You can also plug that cable to any positive wire adding a switch of course. the only problem... don't forget it on, it will eat up your battery if left like that unless the positive power source is canceled when removing the key from the car.

Hey i dont know to much about amps, but me and my friend (he knows a decent amount about amps) would plug the power into the amp and the green light would come on. Though when we plug it into the subs, the...

Are you connecting positive to positive and negative to negative from the sub to the amp? If so, try positive to positve (+) in the far left channel and then the negative to negative (-) on the far left channel to. If no luck do the same in the other channel with one sub at a time. Try one sub at a time, Dont try an connect 2 or more subs to one channel as this would cause the amp to go into protect mode (red light you describe). Usually the positive wire has either a line down the wire, writting on it or has a red seperate wire with it when wire end stripped to connect it. Hope this helps and please rate...

I have this hooked up and works fine with the key on, but when i start the car, sub light, amp and sub dont come on.

You have connected it to the wrong power wire - one that is only active in service mode - first key position.
You should draw a wire directly from the battery (don't forget to add a 40 amps fuse on the wire) to the amps. If you don't want them constantly operational (you will have to manually shut them down) install a relay on the wire with the command coming from a wire from the instrument key position - second position of the key. Use a voltmeter to identify the wires.

I bought a 500/1 jl audio amp and also a w7 10 sub

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Amp on but no sound from subs

Make sure that you have a good set of RCA cables. Then make sure that you have 14 gauge speaker wire. As for amp make sure that you use 8 or 10 gauge wire. Make sure you have a good GROUND.

Something Wrong With my Fosgate 500-a2 Amp

Is the amp being fed directly from the head unit's RCA preamp outputs or is it being fed by another amp's preamp outputs? Try temporarily wiring up a speaker you know is good in place of the sub and see if anything changes.
