spending money isn't as important as spending time doing the installation well. i have hundreds of hours in my car - well over 400 hours by now. while the cost of my equipment is under $1500 because everything was bought used (retail is over $4k), i've tried dozens of configurations with many different products to nail down what i want. and i still have other speakers to play with, modifications to make, etc. it sounds great, and most people would be happy as-is, but i also experiment so i can answer questions and generally increase my knowledge. just last night i spent 2 hours building new tweeter spheres.
