alright i need some real help..... there are sooo many choices of amps out there i cant make my mind up what to use on my new install. Some im looking at are old school Rockford (Power DSM series) O/S Orion (XTR etc) PPI (art series) Zapco, Arc Audio and so on. Now ive used PPI's before and was impressed, had newer Rockford and was ok (so so). After some helpful opinions and advice, also anyone got anything for sale along these lines??? i need 1000watts or more for bass and 150+ a side for my front stage.
