Alpine Subwoofer Installed!! I just got around to installing my subwoofer in my Prius C 4. It took me about 3 hours to finish and get it set up just right. I mounted the sub in a cheap sealed enclosure which im planning on upgrading sometime in the future. I think i might make one myself if i find time for it. It sounds amazing, i love it! It moves my rearview mirror out of place if i turn it up enough. I will take lots more pictures tomorrow of the setup, for now i only have one. Ill also upload a video so you guys can see for yourself how great it sounds :rockon: I mounted the amp to the backseat behind the sub and ran the wiring through the seat to the battery. I was going to mount the amp under the styrofoam inserts but i didnt feel like cutting out parts of the styrofoam. I used industrial strength velcro to keep the Sub secured. Sub: Alpine Type R 10" (SWR-1043D) Amplifier: Alpine MRP-M500 For my next project i am planning on replacing the factory speakers or installing black rims.
