Miakehl Posted February 17, 2010 Report Share Posted February 17, 2010 I'm going to wing this one and say... ones on the inside and one on the outside.... Other than that, no I don't think so. Some of the loudest cars I've seen ran external aeroports. [HOONIGAN]* '01 Ford F-250 LWBJVC KD-R950BT / Alpine MRV-M500 / (2) SWA-10s4 Link to comment Share on other sites More sharing options...
