Casper Netherlands Posted March 2, 2017 Report Share Posted March 2, 2017 Hello everyone i have a relatively mid powered system. I am having a issue with my electric system. I know this topic is being discussed million times, but I'm not sure what to believe. my system is as follows: pionner unit x2700bs 6.2" touchscreen pioneer gm-d9605 5 channel amp, 4x 75watts @ 4ohm and 1x 600 watts @ 2ohm (2000watts max) class d amp two nvx 6.5 speakers @50watts and two nvx 6x9 @ 55 watts, plus, two 12" rockford fosgate single coil@4ohm p1s4-12 connected in parallel for a final impidence of 2ohms, 250watts each, 500 -600 watts total 4 guage wire for + and - of the amp 14 guage speaker wires/ 8 guage amp wires stock alternator 110amps xspower d1200 battery big 3 upgrade with 1/0 guage wire from xspower kit All gains set properly with smd dd1 deck clips at 38 out of 40 but i never pass 31 my problem is that my headlights dims when the bass hits, and also i have voltage drops when the bass hits, at the battery terminals it goes from 13.8 to 12.5, or even lower. At the amp terminals its always 12.8 and it drops to 11.2 or lower. I also noticed a change of the engine noise, meaning that when the bass hits, looks like the rpms are affected or something, because the noise reduces every time the bass hits. I would like to play loud, but also not stress out my other electrics/electronics in my car. any suggestions? Link to comment Share on other sites More sharing options...

Casper Netherlands Posted March 2, 2017 Author Report Share Posted March 2, 2017 Do you think a more powerful xs power might resolve the issue? Link to comment Share on other sites More sharing options...
8ten8 Posted March 2, 2017 Report Share Posted March 2, 2017 If you're planning on keeping you car for awhile, save your pennies for a high output alternator and go from there. Your current battery is descent enough combined with a proper alt. You could purchase a larger battery/batteries but that's more like a bandaid.

Casper Netherlands Posted March 2, 2017 Author Report Share Posted March 2, 2017 Yes i am planning to keep my car for a while. I just don't like the idea of adding a battery, it will be an additional load for the alternator right? So yes i am considering on upgrading my alternator, but I don't seem to find anything that matches. I have a 2012 nissan altima 2.5s Link to comment Share on other sites More sharing options...
06RTCharger Posted March 2, 2017 Report Share Posted March 2, 2017 I vote alternator upgrade, big as you can drop in. Then charge ur battery up to top it off, or upgrade the battery also. I vote "against" upgrading battery without upgrading alternator tho. Just my noob 2cents. Link to comment Share on other sites More sharing options...

When it comes to car audio (and cars in general), people kindly remind me, you get what you pay for. Link to comment Share on other sites More sharing options...
Casper Netherlands Posted March 2, 2017 Author Report Share Posted March 2, 2017 Thank you guys for your support. Yes I also agree to upgrade the alternator. Does anyone have any link for altima 2012 2.5s? Just wondering if anyone has experience with this car and engine Link to comment Share on other sites More sharing options...
06RTCharger Posted March 3, 2017 Report Share Posted March 3, 2017 Probably gonna have to email the companies and ask for a quote for the 2.5 or fill out the inquiry forms available on the websites. Link to comment Share on other sites More sharing options...
ShadeTreeMechanic Posted March 3, 2017 Report Share Posted March 3, 2017 I would do an alternator and a battery in the back as close to the amps as possible. And a run of 1/0 front to back. If you don't have enough reserve battery capacity, the alternator won't be able to react quickly enough when the bass hits and you will still have voltage problems. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
