I know I've been starting a lot of threads lately... but I had to share this. This is my boat (24' Jaws Lorequin race boat) with the new stereo I put in. It's not even half way turned up... and with the amp and speakers I'm using... I can turn it all the way up with NO distortion (except the pain in your ears). They are Paradigm speakers hooked to a Zapco Competition amp (2 ohms [bridged]) and a cheap Clarion head unit. Just to give you an idea of how much power the amp is drawing... it requires 4 gauge wire!
