I actually have a kicker CompVR 12" (cvr12) an love it in other cars but it's just too much for the z and the size box it requires I just think it takes up way to much room an u need a custom box so it could fit.
that TW3 is perfect I think, plenty of bass and I have plenty more I can turn the gains up without maxing it out.
only down side it it's not ported, gonna look into if I can port it?
best part is how compact an the best part is it hardly weighs anything
