1500d power setup

[ener.g 0]

I have 2 1500s coming to me and before i install them i want to make sure that my electrical will handle it

right now i have a stock alternator on my bravada (blazer if you will) pushing ~110amps and 1 yellowtop optima

my plan was just to replace the stock alt with a 300 amp one but seeing as these amps can be run at a higher voltage than 14.4 i was thinking of doing dual alts and running 16 volts on a 300 or 200 amp alternator (whichever is reccomended) and have a seprate battery in the back

I would like to get as much power from them as possible so i will most likely strap them @ 1ohm (i know its not covered under warranty)

I just need to know how big of an alternator i will need to run them like that and if running the amps at 16v daily is gonna be ok

so many options, but what will do the job?

Thanks,

Scott

I would never run a amp 16 volt's daily. get a bigger alt and a couple more batt's in the back and the amp's will love you for it. if you need more power get more amp's . the higher voltage is just one more thing to go wrong. good luck

The only problem with 16 volts daily is that your alternator needs to be charging at around 18 volts. It is the 18 volts that is hard on the amps -- they are fine for comps with that, but 18 volts is alot to ask daily, especially for the large power supply caps.

well, thats the reason i asked before i do things lol

so with 2 of these amps will a 200amp alt be enough with 2 yellow tops

or will i need the 300amp with 2 yellowtops

A 200 amp will work fine. A 300 amp would be better, but not necessary.

Now would a 200 amp with a higher idle amperage be better than a 300 amp with lower idle amperage? I barley drive my car and when I do I rarley have the RPMs over 2k.

[sundownz 197]

I always prefer higher idle alternators as much of the time your RPMs will really not be very high at all, even at 45 - 55 mph.

thanks for the responses, i think i may go in between and get a 250 amp.
