hey tony, i've seen the db drive amps like you want in competition ,eeh ok i guess.heard mixed feelings on the planet audio amp,some same great for the price and some say not so good.personally if i were you ,i'd just look at ratings .the planet audio looks ok but i cant find any efficiency ratings ,which concerns me.100 db rating is pretty good tho.but i did find an efficiency rating for the new db drive okur ams at 85% at 4 ohms which is good.me i'd get the db drive i think.planet audio amps just dont seem to do anything for me,thats if i had no other choice .
