When you push it back, the break is not going to be at the board.  It may be at the bottom of the rca jack.  If it does not push back far, it may not be broken.   If you have an ohm meter check for continuity from input shield to output shield.  when checking push the RCA like you did earlier if it does not show a dead short when you push it, it is broken.

Okay so I don't think the amp has the problem anymore. I checked the RCAs for continuity and they're fine.

I took my old amp which works fine and hooked it up --- exact same problem.

So, any suggestions on what the problem may be?! I'm going to check my power/ground/RCA cables for continuity, but I'd like to know if anybody could give me some suggestions.

Thanks again!!

and the story goes........

Little Tony raises his hand "I know, I know the answer"

Mrs. Screechy Speaker teacher,  "OK, Tony....whats the anwer?"

Little Tony sayes "When the RCA's pulled out of the amp, the center post touched ground, & blew out the unprotected outputs on the Pioneer deck!"

"Very good" Mrs. Screechy Speaker teaches sayes

LOL....it's the deck dude.

used to be loud, used to be fast...now I am married LOL

Okay, thank you for the answer, minus the sarcastic dialog.

But, if it is the deck, shouldn't the alternate grounding thing have worked? When I grounded the RCAs to where the deck is grounded??

Oh yeah, also, when I reconnected everything, the problem didn't happen.

Then I replaced my amp and closed the trunk, and then BANG it happened again. I think it depends on when I move the amp around, that's why I don't think it's the RCAs on the deck... could it be the ground or power??

Ok,

So the problem happens when I play with the RCAs at the amp. If I push on them, FULL BASS occurs, if I wiggle them around, it works like normal.

Now, you'll probably say it's my amp, BUT I tried another amp that I know works, and the exact same thing happened. So then I thought it was the RCAs, so I bought new ones -- same PROBLEM!

I am totally confused now and out of ideas completely!

If anyone could shed some, ANY light on this, it'd be greatly appreciated!!!!

CASE CLOSED!!

I finally took it apart AGAIN, and knowing that I can't really break it further (plus I only paid 40$ for it from eBay), I took apart the RCA inputs further because I could only see 2 of the 3 connections to the main board for the Input and the Output RCAs.

Lo-and-behold the one solder connection I COULDN'T see easily was BROKEN.

So I massacred my amp and finally got the RCA housing off of the board. I soldered the broken piece back together, but in the process I totally messed up the RCA outputs, but I won't use them anyways.

So, I hooked everything back up and my amp is working great again! :D Yay!

Thanks to everyone, you guys were right all along. Much appreciated!
