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

Installin car systems


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.

You should really invest in a $15 wire harness so you do not have to cut the factory plug.
Instructions will be in the package - but in the event you dont have a factory plug due to theft - here is the vehicle's wiring color codes...

Car Radio Battery Constant 12v+ Wire: Light Green/Pink
Car Radio Accessory Switched 12v+ Wire: Black/Violet
Car Radio Ground Wire: Black
Car Radio Illumination Wire: Light Blue/Red

Car Stereo Antenna Trigger: Blue

Left Front Speaker Positive Wire (+): Light Blue/White
Left Front Speaker Negative Wire (-): Orange/Light Green
Right Front Speaker Positive Wire (+): Dark Green
Right Front Speaker Negative Wire (-): White/Light Green

Left Rear Speaker Positive Wire (+): Tan/Yellow
