PostSubject: box size and removing the back seat   box size and removing the back seat Icon_minitimeSun Jul 20, 2008 11:53 am

I have two Memphis m3 12s in a box with 3 cu feet per woofer in a vented box. I was wondering if I went with a 4 cu feet per woofer box would that increase my spl. I have been running around 136.7 and 138.00 all year with the back seat in. I have a 1998 town car. And I am pushing them with a Memphis 1100d. I need to know will the box change make a difference and will removing my back seat make a difference/

PostSubject: That was a mistake in my post   box size and removing the back seat Icon_minitimeSun Jul 20, 2008 3:41 pm

the minimum airspace for my subs are 3.00 and the optional airspace is 4.00 which would give me the highest spl. The 3.00 cu ft box is recommended to be tuned at 45 and the 4.00 cu ft is to be tuned at 35 please help.

yes just one 1000d I have another . Because I plan to go with four m3 12s. But I only have three subs. The four is on back order. And I have a comp next weekend I want to be in. So will a going from 1.5 to 1.75 or 2.0 get me a better score.And what about the back seat

If you take the backseat out youll be in Mod

And yes, try any one of those

2.0cu will prolly be best on music

That being said i have my Type Rs in 1.5cu net and its veryy musical on any note

Good Luck

But 3cu is DEF. too big for one 12 in my opinion

Unless you mean 3cu gross and not takin out port and sub displacement

Got a pic of the box?

And get some more power......2500d would do for now....than on to the big boy 4kw.....that would be purdy nice for some numbers
