i put two ovn1-4000d amps up to my kicker solo x 12, and it seized after two days of shaking my whole car. rather than buying one of the SPAIR cones, i am just selling the sub and box. i have my eye on a shotgun i want to buy myself for Christmas.
make an offer. amps are still brand spankin' new. sub will be fine once you get a cone for it. the spair cones are for sale all over the web for $150-ish.
also for sale are the two amps. they push hard, and i can show you the sub as proof hahaha.
