MTMustang7 Posted August 29, 2011 Report Share Posted August 29, 2011 i think your score could improve with more vent area.. you have roughly 12 per cuft now. I would try 15sqin per cuft That's the problem, I don't really have any more room to increase port area. I think I'm pretty limited with having a small trunk, it's very tight with everything in there. I appreciate the suggestions and I'm open to others if you think it might help.

MTMustang7 Posted August 29, 2011 Report Share Posted August 29, 2011 The one thing I don't want to do right now is change the box. I just got this stuff in a couple months ago and the box is screwed in. I might have to try that a little later down the road. I had a feeling I was gonna have to do stuff like this that I don't want to do at the moment. Once again, thanks for the suggestions.

AA98hoe Posted August 30, 2011 Report Share Posted August 30, 2011 Clarify this for me Ray. If I'm strapped at .7 my amps see .35. So when I clamped it my rise was to 2ohms so is that split in half? Is each amp at 1 ohm. And is starting ohm is .35 or .7 TEAM DC AUDIO VEHICLE:98 chevy tahoe 2wd 3-4 drop HEADUNIT:alpine 9886 PREAMP:arcaudio FRONT STAGE:4-6 1/2s selinium,DD component set and 4-selinium tweeters in each door KICKPANELS:jl audio 5 1/4 REAR DOORS: dd components 6 1/2s HIGHS AMPS:zapco 750.2 on front doors,zapco an another 750.2 on kicks and rear doors SUBS:4-ascendant audio 18s with 5 spiders in a custom box built by KINGSUV SUB AMP: 2-dc7.5s ALTERNATORS: 3-mechmans 1- 425comp, 1-smd spec350, 1-270 with adj voltage harness on custom dc bracket WIRE:10-runs 0g front to back BATTERIES:6-d1400s TL results:157.1 at 38hz and 156.8 at headrest score @37hz.

Audio-Concepts Posted August 30, 2011 Report Share Posted August 30, 2011 Would running a sub inverted effect the box tuning on a 4th order? You designed be a ported enclosure, but I was thinking about a 4th order and running the sub inverted to not disturb the sealed chamber, plus youd be able to see the chrome motor throught the port opening, kinda give it a style!

Ray Posted August 30, 2011 Author Report Share Posted August 30, 2011 It does yes. But so little that it doesnt matter at all.

Audio-Concepts Posted August 30, 2011 Report Share Posted August 30, 2011 Ok cool, cause the sealed enclosures for.these subs is a max of 1.25cu ft. so I would use the same size enclosure you designed, but with the loading wall! To be right around a 2:1 ratio!
