I have a custom 12" sub for sale or trade. The sub has a four spoke basket, dual spiders, 3" 4ohm voice coil, and a chrome motor from a DC lvl 3. This sub gets loud and low. Sounds good in sealed in ported boxes. I had it in a 2cf boxed tuned to 33Hz and it sounded awesome on 600wrms. Im looking to trade it for an amp that does 1500 watts rms @ 1 ohm, or some 1/0 gauge wire. Maybe even another sub or a battery. Only thing wrong with the sub is it has a few ugly spots on the cone, but they dont affect performance at all. I can send pics if you want. Email me with offers. Thanks.
