- if you are trying to use the factory sub and just go with an amp, think that would be possible, (based on what i have seen). Check out
http://www.crutchfield.com and you can take a look at their selection there. Whatever model you see that you like, you may want to get that model # and shop around to see if you can get a better deal.
Keep in mind that there are subs that'll fit in the factory enclosure. The Bose system is good, but it's not great. Especially once you add that after market amp to it. Good luck with your decision and maybe one of these audio pro's will chime in to give a different opinion.
