I'm going to San Diego in a few weeks and want to buy some car audio equipment, nothing too exagerated, just a pair of 5x7" speakers for doors, a 8" Subwoofer and may be an Stereo. I want to install it to a Ranger 1994. So I only want is a high fidelity, not a high power audio. Where can I get accessible prices and good brands?

Thank you, fellas.
