Amp wont power on

It's not the amp that is the problem, since i swapped it into my old car, and it powered my subs fine. but i cant seem to find the problem. All the wires have been hooked up right, the ground is attached to bare metal on the chasis, and the power to the battery and inline fuse is hooked up, and the remote is run to the blue/right wire on my head unit. I thought the problem was the ground leading to paint behing the mounted bolt i chose, but i sanded down the paint and it is on bare metal. Then i thought that the amp was not getting enough power since i shared it with my sattilite radio power wire too, but i disconnected it and it still doesnt power the amp. There is an alarm system that came with the car when i bought it that also shares the battery positive, but i know nothing about the system, and im sure that it doesnt require any power except when i turn it on/off. The amp is running two 10" alpine type s subs, and like i mentioned before, it workes fine with tthe wire setup in my old car. The car is a 1999 toyota solara, and if anyone knows anything, please HELP!! Im out of solutions!!!

Well if the remote is connected to the radio then i think u shouldnt dissconnect the radio. try some other ground. sometimes not all bolts and nuts are good gounding. try the truck latch or something.

Re: Amp wont power on

The only effective way to troubleshoot this is with a digital multimeter. Test for voltage on the power terminal and the remote terminal (using the ground terminal for your black probe). If you have voltage on both terminals, check the amp's built-in fuses; if they're good, then you must have a defective amp. If you have voltage on the remote terminal, but none on the power terminal, check your fuse and fuse holder at the front. It's not unusual to have a blown or defective fuse that looks okay.

Amps turn off and cut out

You just gotta get your gains set up right. Look Up "How To Set your Gains with a Multimeter" your over powering your subs or speakers and your amplifiers cant keep up. you also have to make sure your speakers are wired to the right ohms. your amp cant handle. if your amp cant handle, for Example:1 Ohms your gonna blow your amps. ......Speakers and subs are a science too.

Pyle PLA885 amplifier blows 25amp fuse. Ideas?

signs of a short, did any wires touch while you where hooking or un hooking the amp? if not then the internal power supply probably has a short in it and needs to be repaired. you can swap the fuse for a good one and hook it back up and make sure you don't touch any wires and if it blows it again then your issues is internal and will need repair if it doesn't and everything seems fine then wires could have touched or the amp was ran past it's limit and blew the fuse to protect it self. good luck and ask any more question you have

I have a rockford fosgate punch 150 and it will power a small 5 1/4" speaker, but doesn't seem to push my 15" subwoofer. I am reading 4ohms across the sub so I'm assuming that it is fine and that there is...

amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

Will not power

are u sure you didn't blow a fuse? check the fuses to make sure you did not blow one because the amp will not work in that case. make sure you are not over working your amp as well because it seems like that amp is not big enough to power all four of those subs. usually 4 channel amps are used to power speakers not subs. what is the rms on your subs and amp? i could better tell whether your amp is big enough. thanks hoped this helped

Kicker 750.1 Amp wont play music

it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs
