I was going to add a little amp and sub for a little extra bass since the factory Bose system sucks. Does anyone know where the best place to get signal would be? It can be either RCA low or high level input.
Passenger front kick panel is where the Bose amp is. You can grab high level out, think the low level is very low and you would have to crank your gains. I did not verify that yet though. http://www.atenza.mazda.co.jp/comfort/img/equip_img_01.jpg
