Amplifier for Audiobahn Bandpass Enclosure?

[PSYS]

Found a decent deal on craigslist for an Audiobahn ABP102J bandpass enclosure with (2) 10" subs...

I looked online and found these specs for the enclosure:

•Sensitivity: 102 dB
•RMS Power Range : 600 Watts
•Impedance: 4 Ohm
•Frequency response: 32-1000 Hz
•Enclosure Type: Bandpass

I wasn't even initially going to start with putting a stereo in my Yaris, but it's a good deal and the guy hasn't had any other offers. I don't want to spend thousands on a stereo system.

I'm hoping someone here at YW could offer up a recommendation for an amp for this enclosure. I don't want the $99.00 Wal-Mart special... and I don't want to spend thousands. But I would like an amp that will adequately power this subwoofer enclosure.

Thoughts?

Thanks!
