Sound/Tech Question.. Big stereo's and underdrives

That's really not that big so I don't think you should have any issues. I'm running 1500watts in mine without any dimming issues.

Those Steeda underdrives don't underdrive the accessories that much.

I would say it depends on the amp, setup... I have a rockford fosgate 500A2(circa 1999-2000) That puts out 500 watts rms@4ohms And I am running two rockford HX2 dual voicecoil subs.. When i only have one going... no problems with the lights, but when i want it louder and put the other one in the lights dim pretty badly..(you can see it on the car in front of me) I guess it depends on the amount of draw your amp can pull..(mine is up to about 100 amps??? i think) I am supposed to be running at least a 1\2 farad capacitor in my setup...but I am not...

Putting my Steeda u/d pullys in this weekend. I'm running a P.G. 1500 and 500. I'll let you know what happens.
