ML 430 Addition of an amplifier for subwoofers

[doctorescobar]

Has anyone installed an amplifier and subwoofers in the ML 320 or 430. How can i hook up the amp to the factory stereo ? Is it possible ? I have done plenty of aftermarket stereo stuff before, but never with a factory stereo. Any feedback would be appreciated. Thank you, and i will try to answer your questions too.

find the amp to the ml which should be located in the dashboard on the drivers side. locate the speaker outputs to the rear speakers, splice into them and insert a high to low converter so you can use the output for your amp. most amps have a built in cross-over that can be used to turn the output of the amp to a low level for the sub to use. :D
