kl0wn Posted February 2, 2010 Report Posted February 2, 2010 Have you done the big 3? If not, go do the big 3 in 1/0 wire. That should help out a lot. If it's needed, throw an extra small yellow top in the back. 06 Mini Cooper S Sundown, SoundQubed Cadence, XS Power 151s Sealed 155s Outlaw Windshield @ 37hz
