A complete re-wire would only make sense if I wanted to completely replace the stock system, which I don't. Not all stock systems sound terrible. Mine actually sounds half-way decent. I would have to drop a good $500 or more on component speakers and another few hundred on an amp to get a noticeable improvement. Throw in a subwoofer and I'd be north of another thousand dollars on top of the $340 I just spent. The car has low miles and is in very good shape, but it is 8 years old and I'm going to give it to my daughter in a few years. This is not something I want to drop huge money on. I might toss a Bazooka tube in the trunk, but that's about all I'd do. I am not a car stereo enthusiast. The only reason I replaced the head unit to begin with is that the CD player in the stock one died and I wanted BlueTooth.
