[QUOTE="zako, post: 7561434, member: 629735"] I personally don't like bridging all 4 channels on a 4-channel amplifier. Bridged runs considerably hotter, unless you have an amplifier with large heat sink and/or forced cooling. Since efficiency drops, not only the amp runs hotter, but the draw of the electric current increases. My personal preference among the 4-channels is with the newer generation of Class D amplifiers, such as Kenwood Excelon, PPI Phantom, and Alpine PDX. Sure, they're more expensive, but you get honest +100watts into 4ohm loads, very compact case, and decent efficiency (+80%). However, if you need only two high powered channels, might as well look into 2-channel amps. Parts express sells a 2-channel amplifier rated for 2x150watts for only $99.
