[QUOTE="Jeffdachef, post: 8333189, member: 650438"] [B]Is your box as well built and designed as his[/B]? Is your amp as quality is his?(500 watts from a good amp is totally worlds apart from 500 watts from a cheapo amp) is your voltages as stable at 14.4V as his? Is your impedance rise at a good point or is it waay too **** high? Does your vehicle have a blow through hole to let the bass in the cabin like his? Its very different for each setup man and it takes work to get it loud. Its not just toss everything in and hope to god it flexes, sorry it almost never works that way buddy unless you have a crazy build and know what you are doing. The sedona line from PPI is just like power acoustik pretty overrated. To get your sh*t setup right FOLLOW these. That being said, set your head unit level to 75-85% volume, use a -6 db 50hz test tone, subwoofer level all the way up. High pass and low pass filters on the head unit set to 80hz. Head unit EQ set to flat, bass boost set to none, loudness off. Subsonic filter set to 75% of your ported box's tuning frequency. Low pass filter on the amp at 80hz. Doing it by multi-meter: just follow the guides Doing it by ear: have the tone playing, subs hooked up, start turning the level knob from left to right slowly. When you hear it distort or the tonality of the bass starts to change, then you are done. If it stops getting louder then you are done. In both those situations back it off a slight bit. Btw it looks like guy in the video looks like has an alpine mrp500, That amp puts out good power even with box rise and its a lot more efficient and clean compared to a ppi sedona. [/QUOTE]
