bergi85 Posted April 14, 2010 Share Posted April 14, 2010 The factory amp is NOT underneath the passenger seat, trust me I just looked on Monday. The only thing under the passenger seat is the subwoofer, thats it, just the speaker. I have been going through this forum now for 3 days straight and it seems that the factory amp is behind the back seats almost by where the spare tire is, but closer to the back seats. The details are on this forum, i just can't remember what page. Quote Link to comment Share on other sites More sharing options...
lenore Posted April 14, 2010 Share Posted April 14, 2010 It is located behind the rear seat. You have to remove the rear seat for access....It is located about middle,between the tire well and bottom seat cushion. Quote Link to comment Share on other sites More sharing options...

Yes that is excactly what I was looking for, this link needs to be pinned, it seems that a lot of people are looking for the amp in the 99-03 RX's.
