Getting those last DBs

[KennyMcCormick]

Hi everyone I'm new here and have a few quick question. My system is currently sitting at 128.1 DBs I would really like to get that up to 130. Is there anything simple that can be done to achieve this? Amp gain and bass is set just to the breaking point so I can turn the volume to 30 without any distortion HU goes to 32. Also I'm sure a ported box would help but speaker min ported is 3 cu ft I have my boxes at the max I can go at 2.6 cu ft. Would porting help or actually make it sound worse with this small of a space. It's in the trunk of a 2007 Mazda 6i

You have very low expectations. What does this setup consist of? 1 6.5 sub or a 8? 200 watts or less?

Sorry about that. I have 2 15" Kicker CompVR DVC 4ohms ran down to 2 ohms on a Pioneer 2000W amp. Each 15 is in its own 2.6 cu ft box. Which leaves about 3 inches of space, just enough to pull them to get to spare if needed.

What model amp? Pioneer does not have a real 2k. And if you can't port than you need to go to 12s.

You'll never see 2400 out of that amp. They do run 1200@1 ohm though. Ran one for a while.

had a buddy that just recently upgraded from his previous setup which was 2-12" Pioneer champion subs in a prefab slot ported box and a Pioneer 1200d Champion amp and he was around 136-137 on meter. Id also recommend getting smaller subs and port them

Yeah I'm running it at 1 ohm. Might try to make a box that moves with the trunk to get more air space and port them. I drop rear seat when turned up both will drop.

Yea your at 1 or 4 ohms not 2...how are your subs wired? And as stated above that amp does 1200@1 but if you decide to go ported (which is what you need to do to get louder) you cant use that amp as it has no subsonic filter.

Yeah mean't to put 1 instead of 2 it is ran positive from amp to positive on both speakers negative on amp to negative on both speakers. Thanks for the warning on the amp.
