[QUOTE="trumpet, post: 8500542, member: 628688"] This is a heavily discussed topic that's likely to open a can of worms, if anyone sees this subforum. Usually people will want one pair of mid-woofers and one pair of tweeters up front in an "SQ" system. Each speaker will have it's own amplifier channel, which means this needs at least 4 amplifier channels. A subwoofer is necessary, so that requires one more higher power amplifier channel. It looks like you already have a good start. Instead of going directly to changing your amplifiers, let's look at the equipment you already have. What model are the Infinity speakers? Did you change the radio? If yes, what brand and model is it? Active 6.5" component system, 150W x 2 for the mid-woofers, 100W x 2 for the 1" tweeters. Basic aftermarket head unit in the dash going to an 8-channel digital signal processor which then goes to the amplifiers. The DSP is where a lot of massively audible sound quality improvements come from, but the car has many, many hours of labor and several kinds of materials to improve the acoustics as well. [/QUOTE]
