Car audio problem

have you recently installed a new radio ? I have knowen people to install radiosincorectly the dim wire behind the radio shows as a earth. however when you turn headlights on this becomes a positive. if you have wired this wire to your sterio this is whyyour dash lights & internal cab light etc keep blowing.. if your wondering why sterio still works is because its earthed through the aerial or mounting bolts.

Hi unbridge the subs and run them sterio your overloading the amp and its going into protection mode. if you have anymore questions about car audio feel free to ask me...

it shouldnt cause it flash the protection light but you are correct in thinking they have wired it wrong ...

the ground of your amp should be grounded to the metal of your car not the battrie ....

System protection unit. They will shut off when turned up too high. If you want it louder, get an amp

this is not a sales pitch but i purchased the correct patch harnass from pmr, it should be available at any good sterio store for about $10

an amplifier needs minimum voltage (usually 6Amps) to turn on. If there is 12V at the input of your amplifier, check the remote for 12V as well as making sure the ground is secured. I suspect based on limited information, that your alternator/charging system is the culprit.Take your amplifier to a local shop and have it bench tested (abuot $10) they will hook up to an independant power supply and verify its properly working. Then it can be eliminated as the source of the problem. Also be sure your wiring and fuse are accurate for the amount of current draw.
Since your protection has never come on, and the power light is going out altogether, you may have an input voltage problem.

the speakers hook to speaker wires not to any thing else no power no negative poles do you have a remote shut off switch connected to amp this would be important to cut off amp

when cut off amp if you still here the humming this can be an indicator of low power being produced by alternator alternators produce 14 anything below 12 would mean replacement of alternator

if alternator fine then you need to find new ground for amp and make sure you have a good ground for sterio this can be checked with a test light
to check a ground all you do is hook gator clip to power then touch test light end to ground on radio end light comes on got a good ground (make sure not to touch any other sterio wires just the ground wire while connected to power to check grounds)
if pulsing in test light on the ground means you have a bad ground
just disconnect move to better ground

check the amp ground the same way as decribed above

Hi , you need to replace with thick wire , if possible attache fuse or circuit trip overload protection you may ask to thew radio store .

yes,pls.stop plugging the system,you may harm your system if you do so,the system has it's own system analysis mode,and if there's something wrong in the circuitry,it will activate,you need the authorize service center my friend,it's a technical problem.

If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.
