System Isnt Working :(

[SKYL1N]

i hooked up my amp/subbies today

and the amp wont turn on

i have the cable from battery to amp via a fuse

an earth from amp to bolt in car boot

rca cables all connected

remote controll connection connected

i start up the car

amp wont turn on

chance of a faulty amp perhaps :S?

Most likely to be either your fuse or the remote cable is not passing 12v to the amp.

Check that when your head unit is powered up you have 12v between that cable and your earth point

When I hooked up my amp and sub it was working fine. Went for my first drive with it in and it was cutting out every now and then. I checked the fuse for the amps power wire and the fuse was a little loose in the holder at one end. I was able to just squash the ends in and now it bites down hard on the fuse and haven't had a prob since.

I have a similar issue at present.

I have a Kenwood KAC-8103D 1000Watt 2 channel amp and i can't get the thing to start when the headunit turns on.

Heres the weird bit;

I work at a school so I have access to cool stuff in the science lab like 12volt power supplies. I hooked one of these up the amp and then bridged the power and remote together to get it to switch on. The power led flashes. Hooked up a voltmeter (cheapy science one but does the job) and it sits ib about 11-11.5 volts when the light is on and then jumps up to 12.5 volts when the light goes out.

Thinking this was strange, i went and got another power supply and connected it directly to the remote wire and now the power led stays on solid. I dunno how I am going to overcome this in the car as there is only one power source.

Something else that got my attention is that the amp WILL NOT run when I set the voltage on the power supply to 12volts or 10volts, and will only run when the power supply is set to 8volts... Also the amp will turn on when the remote wire is set at 2volts.

I think my amp may be playing silly buggers with me, but thats what i get when I buy the amp from a pawn broker.

it also does strange things when you do not have the current to run it..

so what can i do to fix this problem?

so what can i do to fix this problem?

1. dont go thru pwn shop again

2. check fuse and cable from battery to amp.

3. save some money and get it installed by someone who knows what they r doing.

I dont think this is a fault amp, but hey i could be wrong. Id check to make sure that your earthed correctly. If that isnt the problem id check to make sure that there is power getting to the amp. If that doesnt work, check the fuse. If that dont work go to the place where u brought it from and get them to install it. Also read ur warrenty... little tip.

hey man, have you tried connecting a manual switch to the amp instead of running the singal through the remote wire just run a manual switch that can be turned on manualy by yourself.. and see if that works.

Check its not shorted somewhere. One or more wires could be touching each other

Also check you have the right wiring kit (If it's a powerful system you will need a 4 gauge)

Ok, hooked the amp up just to power and bridged the power and remote to turn it on. And still nothing. Amp flashed and made a ticking noise. Then the light started blinking more rapidly without the ticking noise.

Moved the earth to the another point in the car, where the battery is also earthing to so i don't think its an earthing problem.

We also tried the amp in a working setup and had the same issues.

*Never buys amps from pawn broker again*

Also, not quite sure on what gauge of wiring is there. There is one big thick one running from the battery into a 2 distrabution block (to power 2 amps) and the wire from them is a bit thinner. Same wire I have seen used in every other system i've seen
