I'm already too deaf at my age to do the car stereo thing again. I had about $5000 into mine back when i was like 20-21 and for a few years after that. I used to have, in my 96 dodge neon, 2 jl audio 15" subwoofers, running on the original rockford fosgate punch 200. I remember i had a clarion head unit, sony 4 way 6x9's in my rear deck, sony 6-1/2 in my doors, and 1" dome tweeters in my dash, of course a bunch of fuse blocks, a full cap to help prevent battery drain, and all kinds of other wiring and stuff. I do miss it sometimes,it was loud as **** and blew all of the seals in my trunk, doors and such back then. I also had to re-glue my rearview mirror back on in more than one occasion. Now i have an 09 hyundai sonata v6 and the factory stereo and my ipod are plenty enough for me.
