How do I tell if my RCA's are dead?

I installed my system,worked fine. Played nice for a week or so, then randomly will cut out. Ill move the RCA's and then a bump will happen from the sub,and when I move the RCA's just right,the sub plays,otherwise it wont play at all.

I dont think it has to do w/ my power or ground,the amp stays on all the time and has yet to go into protection. Im running it at 1.5ohms when its rated at 2. It DOES get hot,not hot like my hifonics,but definatly hot.

I think its my RCA's. What do you think?

Also,the sub will randomly play sometimes,and then cutout,and randomly Ill hear a BUMP from it, trying to play a song. Ive turned the sub down and I dont know what to do.

 
There could be a break somewhere in the cable ,if u can unscrew the connector sleeve then check inside there for possible break.I had the same problem(turn-on thump),found the problem,soldered it,no more thump.I ordered the RCA's too short(miscalculation) so I would pull on them and I believe thats what caused the break.

 
If you have a voltmeter, remove both ends of the RCA's and check the resistance. If there is some small resistance, you're good. If it says "1" or the infinity symbol, then the RCAs are broken or loose internally.

It sounds like it might even be the RCA terminals on the amp. Do they wiggle? That is very easy to fix with a couple of dabs of solder.
