I'm selling two Taramp's DSP3k 1 ohm versions. They've been installed for less than a month and are in pristine condition. These are the newest Taramps and are much more sturdy. They have an onboard voltmeter, clip indicator, flat response down to 8hz, a clipping limiter (set it to 1% or 10% THD depending on your tastes, turns the amp down instead of clipping!), lots of crossover options, and tons more features and improvements. They're also a lot smaller than a Korean 3k.
I'm asking $450 shipped each. They still have over 10 months left on the warranty. I'm only selling them to upgrade to a larger amp, probably a HD10k
