Up for sale is one Carvin HD2000 power amp. Here are the details on the amp and the mod taken from the original "for sale" ad. Carvin HD2000. This amp was modded by Carvin to have an input sensitivity of 1.0 V, which allows it to pair with a greater range of bass preamps than most power amps (many instrument preamps do not have enough output to drive typical power amps). This amp is also incredibly light at 9 lbs. Wattage ratings are: 1 CHANNEL RMS continuous - 8 ohms: 400 watts - 4 ohms: 600 watts - 2 ohms: 1000 watts BOTH CH RMS continuous - 8 ohms: 260/260 watts - 4 ohms: 500/500 watts - 2 ohms: 850/850 watts BRIDGED RMS continuous - 8 ohms bridged: 1000 watts - 4 ohms bridged: 1700 watts SOLD - FS: Carvin HD2000 (w/factory bass-friendly mod) and DCM1500 power amps I used the amp to power my backup rig so it so very few gigs, mostly home use. The amp is in good condition and I have never had any issues with it. I paid about $350 USD, I am asking for $250 USD for the amp, shipped within CONUS. Thanks for looking.
