teamace24 Posted February 16, 2012 Report Share Posted February 16, 2012 Was messing with my buddys setup where i built him a ported box for his 2 12 jl audio w7 on 2400rms port and sub facing the rear to the hatch. This setup sounds very tight and loud and clear. For kicks picked up and stood his box up with both subs and port facing the roof (which even stock is extremely solid just get a thump when i bang on it), and MAN very nice difference in bass clarity, already was clear and got clearer, and overall loudness. The lows hit harder and way cleaner. Question is why was there a big difference by me pointing the subs up, was it the roof? is there something wrong with the subs pointing to the hatch? why do the bass waves sound different going to the hatch than to the roof? I really want to figure this out since my yukon 07 sounds horrible compared to his (i have 2 kicker cvx 15's port and subs to rear hatch built within spec) gains set right and clean but i get a tinny not tight bass and my roof and fenders rattle nasty and im now thinking maybe its because the subs are not pointing at anything solid? Any help?

getlocivic Posted February 17, 2012 Report Share Posted February 17, 2012 (edited) general idea for suvs and hatchbacks is subs up port back.. or subs and port up .. just helps with loading issues n such never ever done subs and port back in a suv.. subs up port back or subs and port up edit and with the rattle.. thats obviously a common issue.. any subs will make metal move.. do some spray foam and deadener.. i couldnt even imagine what a suv sounds like with no deadenr.. rattle city Edited February 17, 2012 by getlocivic Quote Link to comment Share on other sites More sharing options...
teamace24 Posted February 18, 2012 Author Report Share Posted February 18, 2012 Messed with my box today and picked it up and pointed both subs and port up to the roof. It got slightly less loud but it did clear some rattles from the outside, maybe due to it being slightly less louder maybe. Dont know if i should first deaden the back then try my box facing back again or just rebuild a box pointing subs up port back. Usually my reason for doing subs and port back is because boxes have more resale value in my experience if i get bored. Definately thinking about redoing my setup and go subs up port back now or deaden or both.

ant the ninja Posted February 18, 2012 Report Share Posted February 18, 2012 Its weird, my 15's are extremely loud facing the rear. Firing up they sound muffled and not nearly as loud, could be because my box is sealed. Quote 2002 Ford Explorer XLT Front Stage: Crescendo CCX 6.5's Rear Stage: ???
