I am looking at a arc xxk4050 amp that is a couple months old he wants 300. for it. Is that a good price? the sheet says 118-120 watts a channel. I have heard a lot of good things about arcs but never heard more than a couple minutes in a demo room

That seems like a really good price if the amp is in good shape. I emailed arc and here were the factory direct prices on some other xxk amps.

1500-XXK $689

2100-XXK $409

(plus $30 shipping).

that is a good price.

yup, good price.

ok thanks for the price on the other amps I aleady looked up the web site. that is a good price on this amp, but I dont think I could get away with that much for my sub amp. so I would need to get another brand, and I really wanted to have matching amps. But SQ with a litttle LSQ is a higher priority to me. so If I use that to bi Amp my mb Quarts what wire should I get? Right now I have 16awg Monster XLN with the crossovers up front and was thinking some sort of 14awg 4 conductor wire.

also I haven't checked But those numbers a probably @ 2 ohms correct
