installation problems

[laurenk]

hey everyone.. i have a 2007 mazda3 and want to put my 15 inch subwoofer and amp in it while keeping the stock system. but, I have no idea where to begin or what I need. i've never done this on a newer car like mine before, so I was wondering if someone could basically walk me through this or if there's a 'how-to' page out there. thank you.

It would help if you tell us exactly what amp and sub you have.

powerbass 15 inch sub and a crunch amp.

hey i got mine this way... we put a crossover thing from the left rear speaker wich converts it to a rca output got a switch in the front so i can s*** off the subs whenever i want and well the rca goes to the trunk and to the amp then to the subs but yeah thats how we did mine to keep the stock stereo
