Hello,

My 03 Mustang came with a sound system Mach 1000 with 2 big speakers in the trunk and 4 amps, I also have HID kit installed on that car.
My question now.

Will UDP effect any of this? Will the battery die from all that stuff?

Will UDP help a lot with gas and performance?

[2002 BLK GT]

That's the oem feature bro... There's a difference between mach 1k amd mach 460. and yes the udp will be okay with that you have.

[bloodusmc]

OK whats a good UDP to buy.


BTW THE MACH 1K is very good.

The steeda ones are good if you need help on the installation let me know. Oh wait they don't say that fit your v6. 1999-2004 Ford Mustang Underdrive Pulleys at AmericanMuscle.com - Free Shipping!

Yes I know but I don't think that is better than my custom sound system lol.

[bloodusmc]

ok so the steeda dont fit the 03 V6?
so what is the next good one that will work ?

that is soooo much easier than the pulley swap on my GTO lol

[2002 BLK GT]

A 3ft breaker bar will be better or a ratchet with a long pipe will work, I believe you will need a different harmonic balancer since yours its 03, PM amnick about which one to buy

[winnie51189]

Just check your harmonic balancer, if the face of is flat then get the 01+ if it has a raised area get the pre 01. The 00's should be the only one that need to double check the balancer since that's when they switched the design.
