Toby Ratcliffe Posted April 22, 2012 Report Share Posted April 22, 2012 Have you tried facing it to the rear? A majority of the time, if you can't seal the trunk off, facing the rear is normally louder for trunk installs. Quote Link to comment Share on other sites More sharing options...
max785 Posted April 22, 2012 Author Report Share Posted April 22, 2012 yeah , maybe it way louder but lost in quality and much more trunk rattle :S Quote 2001 civic dx 2 X sa12's " 1 X aq1200d Knukonceptz 4 gauge , rca Link to comment Share on other sites More sharing options...
stroupe79 Posted April 22, 2012 Report Share Posted April 22, 2012 sealing it off is the best option..it keeps the sound going into the cabin...and will lessen the rattle from your trunk...the bit of blockage from the framing wont really cause much of a problem..nothing to worry about anyways...keep your amp in the trunk..and use cardboard to make templates for the sections you need to seal off...its the easiest method...sometimes it will sound a bit different but thats usually when you go from backfiring toward taillights to turining it around to face forward (which your setup already is) so you probably wont notice it sounding different except hopefully louder simply because the space the sound will affect will be smaller due to subtracting the trunk space sound would be getting to... i would seal off any and every trunk build I have...I did it to my build in my 94 Cavalier..and had no rattle from the ass end...I did 148.4 on the dash in dbDrag in 98 with that setup...i will never run a trunk build thats not sealed forward Quote http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
max785 Posted April 22, 2012 Author Report Share Posted April 22, 2012 can I use anything to block the remaining unseal hole ? or only use mdf and foam ? Quote 2001 civic dx 2 X sa12's " 1 X aq1200d Knukonceptz 4 gauge , rca Link to comment Share on other sites More sharing options...
Ballen194 Posted April 23, 2012 Report Share Posted April 23, 2012 Yes I'd seal it off. You might want to think about just building a new box with a center port or figure out a way to get nothing in the way of that port.
