    Need more info to better troubleshoot. What size amp (look at the outside fuses and give me a total) Where is the power wire ran to, the battery? How about the ground wire. Ran to where? Did you get a GOOD ground? Metal to metal? Hit me back. Thanks.

A 2nd ground isn't good unless it's the same guage as the 1st and it's grounded AT THE SAME POINT as the 1st one. Did you check the voltage at the amp? I wouldn't trust your dash gauge as I've seen them report a unreliable display under a load. I hope you're in good shape now. Booming season is fast approaching lol!

75% of the time all you need to do is reground the ground wire. If you don't have a sturdy ground it can't complete the circuit. Make sure to grind off the paint so you're grounding to bare metal. Also, make sure your ground wire is the same gauge as the power wire or larger than. That should do it.

How to connect wires to amp


Most amps have 3 places where you need to hook up wires to power them. the 1st is a ground wire that at best is 1 foot long and it goes on the ground or negative 12 volt connection then a bolt on the car you may need to sand off the paint for it to work, 2 a RMT or remote wire that is normally in the middle of the power and the ground connections the remote turns the amp on and off so it needs to go to the remote wire on the radio or a ignition spot on the fuse box - turns on with key on and off when you turn the key off , 3 the power wire is hopefully large 4 gauge wire and goes to the + 12 volt plug on the amp this wire has a in line fuse and goes to the battery and to the amp only. RCA wires go from the radio to the amp and are round and just plug in with no screws some factory radios need a conversion kit you can get at walmart for RCA wires. the speaker wires have some sort of mark or line to tell you what to put were like if you put the line on a negative on the amp you need to put the line on the negative on the speaker box to or it will not bass and could hurt your amp. ask me if you need anything else :) and please rate :/

I have a 1400 watt cruch amp & i hooked it up myself. when i turn the radio on the power wire on the amp comes on, bt if the audio cords are hooked up, the protection light comes on. if i dnt hook the...


Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.

1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.

2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.

3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.

Need to install a cdplayer in 70 chevy truck?


Because of the year of the truck you will not have any wires pre-wired in the truck, go to a Radio Shack, car audio store or Best buy and buy yourself some speaker wire for vehicles, about 5 ft of 14 - 16 gauge yellow wire, 5 ft of 14 - 16 gauge red wire a couple of 10 amp fuses and 5ft of 4 gauge black wire.

You are going to run the Yellow, Red, Black wires together from the radio space where the radio sits in down to your steering column, the speaker wires will go to your speakers from the radio, a + and a - lead to your speakers and connect them as needed.

Now back under your dash you will connect the yellow wire from the radio to the 12 volt + wire under your steering columns 12 volt power wire with a fuse inline, if you hook up a test light to this wire it will light up the test light without the car switch being turned on, the red wire will hook up to your ignition switch wire and your balck wire to the vehicles ground chassis, basically ground that wire to a non painted surface of the vehicle. This radio needs to be hardwired like I explained.

Good luck and hope it helps.
Lex.

I have two amps one for my speakers and the other for my subs it was working fine but recently one of them turned off. I thought was a short circuit and bought a new one but still doesn't work. Its looped...


When running multiple amps you need a relay most of the time for the remote wire off the radio this is because the radio was built to power one not multiples. one 12 volt relay may help .check local car audio store. also when hooking up relay it has to have a 12 volt power wire connected to it usually the center pin on the relay is your connection for the power wire the you connect your remote wire from the radio to the relay then connect each amp independently to the relay. Hope this helps write back if not . and if so leave feedback

Wont turn on. everything should be connected properly, got new fuses to make sure. It worked fine until i dismounted and disconnected it from the battery. When i reconnected it, no luck it is a Autotek...


Make sure this high powered amp is not mounted directly to the chassis of the car. Mount it to a wooden board and you can screw board into the car. Because some very high powered amps can arc and damage itself.

Next make sure the tubular fuse in the hood is not bad it may look good but internally it got real hot and caused a bad solder connect in the fuse. You can test it with a meter. Measure one side then the other side if the 12 volt is going thru the fuse.

Next step is now you know your amp is getting 12 volts from the car battery but do you know if your amp turn on signal is turning on the amp itself. This is a easy test get a little wire and jump the 12 volt to the amp turn on wire if the amp comes on then you have found your problem. The amp turn on voltage is too weak were ever youve connected the signal. Normally you hook it up to the blue/white wire on the back of the radio first. If it doesnt have one hook up to the blue. Now on some very rare occassions the voltage drops when you put a load to it and is not enough to turn on your amp you can easily see this if the voltage across the blue wire goes below 12volts so hook it up to the red ignition wire so at least when you turn on your radio the red will send 12 volts to the amp to turn it on and will not drop in voltage. You see that wire has to be 12volts when it drops the amp will not turn on. Same with the battery Voltage you have to maintain 12 Volts or higher for the amp to operate.

My Kenwood KAC 9152D Amp is hooked up to power and wont turn on.No light no nothing. Power going to it is good though.


Check your ground. Make sure you sand off any paint where you grounded the amp. Also did you hook up the remote wire? It's the blue wire on the back of your headunit. Some say remote wire, others say power antenna either one will work. Sounds like one of the two...hope this helps.

My radio stopped working after hooking up the amplifier


Did you double check your work? Did you check the resistance of the fuses? Just because the fuse appears to be good, it can still be blown. Do you have access to a multimeter? You need to check and see if the head unit is receiving 12 Volts continuous which you put the multimeter probes to the black wire and the yellow wire. Then connect the probes to the black wire and the red wire. This wire should only have power when the car is cut on. If you are not getting 12 volts to these points, the problem is your wiring system somewhere...probably a fuse. If you are getting 12 volts, your head unit is garbage. I want to say it is the fuse.

Power wire volts go down when turn the car on


Is the power wire going to the battery? Is the ground wire short (3-4 ft) and connected securely to a GOOD metal groun source? Are you using an AGU fuse holder at the battery? Reason I ask these questions is you migh have a weak connection somewhere or a bad fuse that looks like a good fuse. When the amp is turned on, it requires more amperage that at a standby mode. Hit me back.

When i hook up the remote wire it makes my power wire go to 4 volts


If the battery is strong enough to start the engine, you probably have a bad connection or a defective fuse in the power wiring. If you solve the voltage problem and the amp blows fuses, it likely has shorted output transistors.
