X2 on what penn said. Also when I build my shiz I usually go for daily tuning and see how loud it will get. I dont see much point in building a stereo with all the effort and what not to just burp it for 5 seconds. Plus car audio should be about, well, car audio. I personally use my setups to listen to music and I want to know how loud it is when Im actually using it for that intended purpose, not farting at 60hz. PS Will, Bryan and I are gonna run the massive sealed for a bit and see how it does //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
