[QUOTE="Water Bear, post: 8604480, member: 673826"] So I've been looking at class D sub amps around the 1k-1.2k watt mark. I've looked at everything from Zed and Zapco to mainstream brands. (BTW Zed has some really great articles on [URL="http://www.zedaudiocorp.com/techtalk.html"]his blog[/URL]). So here's the JL Audio HD series (yes I know they are way over priced): [URL="http://www.jlaudio.com/hd1200-1-car-audio-hd-amplifiers-98250"]HD 1200 watt amp[/URL] The relevant specs: S/N @ rated power: >110 db S/N @ 1 watt: > 79 db Damping Factor @ 4 Ω: >500 / 50 Hz Damping Factor @ 2 Ω: >250 / 50 Hz THD+N @ Rated Power: And then there's the Alpine MRV-M1200: [URL="http://www.woofersetc.com/c-3-amplifiers/c-27-one-channel/alpine-mrv-m1200-monoblock-1200-watts-rms-class-d-amplifier.html"]MRV 1200 watt amp[/URL] The relevant specs: Signal to Noise (Rated Power into 4 Ohms): >105 dB Signal to Noise (1W into 4 Ohms): >85 dB Damping Factor (10W into 4 Ohms at 100Hz): >750 Now the THD is not listed, but it's So please explain to me. Why would I pay $584 more for the JL when the cheap-o Alpine has incredibly similar specs. And don't say balanced inputs, because Stephen Martz says that doesn't matter much in car audio. [/QUOTE]
