Well, I used to have well over 5k watts of audio power in my old car, it was an easy deck out new deck in hook up for everything. Now since the Mazda 6 has a long deck, how has anyone customized audio? Is it harder or am I just so car dumb that it's blind to me?

Can anyone shoot me at a video or a website or even here on how I can get some bumping in my car or atleast something well. I could care less if I lose the bose or bypass it so it all works out.

HELP!
