[QUOTE="Jeffdachef, post: 8721111, member: 650438"] no. You get massive cancellation. Distorted waves, weird peaks or a lot of the times, negative bass. You always keep everything in the same spec'd box or else its no different than running multiple different sub brands or sub sizes in the same car... thats a recipe for disaster. Ported boxes can be tuned to be tight and musical while sealed boxes in the wrong car acoustics can sound like absolute one note wonder garbage. Its all on how you design the enclosure and how you make it fit with the vehicle's acoustics. PS the one enclosure that has BETTER than sealed box tightness, FLAT bandwidth response and loud throughout the whole bass spectrum and can get almost as loud or sometimes louder than a ported box is a 1/4 wave transmission line enclosure. A box for a single 10 would be as big as a box for a ported 15 so space is the compromise along with Complexity of design, you need someone who really knows what they are doing with the right tools to measure specific sub TS parameters because it wont be the same as what the factory states on their list because every woofer has minute discrepancies on their parameters.
