whotry Posted December 20, 2012 Report Posted December 20, 2012 I recently bought 2 kicker L7s came on here and asked for help to design a box, a good person helped me on here i built the box but it doesn't have the power I need so I said what the heck might as well buy a 15 L7. The car it's going inside is a Lexus GS300 My trunk is a bit weird but I'm sure I can build a box to fit. If there's anyone that can help me do some calculations I'm at work and I don't have access to a computer atm. My trunk has a small rectangle in the far back then comes out bigger. The Max dem. for the small rectangle is. H-16.25 W-30.25 D- 12.25 After the small rectangle the Max dem. I can go is H-19.5 W-52.5 D-14. That's all inner dem. I've already subtracted .75 from all the measurements. Now I'm a little confused on my options for my ports if anyone can help me out I would like my box tuned anywhere from 28-32 hertz. I will be putting the two 12s on the outside and the 15 in the middle. If anyone can help me out on a sketch I would greatly appreciate it and I will be happy to post pictures while I'm constructing the box. -whotry

ThreehundredC Posted December 20, 2012 Report Posted December 20, 2012 I have my L715. in a 4.5 cubefoot box it takes upalot more room than the 12 i had..i thought my 300had a big trunk too takes most of it up
teamace24 Posted December 20, 2012 Report Posted December 20, 2012 Build a proper box for the two 12's and they will hit hard with a real amp that does atleast 1500rms.

whotry Posted December 20, 2012 Author Report Posted December 20, 2012 Yea the two 12s now take a lot of my trunk space but I plan on making a amp rack so I need some space
teamace24 Posted December 20, 2012 Report Posted December 20, 2012 Drop the 15 make a real box and get real power. Kicker l7's get really loud so something is off here. Whats your current box design specs? and what power are you running(model?) 1st Setup(SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 Audioque SDC2.5 15 subs8.7 cubes at 37hz build DONEAudioque 1200d (Audioque 1200d Sold, similar performance to my ap1500)Diamond Audio Hex 6.5 Mids n TweetsCerwin Vega Exl 400 4 channel Bridged(also have MTX 4004 not being used)1 Run of power Knu Fleks 4 Gauge2 Cheap stock Battery setup2nd Setup (SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 15 Kicker cvx (maybe two SA 15 in future)7 cubes net tuned at 34hzAlphasonik Old school 1600rms (ap 1500d sold GREAT Budget amp)JBL 6.5 Power Series Components, Infinity Kappa 6.5 3 ways, and 2 Kicker KS Tweets (LOUD)Cerwin vega exl4001 run knu Fleks OFC 0 gaugeBig 3 done1 Odyssey 1500, 1 optima yellow top d31
whotry Posted December 20, 2012 Author Report Posted December 20, 2012 For the two 12s I'm running a 1100D Memphis
whotry Posted December 20, 2012 Author Report Posted December 20, 2012 I had to chop off 5 inches off the width ofmy current box due to Wrong measurements maybe that may be the problem? I re measured everything and the specs are posted above
teamace24 Posted December 20, 2012 Report Posted December 20, 2012 As long as you are wired to 1 ohm then you are good with that amp. Box is the next suspect, whats the design? If the design and box is good as well then you are going to have to think about selling subs upgrading cone area/power. 1st Setup(SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 Audioque SDC2.5 15 subs8.7 cubes at 37hz build DONEAudioque 1200d (Audioque 1200d Sold, similar performance to my ap1500)Diamond Audio Hex 6.5 Mids n TweetsCerwin Vega Exl 400 4 channel Bridged(also have MTX 4004 not being used)1 Run of power Knu Fleks 4 Gauge2 Cheap stock Battery setup2nd Setup (SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 15 Kicker cvx (maybe two SA 15 in future)7 cubes net tuned at 34hzAlphasonik Old school 1600rms (ap 1500d sold GREAT Budget amp)JBL 6.5 Power Series Components, Infinity Kappa 6.5 3 ways, and 2 Kicker KS Tweets (LOUD)Cerwin vega exl4001 run knu Fleks OFC 0 gaugeBig 3 done1 Odyssey 1500, 1 optima yellow top d31
