PyROZen Posted January 10, 2005 Report Share Posted January 10, 2005 also depends on your battery, right now I've got some crappy $35 "Extreme Energy". I'm only running like 200w and my lits dim quite noticably. I feel for my car every morning when it starts up. Link to comment Share on other sites More sharing options...
Bing_0 Posted January 10, 2005 Report Share Posted January 10, 2005 if your electrical system is in good shape, should be fine.most likely, unless you are going into SPL compes, you arent maxing out hte amps out the time, and if one is a mid/high amp, then definetrly its not being used to its max potential my vote is that as long as you use correct wiring and the batt and alternator is good, you shoule be fine. b Link to comment Share on other sites More sharing options...

Boomin850 Posted January 11, 2005 Report Share Posted January 11, 2005 well, I'm running a http://www.cardomain.com/item/ABNA2200HCT amp and an old 5 channel KAC-859 http://www.carreview.com/PRD_49615_1806crx.aspx along with 2 voodoo capacitors. The lights don't dim anymore but I'm scared that the alternator will go out soon. -MIKE Link to comment Share on other sites More sharing options...
