I am thinking of getting the new cvx and running it at 2 ohms and my amp will give me 800WRMS. That will KILL my stock alt right??? I think the stock alt put out between 110-120 amps. WHAT IF I dont set the gain to 4V(my preouts are rated 4V) What if I set the gain low, will that help?
I have heard people say that they have hooked up 1000 wrms or more to their stock alt and they were fine. I would personally never hook up probably more then 700 wmrs. Just becuase of what COULD happen. But impatience gets the best of most people, and they want to just hook it up now!
If the preouts are rated 4V, that does not mean that HU gives 4V RMS. If you actually measured it, it would show about 2V and sometimes it would only peak at 4V Yes, the low gain will help, if it's set below the HU& match point. The amp then will not give it's rated power and it will draw less current than it can. 800W RMS is not too bad on stock alt, however, your alt is pretty small (110-120)
How many people have had somthing FRY or EXPLODE because of hookin up 1000-1500 watts on a stock alt? Never heard one case. Maybe on really old cars, but on the newer ones? like 1995+? i doubt any big issusys
Jeffrey, read this, straight from glass wolfs site:
"Everything works perfectly so long as the power requirements of the vehicle do not exceed the capabilities of the alternator. If the peak output is surpassed due to excessive load, then power will be pulled from the battery. If the alternator and battery combined cannot meet the demand, then the vehicle's voltage rails, and subsequently the electrical devices are diminished (dimming lights, spark plug misfires, audio distortion and amplifier clipping, or even the car stalling.)"
I've had one alt fail. It was 75A, in a car with fairly demanding stock electronics.
I started customizing the sound system when it had about 150k on it. Originally with just a few hundred watts. By about 180k I had 1000w rms in it, and eventually upgraded to about 1200w. Finally at 226k the alt died. No "frying", no "exploding". I just noticed my voltage not recovering one day - and the next day there wasn't enough battery to turn the engine over.
Replaced that 75 amp alt with a USED 110A and it's run fine ever since. Coming up on 265k. Never seen my voltage below 13v.
Still on the same battery, too. Should be about 7 yrs old by now. My only wiring mod is an 8 ga about 18" from the alt output to the battery (+).
Im running 800 watts rms on my stock honda accord alt that only puts out 80 amps. I reccommend you get a capacitor and an extra car battery and you should be fine. You shouldn't listen to your system with the engine off. When I do I turn of my subs so it doesnt take so much juice. Go ahead and do your install.
Something is wrong with my alt or something. Last night I really noticed the lights dimming, took a closer look and they were dimming pretty good, and the dash lights were dimming too. Either Grillz takes alot of power, or the alt is failing.
