Hi guys, This is what ive got going. I have a Rockford P450.4 60x4@4ohms that was running 4 Infinity Kappa 62.7i. I recently purchased a set of Boston pro 60s for my front stage. I bridged the Rockford to get 225x2@4 ohms (stable) for the Bostons but it did not work out to well. I was running my rear Kappas off the HU wich was fine but the amp on the pros was getting way to hot and didint sound much better than running it unbridged. So i need an amp to power the Pros. They are rated at 125rms and they are 3ohm speakers. I want to either get a 4 channel to power my Kappas as well or more likely a 2 channel and run the Kappas off the HU. ( i like the surround sound feel) I was looking at somthing like a Kicker KX 850.4 wich will do 175x4@4ohms, or a ZX 550.2. I have heard about the Rockford 25 to life 150 wich is rated at 75x2 but the birth sheet has it at 300x2. The Bostons from what i hear like 200-300 watts. I dont have a huge budget (300-600$) and i am open to any suggestions. Thanks for any help i get in advance.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ,,,,, Brian
