you made the mistake because other people ASSUME subs don't need amps, and because you ASSUMED he was running a powered Bazooka tube. you're statement of Bazooka has built in amps is totally not relevant because the OP could be correct in saying that he has no amp and has 2 bazooka 8"s because they make just subs, and loaded enclosures, and then they make self powered enclosures. if there is one thing i've learned in the years of doing this, don't assume. if he said no amp HE assumes no amp. we both know he has at least a little amp in the HU, but really...don't jump down his throat.
