tonedeaf Posted July 17, 2011 Report Share Posted July 17, 2011 Maybe a tiny bit, but putting any real load on the battery will drain it very quick and if you don't replace the battery soon you could fry your alt. Make sure to get it tested somewhere to verify that's the issue. Link to comment Share on other sites More sharing options...
jmilch Posted July 17, 2011 Report Share Posted July 17, 2011 Yea I realized that when I posted it haha But how much would jus removing the cap do? Would it help at all? As people have said multiple times removing the cap will help. The cap really would only help in a vehicle with a beefy electrical system, not a poor performing electrical system. But you need to go have the battery tested and the alternator load tested to be sure neither of them are faulty.

HazeGrey75 Posted July 17, 2011 Report Share Posted July 17, 2011 On that low of power you have something wrong and its not just the cap! You need to go to autozone and have them check your battery and your alternator. You have a dead battery or a dying alternator Link to comment Share on other sites More sharing options...
tonedeaf Posted July 17, 2011 Report Share Posted July 17, 2011 Since it sits at 14ish volts with system off and car on, I heavily doubt it's the alt. The battery is jut discharging like a cap would. That or your power wire somewhere is grounding to the car shorting out the battery. You're gonna fuck up that amp if you don't stop dropping voltage that low.

michigancapri92 Posted July 17, 2011 Report Share Posted July 17, 2011 1. you most likely have a bad battery and you dont ned to get an xs power kinetic optima for 1000 watts. to keep it cheap get a good ole duralast battery, you dont need a pricey car audio battery for 1000 watts. 2. make sure the 4 gauge you have is not some k-mart, abc warehouse, cheap 4ga thats actually 8gauge, get a good beefy 4gauge wire and do your big 3 upgrade with a good 0 gauge wire, i like welding cable the best. and if you can run 0 gauge welding wire from the battery to the cap if you are bent on keeping it then 4 gauge to the amp. make sure the cap is SUUPER close to the amp and make sure ALL your grounds or very good. i have had good luck with the strut towers as grounds. 3. make sure all grounds are polished bare metal with an almost mirror finish. 4. check your alt it sounds like its good but if its not just replace it with a regular stock alternator, for 1000 watts you dont need a pricey high output alt a stock should be ok. so to recap, new duralast battery, good quality wire, good grounds, good working alt Teamcapri.comThe TeamCapri 1992 Mercury Capri XR22012 FORD EDGE SQ BUILDOld build logMy FeedBack1992 Mercury capri XR2 Hyper LED Link to comment Share on other sites More sharing options...

I think he misunderstood what resting voltage means.. I think you misunderstood what I meant. I was telling you his car is sitting at that, so the alt is charging. The battery just doesnt have the will to STAY charged. If the battery is at 14ish volts like it should be and instantly jumps down to 9 with only 700 watts of load, than the alt cant really be the issue (although not saying it might not have problems). I could play my car for quite a while with very little to no voltage drop with that amount of power. Link to comment Share on other sites More sharing options...

LT.Smoke Posted July 17, 2011 Report Share Posted July 17, 2011 WTF is everyone's issue with using a capacitor....That is NOT the problem...I would advise doing the Big 3 with some quality wire and check your ground ... I have used a cap for the last 6 years with NO problems If all else fails you could invest into a battery Team MaxRetribution Si Vis Pacem Parabellum Id rather be judged by 12 than carried by 6 Bowhunting- Life Begins and Ends at Full Draw Bowhunting Team Fatal Trajectory Hunt Team http://www.stevemeadedesigns.com/board/topic/49335-sick96vtecaccords-t-line-build/?hl=sick96vtecaccord << Accord Build http://www.stevemeadedesigns.com/board/topic/68498-smokedout08impalas-tline-build/?hl=+sick96vtecaccord << Impala T-line build Rebassed.com for all your music needs 👌 Link to comment Share on other sites More sharing options...
tonedeaf Posted July 17, 2011 Report Share Posted July 17, 2011 If you want it done right: 1-remove the cap 2-buy a high output alt 3-redo the big three with 0g 4-second batt other things to check: -your stock alt and batt -your connections across everything -check your ground again (factory bolts are not good grounds) -check the levels on your deck and amp I think everyone already hit all of that stuff though. Good luck man. If he wants it done right, people like you shouldn't be giving out advice... What are you, 14? Try reading once. The OP has a fucking 1000 watt amp man... Said before he had no issues with having the cap, which means its not the cap... Why the fuck would you suggest a high output alternator for a 1000 watt system? WTF!! I agree with doing the big 3/4 in 1/0 AWG wire... Again, why the fuck would the OP need a second battery? If you don't know what you're talking about, just don't fucking post... Sorry to single you out, but I'm so sick of seeing motherfuckers on here giving out shitty fucking advice. Not having a clue wtf they are doing... 1. you most likely have a bad battery and you dont ned to get an xs power kinetic optima for 1000 watts. to keep it cheap get a good ole duralast battery, you dont need a pricey car audio battery for 1000 watts. 2. make sure the 4 gauge you have is not some k-mart, abc warehouse, cheap 4ga thats actually 8gauge, get a good beefy 4gauge wire and do your big 3 upgrade with a good 0 gauge wire, i like welding cable the best. and if you can run 0 gauge welding wire from the battery to the cap if you are bent on keeping it then 4 gauge to the amp. make sure the cap is SUUPER close to the amp and make sure ALL your grounds or very good. i have had good luck with the strut towers as grounds. 3. make sure all grounds are polished bare metal with an almost mirror finish. 4. check your alt it sounds like its good but if its not just replace it with a regular stock alternator, for 1000 watts you dont need a pricey high output alt a stock should be ok. so to recap, new duralast battery, good quality wire, good grounds, good working alt I agree with most everything this guy said, short of polishing the metal to a mirror like shine... You don't need to do that... Lol... Just take it down to bare metal, sandpaper, grinder will work... Using good wire, he means get something that is AWG standard... And something that is NOT CCA... You want OFC... ^^ Link to comment Share on other sites More sharing options...
