Please help!! car audio sound system,?

Question

k, i got some 800 watt amp, i got 2 12's, and i got the cd player, i have everything hooked up, i did it-lol...

everything was working but then the 12's cut off, i went back there and look and the amp have a red dot, and it says the red dot means protect, i dont know what that means, what do i do to fix it ?

Answer 1

could be the amp man or most time they turn on to red cause the impendance isnt low enough or is too high for the amp. make sure your woofers. are wired right for the amp.

Answer 2

for better assistance, its good if you can provide us with the exact models of amp and subwoofer been used.

why?

some amplifiers are stable only at 2+ ohm loads and 4ohm bridged. there for, if the subwoofers are wired to make a lower final ohm load.. the amplifier will go into "protect".

also, provide the number and ohm load of the coils in the subwoofers and rms watts.

there are subwoofers that are:

1 ohm dvc

2 ohm dvc

4 ohm dvc

2 ohm svc

4 ohm svc

(dvc- dual voice coil) (svc - single voice coil)

with each, there are different ways to wire them and have a variety of "final ohm loads" for the amp... so nothing messes up.

another thing to check is if you have any setting on the amp at max. never have any on Max. also, never have the gain/level higher than 3/4. this will give the subwoofers a distorted signal and will make the amp go into protect and its capable of blowing fuses.

Answer 3

ok first off congrats on trying to install ur first system. ok the protect light is something that guards ur amp from burning, frying. aka messing up. it will come one for many reasons. if you have the positive and negative crossed and touching it will come on. if you had your music playing and it cut off. make sure all ur wires are tight and secure. power and ground. un hook ur amp and reconnect it power ground rca's ect. start fresh so it erases the memory that some amps have. good luck
