Dustin, again I am not sure about the 190-- I can only speak on my 300e. The amps were located in the trunk up on the top "hat rack" or rear deck. I ended up just running bran new speaker wires which was FAR easier than adapting the factory active bass amps to my setup. Loose connections and frayed wires are kind of tough to see visually, plus the amps/HU might be corrupted from the inside. You can go the factory Becker route if you are concerned about a stock looking interior, but any aftermarket head unit will be much more beneficial/functional
