The price you pay for a quality car audio system will vary depending on your budget, the components you want and the place where you purchase your audio system.
Receivers
The receiver, or head unit, is potentially the most important part of your sound system, as it affects the rest of your system.
A budget-friendly, high-quality receiver will cost around $120 (as of 2010), and a receiver your audio dealer may recommend might cost around $200. Receivers can exceed $1,000, however.
