Voltage Stabilizer

[ACE-tC]

Hey guys i just bought a japan style voltage stabilizer. does anyone know how to install it. iv'e seen a vid on youtube but the guy has a grounding unit do i need one too? The stabilizer hooks right up to the batter i know that much problem is i dont know if the connection with the black tape goes to neg or pos. can someone help me out?

Voltage stabilizing and grounding kits are NOT required or even needed on the tC. Only under heavy electrical loads from audio amplifiers, neon kits, and airbag kits would you tax the OEM system enough that it would make a difference. As far as engine performance goes, the 2AZ-FE does not rev high enough where these products would make a benefit. If you had a built, F/I motor revving past 7500RPM, then a grounding kit would be warranted.

This is not all smoke an mirrors. On older cars or cheaper quality cars where there is insufficient sized electrical systems, both of these kits would be a plus on lightly modded cars. Scions are well designed and built automobiles. The electrical system was designed with enough headroom to handle most of the upgrades that people would be adding to the system. There is a point though where the capacity of the alternator, battery, and factory wiring will become inadequate.

BTW... The Voltage stabilizer kits are the same as large capacitors that you see on large car audio systems. The differences are that the stabilizer is encased in a small enclosure and designed for the engine bay but of smaller capacity caps. Provides the same benefits of voltage buffering that capacitors provide for amplifiers except for the entire electrical system. The grounding kits are nothing more than large gauge power cables with a central attach point. Achieve the same results with quality 4GA car audio power cable.

What brand is your voltage stabilizer? Some models connect in series with the battery and some parallel to ground. It depends on the internal circuitry of the unit. Also, there has been a flood of Chinese "knock-offs" on the market within the past year. Buyer beware as some of these poorly designed units either don't function at all or can actually become a load on your system with detrimental effects.

um the brand is some asian brand i got on line a while back but i had it checked and it was good. i have alot of things hooked up to the battery right now as well like the grill lights, interior neons, and my new system that i will be getting soon which include a 600-700 w amp and a 1200 w (2400max) 15" sub, should i take the stablizer out or just keep it in?

As Navy said and I will also, a voltage stabilizer is not needed. When I first bought my tC I had someone tell me to get one, but I did further research and found it did nothing and I wouldn't benefit from it. Dude, don't waste your time and energy w/ it.

Take the stabilizer out and have your wiring redone. You'd be a lot better off having your wires tapped into the fuse panel next to the steering column. Going through the fuse panel gives you a safer path and a fuse to back everything up. If you don't know how to install it in the fuse panel, ask a wiring specialist and they'll know what I am talking about. Plus all the wires running off your battery looks very sloppy. You want all your wiring hidden away for a cleaner look. If you look at any of the pics of my tC, the only wires you'll see is the 0 gauge wire for my sound system coming off the battey as well as a 100+ amp fuse to back it up. Neons and other things are hidden away and not hooked up off the battery. Not bashing you, just would rather see you have a cleaner looking ride and have it done the right way, less chance of shorting out or having a fire.

OK. Round two with my stupid PC laptop and stupid Windowtwit OS.
My long oration was obliterated so you now get the skinny version.

Are you looking for voltage stabilization that supposedly increases engine performance or something that can increase the capacity of your car's electrical system when it comes to I.C.E.? My original assessment was based on that of engine performance but since your last post, I believe you need the latter.

What you most likely want, and with the addition of the amplifiers, need would be a minimum of a 1 Farad stiffening capacitor that is made specifically for high draw audio amplifiers. While a stiffening cap can be considered as a simple voltage stabilizer, it will by no means provide any increase in engine performance. Same goes for these voltage stabilizers on the market when it comes to our cars. Reasons stated on my previous post. There are other cars, namely older cars, that had poorly grounded electrical systems. These are the cars that a properly made voltage stabilizer and a grounding kit would benefit. On the flip side, there are some voltage stabilizers out the with large capacitors in them. These caps charge/discharge rates are not quick enough for the constantly changing needs of an audio system.

Check out this website, Jacobs Electronics Jacobs Electronics has been around for a long time and a favorite of hot rodders tearing up the track. The Race Accuvolt is meant for racers who run without an alternator. The Audio Accuvolt is more inline to what you might be looking for. Before that, you might explore a larger battery, stiffening cap, and possibly the 20% overdriven alternator pulley available from NST.
