audioholic, i tried to clear that up with my last post stating that i was looking into the audioq's but the more i look the worse they look for what im trying to accomplish, i figured id make this post some subs would be thrown out there and we would discuss them, thats what i was going for this when writing the thread up. And every sub thats been stated ive researched and givin my thanks, i appriciate every thus far just for the record fellas. so let me clear up what im looking for. I have a 2007 tahoe and ive tried everything memphis car audio offers and even plenty of kickers in every different sub inclosure my shop and i can come up with along with more amps than i can think of, my buddy just did a system that is blowing my daily driver setup out of the water, my most recent and the system i have installed at this moment is 4 pr 15's (i know they ****) and a 1500d, i know its a small cheap setup but we were just seeing what numbers we could get out of the new pr's in a 16.4 cu box tuned to 30 or 31 maxing out at 34htz, it hit a little 146.6 on the tl in the kick pod. So not to shabby but my buddy one upped me and did a cut through in his ranger and has put 6 cm's in it and im not sure what the exact box size is but i know its tuned to 34htz and its all being ran off a mcd4000d. ITS BLOWING ME OUT OF THE WATER WITH LOW BASS. im not a big fan of building systems for numbers im more deep bass that hurts you so my next build im wanting to step up to 4 18's on at least 10k with a wall, and considering a double or triple setup of aragi's, havnt decided on my battery choice quite yet, im just running 2 red tops at this time, with the wall i should be able to pull at least 24-26cubes out of it...with all that being said were about to put 4 audioq hdc 3's 18's in a 21cu box in a bronco and the guy will be running 2 hifonics 2600's and just a stock alternator with an aragi extra alternator for now.....So the big question is how do i top all of them, ive just moved so im wanting to do this system by myself under my on new knowledge, he will be helping me build my box and wiring but i want the surprise of all the products.
