g6ryder Posted October 1, 2011 Report Share Posted October 1, 2011 (edited) So i have a pair of Skar vvx 12s laying around so i figured ill throw a single 12 in this box i have laying around i do not know much about it i picked up off craigslist along time ago for a cheap price seller told me he hit a 147 with a re xxx 12" idk how much truth there is to that if any it looks to me more of a burp box than anything 16" all around with a 16" 6" aero port idk how this will do spl wise but we will see i just bought a spl lab so thats what the numbers will be coming from in a trunk of a pontiac g6 so dont expect great numbers bc my car doesnt get numbers well at all!!! But i figured it will be a fun thing to mess with try different things to see what works best shorting for 140+db but not going to hold my breath my car just doesnt meter well going off my past numbers it will be ran off my current amp which is a Planet Audio bb2400 @ 2 ohms so not much power either Got about 30 min of testing today here are some pics all testing down in kick on a Planet Audio bb2400 rated at 1600rms @ 2ohm lucky if i ever seen 1k this sub was brand new never seen power till today no break in period at all! All testing was done on a 50htz tone burp my car meters horribly back seats were folded down the during all testing so all in i started at 136.23db and finished with a 138.62 in about 25min i gained 2.39db just by doing odds and ends things moving seats,leaning seats forward,removing back seat, moving box around. This is what i stated with the sub back port on drivers side mic in passenger kick! Gain of .43db Gain of .08db Gain of .3db Here i moved sub facing towards the inside of the cabin port passenger, mic in drivers kick Gain of .84db Gain of .74db Here i removed my backseat (takes about 5sec) Edited October 1, 2011 by g6ryder Quote www.wooferwarehouse.com Link to comment Share on other sites More sharing options...

fecupe2001 Posted October 3, 2011 Report Share Posted October 3, 2011 Not bad hommie, nice work, this topic reminds me my SPL gains topic, take a look at it at the SPL room to see what other things you can try out, that´s a very nice score indeed, try changing the amplifier since i know that score could be way louder if you weren´t having a big ass final load after impedance rise because the amp it´s wired at 2 ohms...
