I have installed my gm3400t amp but it will not turn on. Have verified power and ground. Light will not come on. Can you help?

Did you check the remote wire? Make sure it is hooked to the radio is wired directly to the amp. You need to verify that there is 0.5 amps coming through the remote wire. If this is ok, then there is a problem with your amps power supply. (that is if you did verify by multimeter that your power and ground are good). Hope this helps.

No, make sure the vehicle key is in the aux or on position. If this still doesn't work, recheck the wiring. Also, make sure you have a good ground.

How to connect an boss amplifier

Assuming you have an aftermarket radio. You must remove the radio so you can attache your RCA cables and the remote turn on. Run these down one side of the vehicle back to the amplifier. Run the power wire from the battery back down the other side of the vehicle to the amplifer (remember to place your fuse within 12 inches from the battery connection. You will need to find a grounding point. I recommend removing one of the side carpeted panels to do this. You will be able to find the frame. Make sure to sand around where you will be connecting the ground. Hook wires to the amp (RCA to correct color RCA wire inputs, Ground wire to (-), power wire to (+), and remote wire to it's screw terminal. The other end of the amplifier should have the speaker outputs for your subwoofer(s). Hope this helps. If you need more information visit

The radio will no turn on. we have all the wires connected the power cord is plugged in but when we press and or hold the mode button nothing happens. its a new radio that we are installing that was bought...

If it is a new radio first make sure your power wire is actually hot. Use a multi meter. Also you may have a blown fuse in the fuse panel. Check that. Make sure it is grounded as well. Improper ground will make it not power on as well. For this radio Blue = Remote that you run to your amp or power antenna. Insulate it if you are not using either. Black is Ground. Red = Your accessory wire and should only get 12 volts when the key is turned on (switched 12 volt source.) Yellow is your continuous power source. Hook this to your battery or other suitable continuous 12 volt power source. It also has a 5 amp fuse inline. Make sure it did not blow. Replace it to be absolutely sure. Use another 5 amp fuse. Never go higher. The other wires are for speaker hook up. If you do all this and still no power. You may have a faulty radio. Good luck.

I have a 2001 oldsmobile aurora and hooking up a pioneer 3200 model doubledin, I got a plug and connected all my wires mute, reverse gear signal, blue white, and green I can't even get the unit to turn on

You can test the unit by connecting the POWER cable from the radio to the positive terminal of battery and the ground cable of the radio to chassis, to test the pioneer.

If it works then the problem is on your cable settings.

Make sure to find the power cable from the car with a DC tester. Turn the keys off and test all the cables.

Then turn the key to accessories and test for acc cable, usually red cable.

God Bless You!

I have a deh1350 and when connected to a 94 corolla it simply won't turn on. I took it back and got a replacement one but the same thing is happening. Is there something wrong with the cd player or is it...

I know it sounds dumb, but make sure the key is forward. Ive dorked out and did this a few times. Some decks have a red AND yellow wire coming out deck wire harness. Sometimes you have to hook just the red for power, sometimes just yellow, sometimes both, maybe check that out. And it cant be the ground, cuz if you missed the wire, it would ground when you hooked up the antenna. Oh ya, sometimes when playing around with wires, you mess up and pop the radio fuse. Check that. Cold be blown

I have a 700 watt 2 channel amp (pioneer) that stops the whole sterio when the right and left sides are bolth hooked up at the same time. what is wrong? i thought the hookup was pretty much idiot proof. is...

One possible scenerio is one of your RCA's is pinched real bad. I mean you drilled a screw thru the RCA and its grounding out and shorting out.

2nd possible Scenerio is you connected on the back of the radio the rca to the input instead of the output. You have to hook up OUTPUT OF THE RADIO TO THE INPUT OF THE AMP. Any other way its wrong.

I just bought a factory radio to put in my Eclipse. After hooking up all the plugs, radio comes on but no sound comes out of the speakers.

Are you sure that there are speakers currently installed in the vehicle? There may not be, I have seen vehicles that didn't come with factory radios not come with speakers either. If you do have speakers you may want to take the deck back to where you purchased it and show them the problem. If you purchased it online, then you may be stuck with what might actually be a dead unit.
