Yes in dB Drag I am street, but in IASCA I am in stock where I AM allowed to run the car, and I prefer IASCA to dBDRA any day. I wouldn't want an upgraded alt so much for competitions as I would want it for daily driving to keep everything up to par at its peak level.

An HO alternator would be the first thing i would do... How do you think a battery gets its juice, it doesnt matter how big your battery is, in fact the bigger it is the more strain it puts on the stock alternator. Just wait people, those alternators are not that strong. I have been in Car audio for a long time. (about 12 years)

suggested order of upgrade and more importantly, why. alternator comes last.

"It can be harmful if you see your headlights dimming darker, and darker, and darker each time... meaning your battery discharge exceeds your battery's charge time.
That's definitely a sign that your listening habits are warranting an alternator upgrade.."


It all depends on how you use it and how much amperage you are drawing.
This can also be seen if you are running too powerful of an amp for your electrical system.

I disagree with the cap being added before upgrading your battery or adding a second one. Batteries are about the same cost as a decent capacitor.

absolutely. true without a doubt, which is the point of why he said that. more evidence to support his claims.

as to the cost factor of cap versus alternator, its a crapshoot. read the article, It should state that they do different things, and each serves a different purpose. if you are buying a battery to cure dimming, a cap may be an easier alternative, and potentially better able to do the job.

but to those of us who want to watch a movie with the engine off, its much easier to see a cap would be a terrible way to do that!

a little off topic, but thats how I prefer to discern whether or not a battery or capacitor is more or less appropriate.

i'm doing 2700w with stock alternator (2x1200@12v D class + 1x300@12v D class..)
using a stinger 200a isolator, 3 farad cap and a 51R in the trunk..
only voltage drop running is at MAX volume..drops from 14v to maybe 12.5v and light never dim..

was initially worried about an alt. but as of yet see no need to really research it thoroughly

thats also because your audiobahn amps will only do the 1200 when theyre struck by lightning

slam dunk

Ludlam makes his point about overrated wattage on Amps. I guess if you took offense to him pointing out you're not getting anywhere near 1200 RMS, then so be it.
