This is my 12' Insignia Subwoofer that I built with two of my other friends. However just recently (2 months ago) I bought a 500w Bash Amplifier for it instead of using that big 600w one. It is much more convenient when the amplifier is built in. So, here it is. Tell me what you think. Check my other video for all the other facts concerning this subwoofer. Sorry that my camera had some issues focusing. The amplifier was on sale for $164 and is really good.
