If you are on a budget,I would recommend you checking the classifies out on the forum,and or the bay.I like the old school Autoteks/Hifonics vii,viii series..But a USA US Acoustics seriesII 2150 thats up in classifieds i have,4ohms stable amplifier should bang nicely!!, to run in a 4 ohm operation/8ohm,if you decide to run in a 1ohm load.. there are sevearal choices to be made like the Orion HCCA series,HCT amps out there.Zed made amps are a remarkable choice IMO of course.Everyone has an opinion to what amp to use,but in the end,its what you want,.Just be sure to compare the specs of the amplifiers performance, and get the best bang for your buck!
