Red goes to your battery, black gets grounded to the vehicle frame, and the blue wire is the remote turn on wire from the radio. There should be 3 power terminals together. The red wire goes to power or (+), the black wire goes to GRD or (-), and the blue wire goes to remote (usually between both the power and ground terminals). hope this helps

I have a rockford fosgate punch 800 car amp and the problem i seem to be having is everytime i connect my remote wire to my stereo deck and i turn my stereo on it burns the fuse its only when i connect my...

Check the wires at the amp. Make sure that the wires are neatly bundled and clean cut when connecting them, a stray wire may be going under one of the connections from the battery input to the ground input of the amp, there for causing a direct short and blowing the fuse. I am assuming you mean that the amp's fuse is blowing. Get yourself a test light and test the wires for power. battery power?(12V) is always on and remote power(12V) comes on only when the radio is on(it should be the blue wire in color). Then make sure you have a very good ground, I always use the seat belt bolt or car seat bolt(direct to chassis). If you checked all these steps with no luck then the culprit may be your amp.

I need a color wire diagram to connect a pioneer head unit to a 96 chrysler concorde

GM speaker wires are usually purple, green, grey, and white if I remember right. 12v should be red and ignition should be yellow you can verify with a multimeter and use a battery to test positive/negative on speakers by connecting the battery to the speaker terminals if the speaker pushes outward the positive is connected tothe positive terminal

The amp works subs turn off after they are turned up restart and they are back on. Is it a bad ground.

Can't say for sure it is a bad ground but does sound like you have a intermittant connection some where. So I would start by taking the fuse out at the battery terminal, then disconnect and reconnect your power cable to the amp, disconnect the ground wire to the amp then reattach, then do the same on the chasssis side. Do the same with the remote wire. Put the fuse back in and test .

My sub woofer wont turn back on

Hello austin_optiz,

If you have had 2 units with the same problem, I'd say that yes, there is a problem with the "sound sensing" function of the auto turn-on circuit. Either it's not getting the correct level or one side is being shorted or grounded. Some vehicle speakers may have one side at ground potential which could cause the auto turn-on to fail.

If the Basslink operates normally otherwise, I'd recommend that you just connect a 12V + fused and switched source to the remote terminal. Wire it through a conveniently mounted toggle switch and turn it on and off manually.

Hope this helps.

I have a fusion sub and amp and have no instructions on how to wire this can somone please help ive got green wires red wire and a small thin blue wire

Hello nicole_murra,

The green wires are for signal input to the included amp and should be connected to a pair of RCA preamp outputs on your head unit. The thin blue wire connects from "remote" on the amp to a switched 12V output on the head unit (usually blue or blue/white). The red wire is for power and goes through the fuse to positive battery. You also need to connect the amp terminal marked "ground" to the metallic chassis of your vehicle, within a distance of about 1/2 meter or less. There's usually a short piece of wire with black insulation included in most amp wiring kits. If your Fusion sub did not come with such a wire, you can use any wire that is the same gauge (or bigger) than the red power wire.

Hope this helps.

I cant sem to wire it to 4 ohms because the terminals are right next to each other and i have no clue which 1 is which voice coil?

test with a digital multimeter set to ohms. if you don't have one of those laying around grab a 9 volt battery and run wires from the 2 terminals on the battery to 2 of the terminals on the woofer. if the woofer pops out you are said to be "in phase" (even though it has more to do with polarity that phasing but regardless) which means the positive from the battery is on the positive of the woofer and the negative is to the negative. those 2 terminals on the woofer are a single coil and obviously the other 2 terminals are the 2nd coil. now depending on what impedance each coil is will determine how you have to wire it to be 4 ohms unless they are 4 ohm coils which means you just use one coil and it will be 4 ohms on that woofer.

I have got a kenwood cd player but can,t install it into my vauhall corsa because i need a seprate battery 15amp yellow cable to run from the battery supply to connect up to a cable attached to the radio...

You can test one of the wires from the harness connector for a contant +12v with a test light. They are sold at your local auto parts store for less than five dollars. The harness connector that i'm talking about is the harness connector that originally connected to the stock radio. All of the connections needed to install a cd player are all on that harness wire. The test light is simple to use, all that's needed is for the alligator clip to be hooked to ground. And from there, you can determine from tapping which wires are for the power supply. The power consists of three or four wires. They are ground, +12v ignition, +12v constant, and if installing w/ an amplifier, the remote. This is the usual place most people connect the wires for a new head unit.

I need to know how to hook up a head unit in a 98 chevy lumina i dont understand the wiring in the car

The colors are as follows. grey/tan+ LF, green/ RF, brown+/yellow LR, dk. blue+/blue RR. You can also verify the speakers by using a 9v battery. Hold one wire on one terminal of the 9v battery then just strike the other wire for only a second DO NOT HOLD the wires to the battery for more than an instant. You will hear a pop noise from the speaker.
Orange is memory, yellow 12v switched, black ground/earth.

***Warning!!!!!! There's 2 yellow and 2 grey wires (other grey is dimmer). If the original factory harness is still there and not cut up, all the speakers will be next to each other on the plug(s). If not, you MUST test the wire(s) with a test light (or some other way), verify the 12 switched (yellow) incase a fuse is blown. Same with the dimmer lead, you need to turn up and down the dash dimmer to get a response from that wire. If you use the wrong wires you will send 12V into the speaker leads from the radio and kill the radio!

When i turn on the cd player the sound from the components vuts off but the sound coming through the subwoofer stays on??

The Sub gets it's output from the pre-amp circuit, whereas the components get their output from the main amp circuit in the unit.

Sounds like it could be a short in the speaker wiring or a blown speaker. Check all wiring to the speakers.

Check all speaker wires from the unit to the speakers.

First check that each pair of speaker terminals at the speaker end is not touching. Or, a wire fell of 1 terminal to rest on another.

Best way to check if it's a blown speaker or a wiring short, is to disconnect all speaker connections ( at the speaker end ) making sure the disconnected wires don't touch each other or any metal in the car. press the reset on the unit and power up. If the unit powers up ok, then its a blown speaker.

Otherwise it's a short in the wiring.

If it's a blown speaker, you can connect 1 speaker at a time and the blown 1 will send the unit into protect mode again.

If it's the wiring, disconnect the unit from the wiring and use and ohm meter to check each pair of cables. A reading suggests a short.

If you don't have an ohm meter a battery and bulb will do. This method usually works on a short.

If you have no joy with either method, take each speaker wire in turn and check with a source of earth (anything metal connected directly to the body of the car, cigar lighter main body when pulled slightly out is good)
