Stereo & Electronics - ? about Monsoon amp and wiring harness

I just had a new HU,sub, and amp installed. I am selling the old Monsoon HU and 12 disc cd changer. The guy I am selling it too asked if it includes the amp. I am guessing that the stock amp is still in the car since the ppl who did the work never gave it back? All they gave back was the old HU and changer. Also, he asked if the changer includes the wiring harness. Is this just the harness that held the changer in place? Thanks

Was it factory installed? Or a dealer add on. <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" /> <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" />

I'm not sure. How would I find out? BTW, how does it matter? Just wondering. thanks

If it was added on the changer cord was just ran under the plastic trim. If the factory did it would be taped with another harrnes. <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" /> <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" />
