[QUOTE="zako, post: 7743082, member: 629735"] I'd recommend PPI Phantom P600.2. It's a 2 channel amplifier that gives you 600watts RMS when bridged with 14.4V. Should your voltage drop below 14.4V, it will still provide more power than you need. Or even better, get the PPI P1000.1 mono block. I would not spend money to buy even more cheap and overrated garbage. Besides wattage rating, the cheaper amplifier can have other problem issues as well. If heat is your concern, get a modern Class D amplifier such as the PPIs are mentioned. (Your Sony appears to be a class a/b amplifier. A/B amplifiers waste more energy as heat). They are already a value leader IMO, with PPI P1000.1 sold for like $170-$180 on sale online. Go a little below that price and you have a good chance to end up with crappy hardware. Also, I am not sure what the extra 100 watts will do to you. That's ~1dBs of difference in SPL. If you want to feel an audible difference, I'd say double the power you have. Regarding the Hifonics amplifier, it's probably better than what you have. However, personally I wouldn't buy any of currently produced Hifonics or MB Quart mono blocks.. It's a long story, but I feel they're inferior products if SQ bass is the goal. [/QUOTE]
