mmacleod1983 Posted October 15, 2015 Author Report Share Posted October 15, 2015 http://s864.photobucket.com/user/mmacleod1983/library/ Ill try to update with more pics. But you can see the battery terminals are corroded to shiznit and my battery gauge goes into the negative pretty far never used to do this. when I start my truck it will go into the positive slightly but at stop lights or idle its in the negative Link to comment Share on other sites More sharing options...
reedal Posted October 15, 2015 Report Share Posted October 15, 2015 Clean your terminals off. You can use some Coca-Cola and a wire brush. Make sure you get both sides of each connector, then put dielectric grease everywhere metal touches metal, and then on the top of the top connection. If you're not dropping into the 12's, you really don't need to worry about your voltage too much. You're not hitting battery resting voltages. Just make sure you keep your connections clean SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
Miguels Posted October 15, 2015 Report Share Posted October 15, 2015 I think the problem is the terminals. He said he hammer them so chances are they are loose my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

reedal Posted October 15, 2015 Report Share Posted October 15, 2015 Good. You put some dielectric grease on there?

mmacleod1983 Posted October 15, 2015 Author Report Share Posted October 15, 2015 just went to town and bought some. took terminals off put a few sprays on posts and a nice fat layer over everything else. Noticed an improvement slightly in my bass response But I went ahead and ordered a new battery. I think that is the culprit. Im getting a steady supply of voltage around 13.89.13.96 big bass it drops down to 13.40 or so. Either way... 13+ is good I supppose and now I know everything it tight and done proper Went with the XS D4800 came out below budget too Just gonna leave the stock alternator and see how she performs. Im only pushing maybe 1300-1500 watts probably more like 1000 but amps are rated at 500 rms at 2 ohms at 14.41 volts I have two sub amps and a 300 watt amp on the highs Link to comment Share on other sites More sharing options...
Esgedi Posted October 15, 2015 Report Share Posted October 15, 2015 This is a strange theory, but what sort of vehicle are we talking about here? As the owner of a Trailblazer, i know what it's like working with a vehicle that has a strange system in place for battery charging.My theory is what controls your alternator uses an algorithm for battery charging that might monitor battery charge rate, and when you went to bigger cables it needed to send shorter pwm signals to keep the battery at it's programmed voltage window, because your old cables had significantly higher resistance. This computer might also monitor each pulse sent out vs the raise in battery charge, which could affect the charge voltage, amperage, and pwm signal considerably. If this computer sees a more "ideal" result when monitoring this, it might back off the voltage it sends out.If this was the case, i wouldn't be surprised. What are you using to monitor your voltage, btw? If it's the dash gauge, a whole host of things could affect that. Mechanical ones can be notoriously inaccurate when you change the factory electrical setup. My recommendation would be to buy a $5 harbor freight/walmart DMM, extend the leads with some speaker wire, run around the edge of the hood, into the cabin, and monitor your voltage that way. Compare that to your gauge, worst case senario you end up with a DMM with really long leads that can be hardwired into something. Don't trust a shop but you personally just smoked two decks, makes sense. 03' Trailblazer LTDayton Designer 6.5"s & Silkie tweetersDayton Audio Ultimax 18"Pioneer 9601 & 8604XS Power D34002 runs 1/0Singer 250 Link to comment Share on other sites More sharing options...

All I know is my lights were dimming after I added a second sub and amp. I upgraded to big three I have now ordered a new battery (hope this solves my problem) I used a volt meter from wal mart and tested voltage at amp, alternator and battery posts all remain prettty constant at 13.76 on big bass and up to 14.21 in between I seem to have eliminated the clipping though so im happy I believe the cheap battery that was fine until the new current draw is the problem New battery should be here within the week ill update how she performs 2004 dodge ram btw Link to comment Share on other sites More sharing options...
