VERY good sq sub. Had one in my dads van til my mom *****ed him out about it lol
Added nothing but clean low end off of 200 watts rms. Blended perfectly with his stock front stage and got down on james brown and grand funk (dad's an old school pink floyd head--he even has the original dark side of the moon lp).
If i had a need for it i would buy it. Can't beat that price!
