I posted this spl at a local test -n-tune,I would like your opinions on this number. I just finished my install of a 140 amp alternator ,Pioneer deh-p470mp HU,Pioneer peq -6500 eq,BBE signal processor,Hifonics ZX-8000 5 CH AMP,Polk MMC 525,MMC690,MM2104 10 in sub,the 6x9 and 10 in are mounted in the rear deck,the 5.25 are up front in pods by the kick panels.The sub ''box'' is made from a 12 in cardboard tube ,a concrete form,lightweight-ridgid cheap ,Home Depot!This is all in a 1980 Trans Am treated with 2 layers of Super Dynamat. I built this system to be accurate and powerful it sounds great! Thanx tell me what you guy`s think!:D

Sounds like fun to me!

What frequency do you get 128db's at? Any harmonic distortions at that level?

It was made using track 3 from BASS MEKANIC I also backed it up with track 3 Rush Moving Pictures ''YYZ'' the music was clear,The rest I dont know about,I didnot get a print out, I was also the only one running a single sub or a single amp. I did post the lowest score.The highest was 146 db, 4 12`s two amps Rockford/Fosgate. I think I done OK!

That`s a big picture! This car is not perfect, a work in progress if you will,There are a few cracks, dings , ect, the car is 25 yrs old!

trippy looking car, pretty sweet. i like the position of the sub, too, i'm sure that helped the score a bit. well done, in any case.

Thanks Neo,I was just wondering if that was a good solid # that was the first time I took part in a test-n-tune .
