. I suppose it could only be a software/firmware problem with the stereo itself however, if you have had this happen before and it was fixed without tinkering with the wiring.
First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)
Check for shorts to ground in the speaker wiring, the speakers themselves, total Impedance, especially woofers. Proper size power and ground wire and all connections. Use a Ohmmeter or find a friend with one that knows how to use it, If all else fails RMA . Good luck, sumthin
The amplifier probably has shorted output transistors.
Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
If your speakers are wired for an impedance below 4 ohms mono or 2 ohms stereo, that would make it shut off. If you have a speaker wire shorted to ground, it would also cause the amp to go into protection.
If the speakers are not the problem, it may be shutting down because the voltage at the amp is dropping too low.
