It sounds like you have a broken output filter inductor in the amplifier. You should be aware that the speaker outputs of the amp are biased at ~40v DC and can give a good shock if you touch the speaker wire while you're grounded (touching the body of the vehicle).


When you connected the speaker as you did, I would have expected the speaker to move in or out and remain there while the wire was connected to the housing of the amp. I'll assume that the amp was screwed down to the chassis of the vehicle. If it wasn't, you may have more than one problem.

I have two kicker cvr 12s how will I hook them up to hit the hardest with a jl audio 500/1

you would want to bridge them you take 2 pieces of speaker wire long enough to reach each sub and connect one side to the box and the other side of wire to the sub then you take your other speaker wire and hook it up to the sub you already hooked it to then run positive and negative to the other sub

you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.

Nine times out of ten if the amp smells burnt it usuallly is. Your best bet is to hook another amp to your system and see if you get sound.

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had

sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.
