By not having a HO alternater. On really hot days i noticed everything heats up extremely fast and my subs keep cutting out all the time. but then at night time when its cooler i can actully play my system without a problem most the time. I have a 85A alternater in a 2002 galant with zx1500.1 amp with 2 12" kicker l7's. Everything dims like crazy i did order a HO alternater tho a 200A alternator for my car should be getting it in a week or so. I just hope thats the main reason why my system always cuts out thinking maybe my alternater now just cant handle the power and then just gets everything really hot and cuts out. Does this make sense??
also i no when alts get hotter they creat less power. so in the day its really hot so the alt doesnt make as much power so the amp isnt getting as much power so it cuts out sometimes. but at night when the alt is cool it makes a little more power cuz its cooler so the amp doesnt cut out...
yea that makes sense tho so im hoping its really just the alternator guess i will find out in like a week when i get it. Any other opinons would be great to
trey the amps is working great. Im only running it at 4ohms though cuz the 2.5's wont handle anything more. I bought a 9515 that is gunna be powered my the P3000.1 it should be here by the end of the month. But ya i love the amp does a rly good job.

do u think the hotness of the alternator affects how many amperes it puts out?
Its true. I read it somewhere, but yeah there is a reason. Also you can test it out. I do notice that on hot days I get less amperage out of my alt, and on cold nights/days, I get less voltage drop.
HO alternator should fix that right up. If your alt is rated for 85 amps, it may only do half that at idle, meaning your drawing WAY more power that it can supply.
And yes excessive heat can reduce alternator output a little. Cooler is better, to a point.
a quick two cents and only goin by my basic knowledge from rc motors which are built much like a alt. what i'm seeing it like is this, there is coil woundings that spin on a shaft generating your power. on hot days those windings expand creating friction and drag. on the hoy days it heats up causeing power loss. when cold they run at thier average temp and everythings peachy. i also feel that like a computer it can run better hot meaning average temp hot. and to cold can take away power to. thats just my opinion, hope this sheads some light on things for you.
