id try posting in "Wanted" in sales section. probably get better response. im running a Lanzar 2000 watt amp, class D, and i got it off ebay for like 150. thats what id recommend for ya. check out ebay.
its a Lanzar HTG2600D I believe. it does the job well. i have a crappy non-spec built box, running a RE 15" sub, untuned, hitting right at 130 dBs. it does 2000 watt max, 1000 RMS, and is 1-ohm stable.
