My first meter readings

[Mtndew 10+ year member]

Yesterday i went to a local audio shop and had my DD3515 in a 5.5 cube box @ 32 hertz im my ext cab s10 metered. I did 137.4 legal and 147.3 outlaw in the port with a 38hz peak.. this is my first time being metered and will be looking for improvements as i go. i plan on doing a blow through in the future how well was this score for my first time?? Any advise and thoughts would be lovely..

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

What amp and ohm load were you running?

 

[Mtndew 10+ year member]

well its 5.5 before displacement and port.. and i have a Planet audio PDX 2000 watt amp at 2ohms on it right now its grossly underpowered but i got the amp for a pretty good deal so i cant complain.

seems awfully low...

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

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

 

[SicAudio 5,000+ posts]

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...
