is it me or does the s2k just make alot of engine noise? im getting the engine noise interference and the stereo shop told me it is because i wired the rca's wrong...but when i routed the wires outside the car, i still get the noise...they also suggested i change out my battery since i have an 01 and havent changed the battery yet...any others out there with a suggestion or solution? as of now, i just added PAC noise filters and this help significantly but im hoping to find a better solution...thanks

 

Check here:

Explain how your car is wired. I'll try and help you. Sounds like your shop hasn't worked on to many S2K's. I have '0' noise in my car.

 

wait... you have pioneer 8600mp... That radio is problem radio.

I had to replace 2 pioneer 8600mp at my shop (actually my dad's) because of the RCA output was defective. You might want to get that checked if everything else fails.
