Do you know of high output alternators that don't cost $550 a piece like Mechmans? yea there are some out there, as i have bought a few others before, but for what its worth, i ordered a mechman yesterday haha, so that should say all i need to say about that. and for your power, you really shouldnt need a HO alt, just look into a nicer battery and the big 3 as a solid foundation. also, make sure ALL of your grounds are good. a weak ground can really affect dimming, voltage drops, etc Quote 1969 Chevy Chevelle 20/22" staggered Bonspeed Huntingtons wrapped in Nitto INVO's Mechman 250amp cs144 alt w/AVBM Kinetik 1800 main battery/Kinetik 2400 in the trunk Pioneer AVH-3200dvd Headunit (2) sets of Hybrid Audio Technologies Imagine components up front (2) DD 3512's d4 coils Sundown sax100.4 component amp Sundown saz-3000d subwoofer amp 5ft^3 box tuned to 34hz MY BUILD Link to comment Share on other sites More sharing options...

Dylank811 Posted July 15, 2011 Author Report Share Posted July 15, 2011 (edited) Haha it was the only point I could find that seemed stable enough after building my amp rack, but don't worry it's not rigged. The spot really should be fine. There was a reason I put it there, just can't remember now. There are some other things that I think are effecting it more than that.

dyeagain15 Posted July 15, 2011 Report Share Posted July 15, 2011 Ok so you're running an extra load on top of the normal loads your car runs. There will be a dip in power. Without electrical upgrades i.e. a bigger battery or going crazier with a H/O alternator you will notice voltage drop. I put a Shuriken battery in my truck an noticed better performance out of my audio. Your battery is probably what, 700 CCA? If that? I've heard of 1 CCA for every rms youre running. So my suggestion would be upgrade your battery to what rms you'll be running plus some reserve for extra loads in your car such as lights and what not Quote My F-150 Build (So Far) 2 DC L3 10's Kenwood KDC-X794 (4) Selenium ST200 (Highs) (2) RE X8 (Mids) Sundown Sub/Mid/High Amps Shuriken Batteries Knu Wiring My Feedback Thread Link to comment Share on other sites More sharing options...
LoudBimmer Posted July 15, 2011 Report Share Posted July 15, 2011 I'm running 1200 wrms and my voltage does not drop below 13.5v but I'm still adding kinetik hc1800. Quote Link to comment Share on other sites More sharing options...
Dylank811 Posted July 15, 2011 Author Report Share Posted July 15, 2011 Okay cool, so here's what I'll do: Next paycheck, I'll go grab some 1/0 AWG wire and knock out the big 3. I'll look into a new battery for my car, and maybe I can get one within the next month. I'll also investigate my ground and see if I can find a more suitable location for it, if my problem persists.
