Amp works but no sound from sub

Ive checked and double checked all my connections between the deck amp battery and sub. no wires are exposed. recently a speaker was shorting out on my chassis because the magnet in the speaker attached itself to the chassis so all speakers didnt work. i readjusted the speaker and secured it the 4 speakers worked fine but my sub didnt work, i tried using another sub but still didnt work, i also tried another headunit and still nothing. my amp is only about 7 months old and i'd had 2 have to purchase a new one if mine can be repaired. its a sub is a 1200 sony xlpod headunit and speakers are pioneer

    I have the same amp and I have two JVC subs I am trying to get working...No sound is coming from the subs and they are new out of the box. I got rid of my last subs because I thought they didnt work. The light is on inside the amp but no sound is coming from the subs.

Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

My speakers do not work but my subs do.


Good day sir, hi, there reason why speakers don't work could either be the folowing:
  1. you speaker voice coil is burnt, to test, you need to get the door speakers out and locate the terminals, prepare a 1.5 double AA battery, use this to test you speaker. connect a wire from the negative of the battery to the negative of the speaker, and the positive battery to the positive terminal of the speaker with a series of gentle taps, you should hear clicking sound. if not replace the speaker.
a9b085b.gif Do it on the other door speaker.

2. check your speaker line from the amplifier to the door speaker.
3. check your power amplifier for loose and improper connection.
4. check your power amplifier itself. Thats it.

Its a little work, visit your local electronic repair shop if your speaker still won't work.

I have an Alpine MRD-M605 amp that recently has started having issues. My subs only produce sound when my deck is turned up full blast. The setup had been working for over a year with no problems. The subs...


If your deck is aftermarket; Does it have a dedicated Subwoofer output? if so, check the control in the deck (sub gain). If you are using a factory radio, and a high to low level adapter (speaker wires to RCA), it may be bad (not too uncommon) or check your fader front/rear any difference? Otherwise, you have one of two problems. A bad preamp in the deck or a bad pre amp in the amp. Both are fairly uncommon. More than likely it's a setting. Hope this helps

Whining sound in speakers that changes with RPM.


Check ALL the ground wires. Did you use a fuse block power source for the subs?

Constant Power wire draining battery HELP!


Okay, I think I have it. The red and yellow wire into the deck need to be connected to two different power sources.

The red wire should only be hot when the accessory switch is on. The yellow wire is for constant power to maintain memory in the deck.

Connect the red wire to a source which is only hot when the ignition switch is in accessory position -- that should solve the problem.

Make Sure the remote wire is connected from the radio to the amp, its normally a blue wire. Here is a picture of what the setup should look like.
