Silver Member Username: BlainewPost Number: 406 Registered: Nov-05 | what would happen if i just didnt get a HO alt. would i just not get full power of the amp? |

(wrong), really all what they do is provide a serge of power when your amp hits, but what i don't like about them is when a capaciter discharges it basically fully discharges and your alt. has to charge it back up before the next big hit, so it is constantly charging and discharging, which inturn makes your alt have to push out the amps, then stop then push out amps,push out the amps, then stop then push out amps... ect. that will lead you alt to fail after time, in my opinion if you have the room, wire a second bettery (DEEP CYCLE) parrallel with your cars stock battery, the second battery will provide the power needed to hit consistanly, and it acts as a 'current pillow' for your alt. so when your amp hits it will pull mainly from the batteries, and your alt. will only have to put out a consistant amount of amps, were with the cap you alt will be consistantly fluctuating amperage. i have a stock alt. in my 99 dakota. i have never had to replace my alt. and have been pushing 1600w for 3 years now threw my 15" |

Silver Member Username: FandimReno, Nevada United State... Post Number: 548 Registered: Jun-05 | Chris, I'm not trying to be offensive, but your post is completely inaccurate. If you're not 100% sure on the information you're giving out, please, just remain silent. Adding a second battery in paralell will not fix this problem, it will, in fact, make it worse. What's going to happen is, you will still be drawing more power than your alternator can provide, and it will just take longer to notice the voltage drops. But then, it will also take twice as long to fully recharge them, which means your alternator is gonna be working a LOT harder. Also, about the post regarding your alternator starting/stopping/starting/stopping, etc... Uhmmm... Care to explain why you think it would do that with a capacitor, and not a battery? The power is coming from somewhere in either situation, so I'm curious to hear about your logic. Third - a second battery dosnt give your alternator a cushion. All power drawn will come from your alternator first. If you have a good alternator, your batteries wont even get touched. If the current was drawn from your batteries first, then your amp would always be getting a 12v charge, instead of the 13.8-14.8 an alternator provides. Chad, I recomend going to www.excessiveamperage.com. I got my HO alternator from Nathan (200 amps) for under $300, after shipping. Had it in less than a week, too.. (and he lives on the opposite side of the country I do, to boot.) Now to get a bit more technical, the reason you cant say a 2nd battery is similar to a big capacitor, is because a batterys ESR (basically a measurement used to determine how fast something supplying power can actually supply that power) is MUCH higher than a capacitors. If you're getting a cap, try to find one with an ESR of .0015 ish. Now, the argument about if capacitors actually help the sound? I'm not going into that. I really dont know, so I'm not going to even try to pretend like I do. I dont hear a difference really in my car without any capacitors, and when I use over 15 farads in low ESR capacitors. Check out this example, it's a simple one really.  So, no matter how big your jar is, if more water is pouring from the leak, than the faucet, sooner or later, it's going to catch up with you. Adding a 2nd battery is like adding a 2nd jar to the equation. Only thing that's really going to fix the problem, is adding a HO alternator, so your glass dosnt empty. Two flaws in this example, is that with your cars electrical system, the water would be drawn from your faucet first, then the jar. But for all intents and purposes, its a good example I think. 2nd flaw being, the more your battery discharges, the lower it's voltage (Yellow top optima's are pretty good at remaining 12v through the duration of their discharge, but most batteries are not). |
