[QUOTE="keep_hope_alive, post: 7468689, member: 576029"] agreed on external amplifiers for speakers. head units don't provide enough power for aftermarket speakers due to a substantial reduction in sensitivity. i don't buy or recommend 2 channel amps due to low resale and limited flexibility. i only recommend 4 channel amps. the aren't much more expensive and they are much more flexible. the right 4 channel amp can even run speakers on CH 1&2 and a sub bridged on CH 3&4. you need to coordinate the sub impedance with the minimum bridged impedance if you go that route. but i do agree that your best bet for a sub amp is a monoblock Class D. something efficient that can give the sub plenty of power. a dual amp setup isn't that difficult to do, but it does require a fused distribution block and more effort with mounting and wire routing. these simple dual amp build logs may help you as well: [URL="http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1625041/page/1#Post1625041"]http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1625041/page/1#Post1625041[/URL] [URL="http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1400581/page/3#Post1400581"]http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1400581/page/3#Post1400581[/URL] [URL="http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1755977/page/3#Post1755977"]http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/1755977/page/3#Post1755977[/URL] [/QUOTE]
