08-19-2013, 01:46 PM
Hey guys i recently changed my setup and took out my DD9518. I'm currently running two Rockford P3 15s D4 wired at 1ohm.. Box is tuned to about 38Hz with a 5 1/2" wide port firing drivers side...

Hit a 146.2 outlaw and 145.4 sealed...

Soon to have 2 DD 3515 D2s on an M4 amp :)

Not bad for 600 RMS subs......

Like the fit of the box.... did make a trim panel or is your car like square in the trunck pass through? Didnt think of a side firing port in the trunck... would think it would drop DBs? Are your 6x9 holes sealed?

I had a set of the 2004esc P3's... dam good woofers. not spl kings but good sounding and had some output. Upgraded to T1's and was pleased as well....

Why the 38HZ tuning.... I know fosgate recommends tuning that high (caters to the highscool parking lot) but its gonna have a nasty hump in the response...

I would add some 45's inside the box along the froint and side walls for bracing.... might give you better and/or cleaner output.

Keep the pics coming... Im partial to cobalts.

no trim panel yet it fits pretty tight in there lol. Definitely need some more deadening on the port side its violent. Yes my 6x9 holes are sealed with second skin. Im tuned at 38 for some DD 3515s im going to put in soon :). I might build a new box for the DD 3515s.

This slams though man!!!
