I decided to replace my bose system in my car after about a year of thinking about it. It sounds really good for a factory system and for those that don't know, yes, you can put in a aftermarket radio while still keeping the factory speakers and amp and everything still works perfectly. I replaced everything with pioneer d series speakers, 4 inchers, 5.25 components and 6x9s. I also got a pioneer 4 channel amp and a new pioneer radio to replace the older pioneer unit I had. It sounds great but I got to have subs now lol. I just ordered 2 pioneer TS-W310D4 12s off ebay for a pretty good price, $125 for both with free shipping. I also ordered a pioneer gm-d9601 amp. Yup, my ENTIRE sound system will be pioneer lol. Here's the vid.
