Is Quantum Audio any good? I found this amp on craigslist, guy is asking $150 for the amp, Quantum Audio Cozmic Series QCA2500D * 1 x 1250 RMS @ 1 OHM * 1 x 2500 watts peak @ 1 ohm * 1 x 1250 watts peak @ 2 ohms * Top of the line Components * Heat Management System * Built in sub-sonic filter * High Efficiency Mosfet Power Outputs * True 1 ohm stability (other brands write 1 ohm, but when you run them at 1 ohm the amp flips to protect constantly. these are true 1 ohm stable!) * Built in Low Pass CrossOver - adjustable at 12 dB per octave * Bass Remote Control * Class D * frequency response: 20-250 KHz * THD: .05 % * S/N Ratio: Greater than 95 dB * Input voltage: 11 - 14.4 volts * Adjustable Input sensitivity: .2 MV - 5V * bass boost control @ 45 hz - 12 dB * dimensions: 12.6" x 2" x 10.9" inches I got two dual 4Ohm Alpine Type-R 12" subwoofers, they are rated 500 watts RMS, so with these subs wired to 1 ohm, then this amp should slap them insane right? I just dont wanna buy it if it's complete junk
