Phawstir Posted July 4, 2013 Report Share Posted July 4, 2013 I'm planning on designing (through Torres) and building a sub up port back config. for a single Alpine Type R 15 in my Jeep Cherokee (SUV). My first of a few questions...Should I stack the port instead of having it bend in an L-shape? example: Thanks in advance! 2000 Jeep Cherokee 15" Alpine Type R box build coming soon!

Hellbilly429 Posted July 4, 2013 Report Share Posted July 4, 2013 Good question dude, are you doing a single baffle or double? I know one benefit of a L-port is the added structural support, but not sure on the stacked port 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
Phawstir Posted July 4, 2013 Author Report Share Posted July 4, 2013 I was planning on a single baffle but with bracing dowels for support. I played around with numbers for a double baffle so it's not completely out of the question, but this will be a low power setup, only 300 watts 2000 Jeep Cherokee 15" Alpine Type R box build coming soon!

Phawstir Posted July 4, 2013 Author Report Share Posted July 4, 2013 Obviously woofer position will be important in my design too. Where am I best to place the woofer? Far from the port stack or right next to it? Would love to learn more on avoiding having the sub unload into the port 2000 Jeep Cherokee 15" Alpine Type R box build coming soon!

SnowDrifter Posted July 4, 2013 Report Share Posted July 4, 2013 Run it across the back in the L shape. Having a single 90" bend will me more efficient than several 180" bends ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Hellbilly429 Posted July 4, 2013 Report Share Posted July 4, 2013 Never tried it any other way than L port, but have had awesome luck with L ports. If you round over the angle on the L and the outside of it, and make sure the port is the same width throughout the port you will help the efficiency and airflow of the box out. 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
Phawstir Posted July 4, 2013 Author Report Share Posted July 4, 2013 Thanks everybody. Aiming for 3.5 cubes net tuned to 35 with nearly 14in2 of port per foot.Will I have any loading issues placing the sub as far away as possible from the port on the top baffle? That is the only way my dimensions will work I believe. Like this crude sketch: OR am I better off placing the sub in the middle of the box? or over/behind the port walls? 2000 Jeep Cherokee 15" Alpine Type R box build coming soon!

Joe X Posted July 4, 2013 Report Share Posted July 4, 2013 It depends on how long the port is after the turn. Link to comment Share on other sites More sharing options...
