- 2008 Mazdaspeed 3
I have a 2008 mazdaspeed 3 gt with the Bose audio system. I would like a little more bass so I bought a 250 watt 4 channel alpine amp to hook up. Just curious on what some people have done to hook a aftermarket amp up to a stock radio head unit. In the past I used a scosche box to plug RCA cables in, but I don't want to have to cut into the stock wiring harness. Thank you
