Joe X Posted February 17, 2012 Report Share Posted February 17, 2012 height 1 16, height 2 9.5, width 36, depth 1 8 depth 2 17 4 3inch ports 14inches 3 p3 10s audiopipe 1500.1d Ok so your net effective volume is 3.2 cubic feet Your tuning frequency is around 38Hz PA/Vb = 8.8 RF spec is 1.4cuft@40Hz PA/Vb about 11 So you are short on net volume and port area but not sure that can explain your problem. Do you have any electrical system upgrades? Quote Link to comment Share on other sites More sharing options...

Joe X Posted February 18, 2012 Report Share Posted February 18, 2012 (edited) Basically you need to go through a gain settings procedure to make sure you are not soft clipping. 1) you need to defeat all tone controls on the head unit and the amplifier, bass boost, and best disconnect the bass knob that the amp comes with 2) need to set the subsonic filter on the amp to nearly 30Hz. 3) go through a simple gains setting procedure, are you familiar with that?

steve volz Posted February 18, 2012 Author Report Share Posted February 18, 2012 i have the bass all the way down and the treble all the way up on the deck. I know u can use a dmm to set the gain by using the squareroot of the rms/ohms but i dont know the rms at 2.67ohms the amp is 1500 at 1ohm 950 at 2ohms 600 at 4ohms but i dont know about the rest of the settings and my ssf goes from off to 50hz would off be 0hz?

412 CVX Posted February 18, 2012 Report Share Posted February 18, 2012 Well there's your problem lol.' not enough port. maybe if they were flared you wouldn't have the scuffing. but it looks like a new box may be in order Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
