I've heard from a friend that i shouldn't get the whole set of Unorthodox pulleys. I should just get the crank pulley. Which is fine if i get it. But i read on the site that:

If the stereo system in question is above that wattage amount then the owner has two options. They can purchase our stock or oversize diameter crank pulley or we can make a custom alternator pulley, which will be smaller in diameter and will increase the voltage output.

Capacitors are a smart addition as they store the power the amplifiers need for peak draw. Our stock diameter series used with capacitors allow the vehicle owner to achieve the cleanest and most powerful sound with no loss in voltage output. Another good option would be to install a second battery or batteries just for the stereo.

I have 1 KICKER SOLOBARIC S 12 L7, and it gives out more than 600 watts rms. I have 750 RMS. and i even plan on putting another SUB in there. What should i do?

 

Follow what the site recommends. If you're upgrading to over 1200 watts you should definitely not get the underdrive crank, you will see performance loss for your audio system.

 

Just get the standard size lighter pullies, you will only lose like 1-2 hp over the overdrive pullies.

 

Get the Ultra Sc 12 Volt Supercharger pulley. It is the same diameter as the stock crank pulley and will not underdrive the system. I have them for $180 shipped if you want one.

 

What do you mean. im worried about my lights dimming, because im gonna have a lot of power to my speakers. and i just want a crank pulley. what is the Ultra SC, i dunno which one to get. and if i could get it it without buying another battery.

 

The Ultra Sc crank pulley is the same diameter as the stock crank pulley. This means you will not underdrive your alternator, which happens with the Ultra S underdrive crank pulley.

 

so get the Ultra Sc crank pulley. and it wont mess it up wit my sound system.

 

thats right!

I just ordered the underdrive crank pulley, can't wait

 

Yes, I have a system in my car as well. I currently have the Ultra Sc pulley set installed.

 

wow what kind of system do you have. they say it can handle up to 600 watts rms. i have 750 on just one amp, and im gonna get another one. i just wanna know if its fine.

 

I have about 900 watts RMS.

 

if you get the Sc pulley, you will essentially be stock. so run your system as if your car is stock. if you need caps or batteries later on, it means that your alternator just cant handle the load.
CONCLUSION: If you want a crank pulley with no adverse effects on your electrical system, get the Sc 12v crank pulley that excelerate offered!
