Is300 Maximum Wattage For Stereo

AlienneilA · February 26, 2003

How many watts can my custom stereo be in my IS300 before I have to upgrade my alternator. I really don't wanna do that. I was gonna put in 2 Kicker Solo-Baric L7s with about 1500watts :o or 2 Kicker Solo-Baric L5s with about 1200watts. Can the stock alternator handle that much power? and would it mess up an in-dash screen? would capacitors let me do that much power without upgrading the alternator?

If the car cant handle that without upgrading the alternator i was gonna do one of those prebuilt audiobahn bandpass enclosures with about 600watts

Should be fine with either just make sure that you have atleast 3 farad of power caps in there aswell and I would strongly advise a deep cycle Battery

Do you all agree? Cuz I just don't wanna suck too much power and have my lights flash and I don't want to damage my alternator.

sod power caps - just get yourself a yellow top optima Battery and you should be fine - the IS's have a reasonable alternator.

coming from me who once spend nearly a grand on a streetwires 140 amp alternator - thats when they were that much

The power caps are still essential if you are running that much power and you don't want your lights to dim when the bass kicks in, even with a top of the range Battery I still have to have the POwer Caps otherwise everything dims out

a power cap is there to act as a cushion between the item that draws heavy current.....amp, and the Battery because it stores power it is the cap that takes the hit when the amp draws heavy current.

even a high end Battery would eventually struggle to maintain a constant level of available current if prolonged use of a heavy current draw.

and they look nice
