loganuf Posted August 28, 2008 Report Share Posted August 28, 2008 Alrite well i just got my system all hooked up today, and it sounds really good, but there seems to be a problem with my amp. I think i know the problem, and im sure i'll get the response that i think i will , but here it is: Im running a kicker zx2500.1 on 4 12" L7s that are all dual 4 ohms, so i have it wired to 2 ohms. I am running 0 gauge wire with a stock alt, stock battery and a kinetik 800. I know that thats not enough battery for my amp, but its all i could get for now. I had the gain set at about 1/4 of the way up, maybe a little more, and it was bumping good for a while, but when it hits a really hard note at full tilt, the amp cuts out for a second and goes into protect for ony a second, and then i starts bumpin again.....when i turned the gain down it seemed to be fine. So is it because im getting such drastic voltage drop? i had a voltage meter that i was using and it was reading above 12 volts the whole time, but im not sure how accurate that is.....so is there something that i can do on the settings of the amp, like the crossover, in order to fix this problem?

dmanson Posted August 28, 2008 Report Share Posted August 28, 2008 sounds like you need to up the electrical potna. you can cut the gains down more but get that electrical up to par.

loganuf Posted August 28, 2008 Author Report Share Posted August 28, 2008 (edited) sounds like you need to up the electrical potna. you can cut the gains down more but get that electrical up to par. yea thats what i thought.....well with the gain at exactly 1/4 of the way up, it doesnt go into protect, and it still slams.....so until i get another batt and a better alt, it'll have to stay there Edited August 28, 2008 by loganuf Quote 2000 Eddie Bauer Expedition: Alpine CDA 9883 2x 18" DC lvl 4 D2 10.7 cu ft box 33hz knu 1/0 wire amp: Kicker ZX2500.1 Kinetik Link to comment Share on other sites More sharing options...
Guest Posted August 28, 2008 Report Share Posted August 28, 2008 check your ground, make sure the paint is ground/scraped off where the lug touches the metal. Quote Link to comment Share on other sites More sharing options...
loganuf Posted August 28, 2008 Author Report Share Posted August 28, 2008 check your ground, make sure the paint is ground/scraped off where the lug touches the metal. really that can affect it? ill def. check it tomorrow Quote 2000 Eddie Bauer Expedition: Alpine CDA 9883 2x 18" DC lvl 4 D2 10.7 cu ft box 33hz knu 1/0 wire amp: Kicker ZX2500.1 Kinetik Link to comment Share on other sites More sharing options...

Guest Posted August 28, 2008 Report Share Posted August 28, 2008 a bad ground can cause a whole mess of problems. check all the wiring, make sure its secured and has a clean connection. (metal to metal, not metal to rust to metal) Quote Link to comment Share on other sites More sharing options...
rusty959 Posted August 28, 2008 Report Share Posted August 28, 2008 Have a dmm? check the voltage at the amp when the bass hits, especially what it gets to when the amp cuts out. I am having the same problem with my kx1200.1, but it isn't due to voltage.

S1R-BLUNTZWORTH Posted August 28, 2008 Report Share Posted August 28, 2008 probably replacing the alternator with a higher output will fix the clipping... i was having amp clipping and lights dimming, car stalling etc. with my t1500-1bd amp I had just put in, and ended up having to upgrade to a more powerful alt. I didn't need to get a super powerful one, but a 120 amp(original was only 70amps) alternator just barely cut the mustard for my setup. No more amp clipping or car stalling in the middle of the road, yay! alternator was only $140 at checker auto parts, best damn $ investment for insufficient power. that is, if you replace it yourself Quote Amps - 2x t1500-1bd Subs - 2x hdc315's(copper d2's) Deck - 1940's Amplitude Modulation radio Link to comment Share on other sites More sharing options...
jlgn_2000 Posted August 28, 2008 Report Share Posted August 28, 2008 deffinately the voltage drop, I have the same amp, well the kx2500.1, when my car was all stock it would always go into protect when the big bass notes hit, I just got an ho alt and a 2nd battery and now its good, as for your voltmeter...I guarantee that if you check the voltage at the amp it will show you a much lower reading than what the one up on the dash is telling you Quote 94 3000gt 18" Kicker Solo X KX2500.1 2 KX350.4 8 JBL Coax Speakers 250A Mechman Alt Link to comment Share on other sites More sharing options...
