[QUOTE="Blackout67, post: 8924285, member: 683415"] Im not saying you never need an HO. I just dont need one in my case and 95 percent of people will not need one either. Your sons trucks lights aren't dimming because he has a red top battery that is many many times the capitance than a measly 5 farad. 5 farad when you do the math is going to (under perfect circumstances) be able to discharge 100 watts in around a second. Thats pathetic. Not only that, but it goes directly against your statement regarding putting "stress" on the alternot by adding a other capitance device to the circuit. A capacitor serves the same function as a battery. It holds a static charge to be used later, it doesnt generate power so it will constantly be needing to be charged because it is such a low capitance, in the face of a 2k watt system without the red top would constantly be drained providing negligible gains. Also no one here is saying youre some backwoods installer, or atleast not that ive read. You say in your experience but we are also here saying in our experience. In my experience it is not worth the hassle and price of ordering an alternator for $350+ and waiting weeks for it to be built and shipped and potentially have to rip apart the front of my car to get to the alternator (ive installed HO alts on a Focus, it is MISERABLE) than to just add an extra battery into the circuit especially when im running a system that will barely exceed the stock charging system. I dont sit around idling at office buildings making an enemy of myself to the public and I dont sit there and listen to straight bass sine waves. Speaking from my experience of installing systems in the same exact car, I do not need a HO output for this barely 2k watt system im pushing. I dont. I dont think your son does either with thag red cap and a system of that wattage. Again all we are saying is that its more complicated than saying you need HO alt and AGM and a capacitor. Does it work? Sure do you need it? Absolutely not. Will buying a $80k truck to commute to your office job work? Sure. Do you need it? Absolutely not PS. The cars electrical system is designed to support the max amperage load of all circuits. How often are you driving around with all your accessories running at full tilt? I never do. Hell i rarely use my AC. If your voltage is fine youre good. [/QUOTE]
