ok, a friend gave me a lil 120w amp by coustic. I know what wires i need but im not sure on which are whic. Where the power comes in on the amp it says, B+ B- , ACC, Remote turn on.
Then there are an orange a yellow a black and red wire coming out. I can tell at one point there was a clip or somethign that held the wires under there lable but no more. Im sure the black is ground and red is power, these 2 are a lil hevier gauge also. Now what are the yellow and orange for and which do i hook up to the remote wire on my sterio and where does the other one go. One last question, what should i hook the power wire up 2 constant power or power when ignistion is on, like maybe tee into the head unit power?? Thanks a lot.

it's been a while since i've been into car audio but...

usually amps are designed to be wired directly to the positive battery terminal (B+, B-). the ACC, i think, would be switched power when you turn the key, and the Remote terminal will act the same way but this will run off your deck, usually there is a blue signal wire coming out of the deck. when the deck gets turned on, it will send a signal to the amp to turn the amp on.

don't know about the orange/yellow. usually on a deck the orange is for constant power ie. memory circuit, always hot, and the yellow is for a power antenna, but i've never seen these on an amp.

good luck,

so... i should get the red wire directly to the battery. The black directly to ground, and then figure out which wire is the remote wire to go to the deck? and then the extra.. the ACC wire would be for.. no clue??

[johnnymopar]

i wouldn't worry about the ACC, just run the blue wire from the deck to the remote terminal on the amp. it's kind of useless to turn on the amp without the deck anyway, right?

ok cool sounds esay enough. One last question, there is a lil switch on the side of the amp that says, GND and then on one side of the switch is says FLT and the other says COM wuts that for??

[mrhford]

That sounds like the switch on the speaker level input side. That means amp can use two different inputs, low level which is just as it sounds the signal is usually no more than .5 volts and is connected with "RCA" plug (round with a pin in the middle).
High level or speaker level uses the signal that would normally go to drive speakers, usually in a normal deck ~ 2.5 volts.

The GND means if the head unit had a + for each speaker and the - of the speaker went to the ground of the body (1960s -1970s)
FLT means each speaker had its own + & - (and couldn't be mixed)
some high powered head units 70s- up.

COM means the right front and rear share a - and the left f & r share their own (not to be mixed with opposite channels)

Hope this this helps!

that helps but now im a lil confused. This in a 1971 c-10. I have Kenwood KDCmp 522 head unit wired to two polk 5x7's under the seat. The head unit has a set of rca plugs for non faiding rear pre amp hook up, I have the current speakres wired up as rears. I have no intention to add more speakers. So I should run the 2 rca calbles, one red one white, from the deck to the amp, set my deck to non faiding pre amp out puts so it sends the signal there, disconct the speakrs from the deck, connect them to the amp, run power to the battery, run a ground, and run the remote wire to corisponding wire on the deck, then what to i set that lil switch that to?? what ever sounds best, or what ever has sound at all?!?! I really appreciate the responces im not good with electricty, and i wana hook this up right the first time, its an old amp a friend got out of his car when he bought it so thats why its kind of confusing about what goes where.
