You need to wire the ground wire first, because this will make sure that the amplifier doesn't blow when you connect power. Your power cable comes last. First do the ground, then remote and follow with the power. Make sure the ground is attached to the body of the car properly, otherwise you will get poor sound

Don't know how to hook up the amp. It came with a wiring kit and I have no idea on how to hook it up.


You need to connect the Power wire (Most likely red wire with fuse) to the battery and run it to where you put the amp. You need to also drill a whole in the car and make sure it is grinded up and bare metal is shown. Screw the ground wire there with a bolt and nut. You will then need to run the rca cables from the amp location to either the back of the headunit if it has RCA outputs, or use a Line out converter, you can get them at best buy. Then you need to find your cars wiring harness code and figure out which is the remote ignition turn on and tap into that and feed that wire back to the amp to turn it on. Hook all wires up and make sure power and ground DO NOT TOUCH.

I wanna put it into my car myself but dont know how and was hoping for a lil instruction


you will need a amp install kit witch comes with a 15 ft patch cable power line for amp and a blue line for remote. these wires run from the radio to the amp. The blue wire is called remote it turns the amp on or off depending on the radio state. the patch cable is rca jacks on both ends the back of the radio should have the female part of the rca jacks hanging from it. The other end goes into the amp. and last but not least the heavy red wire will go from the battery to the amp usually there is a fuse holder that you need to put between the battery and the amp. As far as grounding just ground the amps negative to the car chasis some where.

Good Luck Hope this helps

Wont turn on i bought it though craigslist


well this is what you do to check it to see if you bought a blown amp.
wire it into your car and then take a digital volt meter check to see if you have power and ground and remote turn on .


take the red lead and put it on the battery wire at amp and the black lead to the ground then see if you get 12volt to 14.4 use the amps ground for the black test lead if nothing you may have blown fuse or bad ground.

check the remote wire same way as about if you get 12 to 14.4 volt it works if not could be blown from radio or bad ground

checking the ground put the black meter lead on ground wire and the red lead on 12 volt power source if nothing a bad ground.

if your get voltage on the remote wire and battery wire and have good ground then you need to call the seller and get your money back ..

Amp


you want to put a 30A into the amp and the inline fuse that you put onto the wire should be greater than 30A but not too high for what the wire is rated. The best bet for wire is to buy a wiring kit which comes with fuse holder, right size fuse, wire for main power ground and remote. You may want to double check what is written on amp for the size to put in there. Technically you can put a 100A onto the wire if it is big enough and the fuse on amp will protect the amp from problems. Hope this helps, Good Luck

I am trying to hook up an ancient Kenwood KAC-801 amplifier. The original input cable has 1 red, 1 black, then another smaller awg white (1) sharing a common with another small awg yellow. Applying power...


Yes, keep in mind that the amps have a constant power (the large red wire) and need a remote signal to tell them when to turn on/off. This wire connect to a switched 12v from the ignition or radio blue wire (if aftermarket)

Need help in installing amp.


depending on the power consumption of the amp u will need to run a 4-12 ga wire to the positive battery terminal. then u need to ground it with a wire connected to a clean ground like a chassis bolt. next u need preamp outputs on ur deck to send audio signals to the amp. lastly u need to hook up a remote wire to the blue wire in ur cd player harness
