I have a Memphis Mojo 4k FS, 4000@1ohm, 2000@2ohm, rms ratings, NOT peak. This is a big amp that puts out big power. It is a used amp also, so it has it's fair share of scratches. Asking $500 picked up or meet within reason. NO TRADES at the moment....will only consider if the trade is in my favor because I will need to resell it.
