[QUOTE="bgowdy, post: 8472679, member: 632121"] Ok, so im looking get some good ideas for enclosure for my Sp4 15. This will be a sub up port back build(suv or hatchback depending on which vehicle i get, more and likely a PT Crusier). for now will it will be run on about 2500 rms but will be upgrading power to around 4k(electrical is not a issue, so no need to ask about it). From what im ready im seeing alot of people saying 3.75 - 4 cubes net and aim for 16 Sq-inches of port per cube and tune 32-34. i want to it play lows good of course but want it to meter decent if i compete the occasional comp. For the AB Hd15 i have now, its tuned around 35 and plays lows pretty well. So i assume the sp4 would play better lows in the same box seeing its a "low end monster" as people call it. I really dont want to tune to 32hz, i was thinking to keep it along the lines of 35-36hz like i am now though its only 3-4hz difference.The SP4 should still should dig lower than what i had. The HD15 played down to 28hz surprisingly good(ALA Dj Slick-Ricks music Zips). But thanks for any info and ideas. I just dont have any hands exp with the sp4 [/QUOTE]
