Nathan at Excessive Amperage has quoted me $299 for a 160A direct bolt-on alternator for my 4-Runner. Mr. Alternator has a 150A for $210. I have two questions:
1) Is the extra 10A worth the extra $90?
2) Are either of these gonna be enough? I'm running a KX1200.1 @ 1 ohm (1490w on birth sheet) and a KX450.2 @ 2 ohms (460w on birth sheet).
I'm a little worried that neither of these is big enough. Nathan can build me a 200A for even cheaper than the 160A, but it will not be a direct bolt-on.
the general rule of thunb is for every 100 watts of power an amp produces, it uses 10A of current, or so i think. so if your amp does approximately 1500 watts, it is pulling or trying to pull 150A of current alone.
Yeah, the 10A for every 100w is what has me a little worried. On the other hand, I won't be driving around alot with my system cranked, so I'm wondering if these alternators will be sufficient.
Anyone else?
I sure wish Toyota had put a larger alternator on these things! It's much easier to find a bigger HO alt. for a Chevy!
Do you think the extra 10A is worth $90 from Excessive Amperage?
The only times I would really "crank" my system would be to show someone what it can do. I certainly won't be riding around with 1950w RMS blasting me away while driving.
I just want to be sure this 160A alternator will be adequate before ordering it. I'd love to go with the 200A, but I'm afraid it would cost me an arm and leg to have it installed.
Any idea on what kind of installation costs I'd be looking at? I know a 200A would require bracket mods, and Nathan said it would also require some slight wiring mods.
help!!this was the most relavant topic so... ok can anyone give advice...what is the best way in providing more power to ice inside a car, the alone car battery provides power but may soon drain down when the amps,subs,tv's etc are on, is there a simple way off adding more power avaiable to the ice system, iam thinking an additional battery or upgraded alternator? thanks.
wait, you all aren't factoring in the original 60 amp alternator. If the 160 amp alternator or 150 whatever, runs the system that would leave the 60 amp for the car, correct?
