My first meter readings

Box is probably way to big if its 5.5 cubes after port and displacement.

What amp and ohm load were you running?

seems awfully low...

and if it is peaking at 38Hz I would triple check the tuning...

this, i fart louder than that

Not a bad outlaw score

I dont think it's too bad. With a truck though I would guess you should hit 140+. I did 136 with 2 12's in a prefab box in my astro. Another guy did 144 with 3 10's in an S-10. I think you're amp may be the weak link.

I doubt its the amp... it should be pushing 1kw at 1 ohm...

a single decent 12" in a decent box will hit a 137 easily on 500 rms... in the cab of a p/u truck...

2 12's on 1500 will do a 145 pretty easy in a minivan or suv...

and in the port? thats a realllllly low score for a port...

I did a 137.9 out of a trunk on a single 12 and 750rms...thats with the car off and metering on music...so that score seems pretty low

Just needs some tuning. Should have plenty of room for improvement. I did a 137 legal with 2 8's and 700 rms so you should easily be able to get into the low 40's

easily into the 40's...

I wasn't gonna post our results but since others did we are doing 139 in a trunk of a single 12 and 500 rms

147.3 on music and 150.1 in an suv on 2 12's and 1600 rms..

Care to say what equipment? Or is it secret?

Mine was a Treo TSX on an MBQ DSC 1500d

the 139 is on a zeus sub in 2.6cf tuned at 36Hz with a 50hz -3db tone in a 99 alero and a dsc480 using the dupe function and bridged

the 147 is on 2 old school brutus on an old school brutus amp at 15 volts in a 2000 windstar in 3.5cf tuned at 38Hz

both enclosures were designed by the trunk car champ M Stiers to be musical and still very loud.

me and my customer could not be more happy with the results lol

Not bad. I think I am around 139 on a tone, but with 750rms rather then 500...

you def need a better box bro should be 3dbs up easy. it all in ur enclosure.
