Tigerboy Posted January 28, 2013 Report Share Posted January 28, 2013 hey guys, so im thinking about adding a second battery for extra power at my sub, i have a civic, with a stock alt thats 80A(i think) and an optima yellowtop d51r(38ah) so my question is if i add a second battery in the trunk, specifically a kinetik hc600, would it add draw to my alternator and require a HO Alt? im only running a 500.1 and a 200.4 for amps, but i get headlight dimming and some Vdrop. i was hopping i could just add the battery in the trunk by the amps and not need to upgrade the alt. Also if someone has a suggestion for a similar battery that is better for some reason please let me know. im looking to stay with something small, this battery is only like 10-15 lbs. Thanks guys -Greg Civic Build Trunk Build Log Link to comment Share on other sites More sharing options...
brad4021 Posted January 28, 2013 Report Share Posted January 28, 2013 a second battery would help have more capacity for you system but if you run them down from bumping hard it will take a little longer to charge them up then it would with just one battery. get the battery and see how it runs. if it seems like its not charging fast enough for you then look into a higher output alt. with your set up i dont think you will need a huge alt. i know a guy who has a mechman for his mazda 3 and it made a difference even with one battery.

8ight Posted January 28, 2013 Report Share Posted January 28, 2013 If you're running an AB 500.1 I would recommend a high output alternator because anything over 2000w RMS becomes quite the strain on a factory charging system. That being said your current alternator can charge 100 batteries, it will just take a while. I'm gonna hate Link to comment Share on other sites More sharing options...

Watch the bass Posted January 28, 2013 Report Share Posted January 28, 2013 Is it a 4 x 200 watt amp or a 4 x 50 watt amp. Your alt is tiny, if it´s the little math your system can draw 70 amp´s but in reality on music between 30-40 so you have only 40 amp´s for the rest of your car. Would be nice for you to have a bigger alt 120-150 amp´s.

Tigerboy Posted January 28, 2013 Author Report Share Posted January 28, 2013 yeah the Si comes witha 120A alt, mines the LX tho >.< sorry i thought the notation for the amps was total watts rms. number of channels, so to clarify, i have 50w x4 channels, and a 500 x1 channel. so 200+500 for 700 total. ill try it with just the battery and see how that goes. also i have a question about the 4ch amp, im only using 2 channels right now for the front speakers, and have no rears. i have the rcas unplugged from the rear channels and the gain down the whole way. so do i count that as drawing power or not cuz it shouldnt be using any power really like that.

The stock alt would get straight raped if it was.... i shook this one kids hand and it just folded in mine. long story short i fucked his girlfriendso.. yeah.. You want this to happen to you?
