amp question

[pujo]

hello to all. just a quick question. what powers up a car amp? is it the red * gauge red wire that connects directly to the 12v battery?

cheers

1.Lick your finger a couple times

2.Start your car

3.Expose the RED wire with a knife

4.Lick your finger a few more times

5.Touch the exposed wire

6.Get electrocuted and fried

:D

lol

But srsly don't you have a multimeter check for voltage on the wiring should be around 12v

Amplifiers have three power terminals.

Gnd -- heavy cable to cars body (negative)

+12v -- heavy cable to battery positive (Please use a fuse near the battery).

Rem -- Remote trigger, +12v.

The 'gnd' and '+12v' are the main power source for the amplifier.

The 'rem' is a low current signal from the headunit that in affect tells the amp to turn on.

Same as the wire for electric antennas on most cars/radios.

Does this answer your Question ?

If not I can get much deeper into the tech side of it for you.......

Its usually red.. And if your amp has been pre-installed it should be attached to the Power/+ terminal on your amp.

Use a multimeter, quickest way to find out if you're not too sure.

thanks guys. the reason why i asked is that my amp stopped working. i found out that its not receving any power. there's nothing wrong with the amp because i tested it on another car and it works. i couldn't really figure out what was wrong. i bought a new power wire to replace the old one and it still doesn't power up. i checked the fuse and its still fine but no power. the ground connection is fine. no clue at all.

check your remote wire. if its not hooked up right, your amp wont power up

Not receiving power - on what wire and how did you check this ?

Which fuse and how did you check it ?

Crude test, disconnect the remore wire from the amp, use a short piece of wire and (on the amp) join the main power cable and remote connections together.

If it turns on you have a bad remote signal.

If it doesn't turn on you either have a bad earth connection, or the main power connections/fuse is faulty.

Also possible is a speaker wire short that is tripping the amp into protection.

Number of times I've had people say the fuse is fine and yet it wasn't is staggering.
