alright i just found a rf amp. the rf power 450S. its got some good stats and @ 2 homs, it gives 225W. i was wondering if i should get this or a jbl 600.1 to power TWO blaupunkt pcwi1200 subs. ill run it in parallel for either one i get to get max power in a 2 ohm load. which is more reliable, longer lasting, colder? any info please!
