memphisbasshead Posted July 23, 2010 Report Share Posted July 23, 2010 Okay I was wondering weather if I should get 2 DC Audio Level 3 15's sealed in a 3.4 cubic ft box or 2 DC Audio Level 3 12's ported in a 3.4 cubic ft box tuned to 35 hz after displacement.I want to be able to hit at least a 142 sealed on the dash. I will be putting 1200 watts rms to either setup.

TeejayBee Posted July 23, 2010 Report Share Posted July 23, 2010 Id say do two 12"s give you some more wiggle room to move the box around and the subs wont get in the way if you get what i mean and if your putting 1.2k to two 12"s they might hit harder then the 15"s since the cone is smaller Quote Link to comment Share on other sites More sharing options...

Robert8252 Posted July 23, 2010 Report Share Posted July 23, 2010 Grrrr. There's no way for Anyone to know how loud it will be. In a suv that's possible, in a truck it's possible, but in a car you would likely still be in the 30's DB range. And ported over sealed Quote 2013 F150 Crew Cab Old Build Log Feedback 2013 F150 Equipment - Some Awesome Stereo Sound Making Stuff Link to comment Share on other sites More sharing options...
LT.Smoke Posted July 23, 2010 Report Share Posted July 23, 2010 Yes i would definitely go with the 12's. You shouldnt have a problem getting into the 140's . I was able to get into the 50's with a single 12 in my old 96 accord bro its all about the box and playing with it in the trunk to find out where its the loudest and sounds the best Quote Team MaxRetribution Si Vis Pacem Parabellum Id rather be judged by 12 than carried by 6 Bowhunting- Life Begins and Ends at Full Draw Bowhunting Team Fatal Trajectory Hunt Team http://www.stevemeadedesigns.com/board/topic/49335-sick96vtecaccords-t-line-build/?hl=sick96vtecaccord << Accord Build http://www.stevemeadedesigns.com/board/topic/68498-smokedout08impalas-tline-build/?hl=+sick96vtecaccord << Impala T-line build Rebassed.com for all your music needs 👌 Link to comment Share on other sites More sharing options...

Im in the 130's right now with a single 8 on 100 watts in my 08 impala. cool so i guess i'm going with the 12's. and should i tune to 36 hz with about 12 sq inches of port area per cubic ft and the box is 3 cubes after displacement. i kinda wanted to tune high for spl and since most of the music i listen to is rock i figured that would be a good tuning frequency.

LT.Smoke Posted July 23, 2010 Report Share Posted July 23, 2010 Try to stay under 40 Hz. I would tune to like 34 if it was me but thats just me. But wish you good luck with your build and keep up informed on how its coming along. BTW great choice on woofers Quote Team MaxRetribution Si Vis Pacem Parabellum Id rather be judged by 12 than carried by 6 Bowhunting- Life Begins and Ends at Full Draw Bowhunting Team Fatal Trajectory Hunt Team http://www.stevemeadedesigns.com/board/topic/49335-sick96vtecaccords-t-line-build/?hl=sick96vtecaccord << Accord Build http://www.stevemeadedesigns.com/board/topic/68498-smokedout08impalas-tline-build/?hl=+sick96vtecaccord << Impala T-line build Rebassed.com for all your music needs 👌 Link to comment Share on other sites More sharing options...
