They use very very low quality components that pick up RF noise easily, just as said above, make sure you grounds are perfect.
Also, id like to add, those amps are MAJORLY over rated, you'll be luck to get 240 watts rms out of it, yet alone 2400 lol.

Yes, better RCAs will often change your status from rookie.

But then again, using Lagacy and wuestions like your are, it may not work.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Goody you are correct in assuming the problem is with the RCA.  You have a burnt trace on the circuit board of your amplifiier.  If you can tell me which speaker wires are the bridge wires I can get your amp working for you.  Is bridge Left positive and Right negative?  Or are they Left negative and Right positive?

I get 216WPC RMS. 150 dollars for 450 watts, SHIPPED! A good buy, that was! 50A Max current draw, and Class A/B to boot!
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
