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.

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.

MAKE SURE YOUR GROUND WIRE IS GROUNDED GOOD,,AND IT IS IMPORTENT TO HAVE YOUR REMOTE WIRE HOOKED UP. IT WILL BE A BLUE WIRE,,FIND THE HOT WIRE FOR YOUR TAIL LIGHTS AND HOOK IT THERE THEN WHEN YOU TURN YOUR CAR ON THE AMP WILL ALSO COME ON.THAT SHOULD STOP ALL THE NOISE AND POWER YOU UP.

I just installed a kenwood dnx7140. Everything is


Have you checked to see if the sub amp is turning on. Check to make sure you have at least 12 volts on your power as well as your remote turn on (Blue/White on radio harness).
If everything is hooked up correctly, it is possible that the preout is turned off. Some headunits have selectable preouts. If so you should be able to turn the sub on and off in the menu.
Hope this helps

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.

My subwoofers ''fight'' each other


YOU ARE CONECTING ONE OF THE SUBS ON THE INCORRECT MODE SO DISCONNECT ONE OF THE SUBS AND SWAP THE WIRES AND TRY.

Another question for zzedly about the speakers cutting out


So, as I see it, your system is hooked up like so:
  • Ch1 = Left speakers, front and back
  • Ch2 = Right speakers, front and back
  • Ch3 = One sub
  • Ch4 = Other sub
One thing you can try is swapping channels. Swap Ch1 with Ch3 and Ch2 with Ch4. Then see if the issue still occurs on the door speakers or do the subs suddenly cut out at loud volume. If the subs start cutting out, that means the issue is with Ch1 and Ch2. If you haven't already, check the RCA connections to Ch1 and Ch2 as well as the gain for all channels. If the gain isn't already set to about 50%, put it there.
