im sure im gonna get eaten alive for this but i really only recommend products ive used or experienced for more than 5 min. my good friend and i installed this amplifier in his car and spent the following weekend on a mini road trip. the Soundstream REF4.760 really impressed me, im thinking about using them or the new ppi power class because i believe the amps are designed and built pretty much the same. the front channels are pushing a set of boston spz60's and the rears are bridged on a boston G5 12 vented. i wanted to listen to all of my music over again.... i was really impressed with this amplifier. i know its a little over budget from woofersetc, he purchased his off
ebay for under $300 shipped.
