SnowDrifter Posted July 8, 2013 Report Share Posted July 8, 2013 Going to be getting a 9k in a couple weeks to power my 12s. I've never ran anywhere near that much power before so hopefully someone can help me out with a starting point with a box? No reason to waste time testing things that we know won't work lol. Especially since it's tough to build test boxes at this power/pressure level. They all have to be solid and reinforced. No such thing as a throwaway box I have a pair of crossfire XS-SPL 12s. Will be wired at .5 on 14v electrical. Box will be subs back/port back with a 9" aero. Tuning TBD. Probably somewhere in the 40hz range, pending testing. Was thinking around 3cuft for the pair? I'm not really sure where to begin with this since I've never ran this much power before, nor have I ever had a box tuned this high before lol. I'm fine not having low notes. Lots of folks where I am have a <30hz addiction lol. I'm trying to be different ~~~~~~~~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...

__d_a_v_i_d__ Posted July 8, 2013 Report Share Posted July 8, 2013 3 cubes for 12s ? ? And why sooo high tuning !!? I would start at 4.5 cubes with that power. I have 5 cubes for my 12s and was going to run 9k to it, but only had a chance to do 7k. And they wanted more ...

Burp box.Edit: to clarify I'll be using one of those adjustable metal ports from psycho acoustics. Plan is to have a box that will do well on the meter but can also work for daily. ~~~~~~~~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...

SnowDrifter Posted July 8, 2013 Author Report Share Posted July 8, 2013 Oh alright . Should see 150+ easy with a burp . That's the plan lol. Was doing a 147.2 in a ghettorig box on 3.5k and lower voltage. And the box peaked a solid 10hz below vehicle peak too. Ima rage quit if this doesn't do a 150 lol ~~~~~~~~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...
