I am buying this subwoofer new for my Yukon because I know it is among the
best you can buy, and it is the type and power I am looking for for my
car. No I am not running any other subs, and money IS an object for me, I
just wanted to get the point across that a good price isn't first priority
here. In agreement with winkenstein (DO NOT cheap out on an amp for a sub
as beautiful as the W7 line.), quality is my first concern after the
investment I made on a good sub.
