[QUOTE="Scott Harris, post: 203297, member: 1861"] I went from 2x PLX3002 to a single Crest ProLite 7.5 driving 4 Growlers. I had run the PLXs bridged with one 3002 driving each pair of Growlers, but found it was better to drive them as 4 separate 8 ohm loads with dedicated amp channels. I switched back & forth a couple times to make sure and it was noticeable. Upgrading to the ProLite 7.5 was much more noticeable difference in output on top of the best config with the PLX's. There was also a noticeable change in power consumption with the class D design of the ProLite being much more efficient and apparently being more tolerant of low voltage and it has never reset in a situation where the PLX would reset.
