Long story short here guys....

I bought a JL 500.1/v2 amp and two 12" JL TW5's from a friend of mine who recently traded his truck in for a new one. He no longer wanted to keep the system so he sold it to me for a few bucks, 350 to be exact. It was a steal, so I couldn't pass it up. He got the system installed at a local shop. He doesn't know much about car audio.

When he was removing his stereo at the dealership, he had to cut the amps RCA connections because he couldn't unplug them. They were "hand-built", so they weren't out of the box connections. The RCA's still cannot be removed from the amp. Is it possible they where glued or crimped on? That makes no sense to me at all, but is it something that is an industry standard? If so, how do I go about removing them? Thank You!

Try using pliers and rotate them, being careful to turn in such a way that you won't twist off the RCA output connectors on the amp.

Right on man. They came off. Any idea on why they were so tight fitting? Is that normal from a man made RCA connection?

Better quality RCA connectors ARE tight - they're supposed to be...

I expect the age of the connections just made them settle in, some small amount of oxidation might have gotten in there, or possibly even a soda was at one time spilled... Any number of things might have happened.

Got ya. Thanks for the help man. No signs of any liquid damage on the amp. I believe it was just a little of the tightness and the oxidation that was holding it in place.

I purchased a MONO RCA for a home theater SUB and it had a "tension nut" on the connector. One you plug the RCA into the sub you tighten the nut down and it squeezes the connection onto the terminal.

Took me a bit of time to figure out why I couldn't get it on there at first, had never seen them before.
