spl 147.8

I just had my car metered at a local show and shine and was wondering if 147.8 was a good place to be wiht a mrd-m1000, 2 treo ssi 12's, and a large centerport enclosure.Alpine cda-9855

If you intend to compete in SPL find out what db the winner had in the last local contest in your category.  Then go from there.  147.8 db is plenty loud for me, I can assure you that!Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

nice score impressive for 2 12" subs did you make the enclosure yourself  and was the meter on the dash?? 1974 ford pinto 4 15" punch Z power punch bd 1001 pioneer DEH-6700

what meter?   Term Lab or Audio Control?,   If term lab very nice score, if audio control still a good score, but keep working before you go into a show2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

The mic makes a big differance, the audiocontol mic is not as accurate as the term lab. Also was the mic on the dash/windsheild or at the port or headrest?? Where I live 147 would be a really good score, most people hit high 130s or low 140s and not much higher. One guy with a caravan with 4 15" subs in a wall gettin like 3000Wa piece hit 155db.

I think  last time I had my car metered i hit a143.7 with two JL W3 10's...i was pretty proud...160.7 in the port...but good goin' man!Don't hop it...Bodydrop it

yeah, meter makes a huge differance. If its official DbDrag compitition, you should have been metered at the dash with the termlab and that is a damn good score. Very loud... But that sounds about right... ported treo's... what vehicle? What is the box tuned to? What did you play to hit that number?04 dodge neon SXT

it's a 98 cavalier and I played a 50hz tone. I am not sure what the box is tuned to. The passenger was just holding the mike in front of her chest.Alpine cda-9855

wasnt a term pro then... Those suction cup to the windsheild... You can probably increase that number if you find the right note to play, as high as 2-3 dB more!04 dodge neon SXT
