2) NEW BOSS SK652 6.5" 300W 2-Way Full Range Phantom Skull Car Audio Speakers
just hooked up 4 of these in a speaker tube I built out of 6 inch PVC pipe with a Clarion marine 1410 amp I think it was and they sound great.  Not a real heavy bass speaker but enough for good clear all around sound.  Plays everything from Shinedown to 2PAC and set up right no distortion.  Very happy with the build so far
