tacomaguy1 Posted December 5, 2013 Report Share Posted December 5, 2013 Yeah....I've always done meter on the same side as port, opposite door open My wall now is center port. All I've tested is on passenger side w/driver door open. Hear it can be louder with meter on driver side. Gonna try that at the next comp Burping @ 36hz Team Flex Issues Link to comment Share on other sites More sharing options...
Real96SS Posted December 5, 2013 Report Share Posted December 5, 2013 My truck has driver side port but my score in the driver seat pass door open is like 2db lower than pass seat driver door open at 39hz.

miniSPLlancer Posted December 5, 2013 Report Share Posted December 5, 2013 Well I guess good thing I'm not going to be competing officially. However I will have burp and music numbers after TD. burp numbers off my usaci CD. And I got a few songs I wanna see what I hit. My teammate has a 20xx honda accord 2 door with 2 XFL 12's on a Soundqubed 2200, subs rear firing burping at 47hz he did a 144.7 at the headrest. He has a H/O alt, only front battery hooked up at the time and one run +/- Just to give you an idea 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals Link to comment Share on other sites More sharing options...
cjvue Posted December 5, 2013 Report Share Posted December 5, 2013 I compete in Meca and have for a couple years now. with all things being the same, 39-47hz is the sweet spot for Meca, seems to be what the meter likes at that position. I burp at 53hz in Meca and do a 150.4 (unofficially) and a 149.4 last season was my highest score. In IASCA, sealed on the dash I was .4-1 db louder, due to higher tuning. I consider under 30hz burping to be tuned low for Meca. Most of the competitors that have walls put the port on the driver side and meter at the driver headrest with passenger door open. You burp frequency is pretty high for meca. My buddy David burp around that frequency as well in his SUV for meca single zv3 on aq3500.1 did a 151db My Build Log- T E A M S U N D O W N A U D I O - 2013 DbDrag WF SS1-2 - 5th Place 154.6db 2013 MECA Mod3 CA State Final Champ 153.4db Powered by: Sundown Audio Link to comment Share on other sites More sharing options...
ALPINE408 Posted December 5, 2013 Report Share Posted December 5, 2013 I might know a thing or two about this subject........... Mario your peak does not change from headrest to dash 99% of the time but your score does change Have you ever had your woofers blown? Link to comment Share on other sites More sharing options...

He has a H/O alt, only front battery hooked up at the time and one run +/- Just to give you an idea Lol i actually did a 44.8 outlaw. 47hz Skar 2500. Shit box. Sealed off forward. Front and rear AGM battery. Battery decently dead from demoing all day. CCA wire, grounded to strut towers. But since then I've doubled power. Got a way better box. Got way better electrical. And it sounds wayyyyyyy the hell louder. I am hoping for a 48+. I'll keep everyone informed. I'm still getting used to this metering thing. Its a skill for sure. I'm just a noob who did what the judge was telling me to do. I even pre maturly ran my run because I forgot to honk my horn (I was excited) But since I'm not competing I'll be able to do a whole bunch of testing, and not limited to 2 runs. That was intimidating with a whole crowd of people around me. Maybe in spring when I replace my batteries and alternator I'll try competing again and not be soooo noobish this time. It's harder then It looks IMO.

miniSPLlancer Posted December 5, 2013 Report Share Posted December 5, 2013 I don't have a choice if I want max spl, my vehicle peaks at 53hz. But I still do pnp though. I enjoy meca and I really like street class. I compete in S4. And I'm all about the fusing. Sort of levels out the playing field. 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals Link to comment Share on other sites More sharing options...

My vehicle peaks at 53 FOR Meca. I've never tested resonant frequency for any other organization. In Meca my car peaks at 53 which is where I see my highest SPL number. For 3 years I've tried lots of designs and boxes and spent a lot of money on wood and did everything I could to gain that 1db. I was so desperate I tried what other people have said knowing that there was a real GOOD chance that design would suck ass, and it usually did LOL. I've got a lot of time in my vehicle for Meca for the little number I'm doing. Maybe one day I'll figure out what needs to be done and finally hit the number I want. 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals Link to comment Share on other sites More sharing options...
