MonkeyMan Posted October 30, 2015 Report Share Posted October 30, 2015 Although you've already found this out, to go from 142dB to 150dB, you'd realistically need somewhere around 10 times the power... Its time for a new box Link to comment Share on other sites More sharing options...

Wagonized Posted November 26, 2015 Report Share Posted November 26, 2015 If you are just trying to get it to 150 then Id do this:Build one enclosure that sounds perfect on music...just how you like it. Thats super easy.Then build a few different ones to test/tune and use as your SPL enclosure. If you can break 150 with that gear youre honestly doing something wrong.Anywho, heres what to do...1) enclosure is way too tall....make it shorter so air can pass over top 2) switch to aeroports, far easier to tune 3) go with a much smaller box. For SPL id suggest doing about 5 cubic feet. Or if you have more time on the sensor to play around then start at 6 cubic feet and keep cutting the box smaller and smaller and re-testing. 4) Deadening different areas of the cabin helps a shit-ton. Up to 5-6db. But can also hurt the score quite severely at times. 5) Play with your interior...thats a huge gain right there...seat position, glove box, center console, vents, visors, etcI will say this though....After this experience you will likely go with smaller woofers from now on if trying to build an SPL setup in an SUV. Ive been in a similar situation...Running 2 18s in a little 84 s10 blazer trying to get it loud. And only managed 151.7db. Mind you, I didnt test much and only built one box all year but there wasnt much I could change because those woofers were shoe-horned in the cargo area so tightly. You would be louder running a single 15 than you will running your single 21 because you have much more enclosure options. The trick is finding the cone area/enclosure volume sweet spot for your vehicle...usually its far smaller than youd think.Welcome to the world of SPL....it gets frustrating as hell BUILT NOT BOUGHT ********LOOKING FOR NEW GROUND POUNDER TO BUILD********1981 Malibu Wagon - Iron Block LS, Single Turbo, Nitrous, 6 Speed, Pump Gas, street car. --UNDER CONSTRUCTION Goals are to make 1000 rwhp and 9 second quarter mile 1997 Explorer 157.8.
