ilovebass808 Posted January 10, 2012 Author Report Share Posted January 10, 2012 That means I just gotta keep testing and see what works?

FroznBeavrBALLs Posted January 10, 2012 Report Share Posted January 10, 2012 i've never competed. but i do know you have to test different boxes tuned to different frequencies to find what your car peaks at. test it on a TL that is.

stroupe79 Posted January 10, 2012 Report Share Posted January 10, 2012 I heard my 05 grand Cherokee's res.freq. is 47hz...so does this mean that's were it would be highest spl regardless if box is tuned to 32hz? Or if box was tuned to 47 it would score higher at 47 than any other setup?..Just wondering Quote http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...

n8ball2013 Posted January 10, 2012 Report Share Posted January 10, 2012 depending on other factors you wont peak at 47 either. you may peak higher or lower depending on your enclosure and internal space taken up by amps and such.

stroupe79 Posted January 10, 2012 Report Share Posted January 10, 2012 Thanks...I will just tune to what I like and not for the meter anyways...just curious really Quote http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
ALPINE408 Posted January 10, 2012 Report Share Posted January 10, 2012 SPL boxes peak output are frequently in the 40s region, enclosures are usually tighter the subwoofers used are usually high Fs. Just to give you an idea. actually they are meant to peak at the resonant frequency of the vehicle. That way your enclosure peak and cabin peak are working together. it doesnt necessarily mean its in the 40s. CRXs peak in the 50s. tahoes and hte like peak in the 30s. Woofers dont need to have a higher FS to be used in spl applications. They just need to handle an absurd amount of power for a few seconds. Thats why you usually see the big 4inch coiled woofers. That does lend itself to have a higher fs in most cases but not always. all spl records have been done with a 3 inch coil i dunno about this year tho Quote Have you ever had your woofers blown?

varietyguy Posted January 10, 2012 Report Share Posted January 10, 2012 If you are building a full out spl vehicle your work will never be done because you are constantly trying to get louder. Your sub has a peak frequency as well as your enclosure and vehicle. These are variables and therefore can change when you change another. Example: I don't remember the guys name but he did a full build of his 2 door jeep cherokee. He was louder with no deadening because the spl caused his roof to flex and produce more spl. All I could look at is the amount of deadener he wasted and threw away to figure this out. If you build an spl specific box your not going to be able to listen to music because it will sound like crap. You are also not running a lot of power to overwhelm your subs so you don't want a small box with big port. I personally would suggest an enclosure tuned to the mid to high 30's this way you can still listen to music but your going to peak at a higher frequency. (assuming your current box is a prefab or close to it) Quote 1992 Mazda 323 http://www.stevemead...323-wall-build/ Link to comment Share on other sites More sharing options...
ilovebass808 Posted January 11, 2012 Author Report Share Posted January 11, 2012 After all the opinions that I read. I think I'm just going to keep my box that I currently have now. I appreciate everyone who shared their opinion! Thanks!
