Built for pops and fit perfect until he did some upholstery work. Set up for Tang Band 1139si tuned to 35hz with Aero port. Woofers are not included since they will be reused unless price is right, these are neo magnet and $95 each. This box straight pounds, built with birch not mdf. Can ship for actual price, will be at the Brothers car show in Anaheim June 28th. Will be picking up new box from CSCStang at that time so may leave with him. Hard to get those C10's to pound, easy with this setup and very punchy with the 6.5s. Might fit small cut out 8's. Asking $150 or $375 with woofers
