I have 4 polk audio RT 3000p's and 3 of the subwoofer amps don't work properly. Instead of spending the $ to get them fixed, I was considering running my 2004 re audio xxx 18. It's a D4 ohms sub so I'd like a amplifier that can put out a good 1000rms at 2 or 8 ohms. I can build and design an enclosure for it.
My question is what's an efficient and decent SQ amplifier I can use?
I'm somewhat new to home audio. What's a good price to sell the rt3000p amplifiers for on eBay (they will help fund my amp). Amplifiers turn on but 2 of them make a humming sound and all 3 of them cause the subwoofers to produce an annoying cracking sound. Thank you for all the help, Joseph.
