Carnag3 Posted June 10, 2010 Author Report Posted June 10, 2010 I'll try swapping the wires from the amps, if the same sub is doing still doing it, I'll take it out and inspect it. By the way, their isn't a huge difference is movement, but its noticeable by eye. One thing that I find dumb is that with the gains matched at 47.9, one amp is gain half up, the other is about 3/4. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!

I had a bit of problems with my rear sub trying to unload on me... but switching and putting the slightly less powerful on the farther sub fixed the problem... edit: Nevermind I see they are equidistant...

One thing that I find dumb is that with the gains matched at 47.9, one amp is gain half up, the other is about 3/4. this one got me thinkin. id check the ohm loads coming from the box just to check it off the list and then id start looking at the amps. any weird sounds too? im learnin too so dont hate lol just an idea(what i would try first) March 2010 SOTM winner my old buildhttp://www.stevemeadedesigns.com/board/topic/50219-dank-aka-crackers-bonne-new-v2-build-in-the-works-hahahaaaaaa/page__hl__crackers my youtube page - http://www.youtube.com/profile?user=jackiedan04#g/u my feedback - http://www.stevemeadedesigns.com/board/topic/56540-official-cracker-feedback/ i need tacos and bass to live!!!!! and will NEVER change hahaaaa TEAM NOIZE VIOLATION
VaBeachKevin Posted June 10, 2010 Report Posted June 10, 2010 I would check the ohms on each sub and make sure nothing looks odd with each driver. Then flip flop the amps. If the same sub is acting odd then you know its not an amp problem and more of a sub problem. 99 Ford Explorer Sport Alpine 9886 Infinity 7541a JL 12w3 Viper 771xv
Slawsen Posted June 10, 2010 Report Posted June 10, 2010 Obviously the gains aren't matched if one amp is up 3/4 and the other 1/2... If they're the exact same amp then you have some sort of wiring problem. Could possibly be the RCAs going to the one amp..maybe they're going bad and the preamp voltage is low? 00' Nissan Xterra Always under construction :] HU: Pioneer DEH3100-UB Mids & Highs: Kicker DS Component Set & Crescendo tweeters Mids & Highs Amp: Rockford 150.2 Subwoofer: 2 DC Audio LV 4 18"s Subwoofer Amp: Hifonics Brutus 2005d you been hanging out with jeff and dustin with that green paint? its yellow so it has to be loud.
Carnag3 Posted June 10, 2010 Author Report Posted June 10, 2010 There is one rca coming from the sub out on the alpine going to the back, then they are split with a y-adapter. Daisey chaining them seems to only work when strapped. 2000 Blazer 4dr -24" Boss 330s -Lowered 2/3 -5000k Hids w Projector Retro -Candy tails -LED interior lighting -20% tint 35% windshield -Alpine 9886 HU -RF P1462 Dash -RF P1652 Front -RF P1652 Rear -Two 18" Fi BTLs -MB Quart Onyx 4.80 -Two Audioque AQ2200Ds -Xs Powerr D5100, 2 Powersafe G31s -Knukoncepts 1/0 wire -Mechman 270 Alt w Boost Module -10.4 Net @ 28hz 140sq.inch of port My Youtube Channel!!
