Mini - Arc Audio KS mini 500.1 sub amplifier, $225 shipped
Retail price for this amplifier is $400 to $500. Since mine is not new and has a few minor scuff marks, I will ship it to you for $225 if your address is within the CONUS or overseas military (APO). Anyone else, add an extra $20.
This amp is a little pricey for the power, but this is a high sound quality Class G/H unit that is so small it is often marketed as a motorcycle amplifier. The size (or lack of it) will give you the widest range of installation options for your Corvette.

I used this sub to power a 13" Boston Acoustics SPG555 subwoofer at 4ohms (300W) and it was plenty loud enough for me.
I found a good deal on a matching set of JL Audio amplifiers that better suit my system, so I'm letting this one go to fund other projects.
