[QUOTE="slowfive0, post: 1274271, member: 564634"] Hey guys, Great site! I'm a newbie attempting my first box build. Vehicle is a 2000 Chevy Ext. cab pickup. I'm building the box to go under the rear seat to house 2 12's. Here is my problem and question. I don't know what the subwoofer requirements are? They are 12", Have MD2 on the cone. The sticker on the back of the magnet says: Impact High Performance Drivers There is a big M for a symbol? 74792 / MD2128 These are 10 years old if not a little more. The box I measured up (haven't made it yet) will have approximately 1.25 cu/ft per speaker. I was leaning towards sealed just because of my inexperience and not knowing what the speakers were designed for. What would you guys recommend for a volume and have you ever heard of these speakers? (I'm not against ported if I can make it work without knowing the speaker requirements.) Also, should I divide the box up in the middle (separate chamber for each speaker)???? Thank you for any input! [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] P.S. I will be powering it up with a Rockford Fosgate amp (200) bridged---roughly same age as speakers. [/QUOTE]
