Guides and comparisons
- Car Amplifier Buying Guide: Picking the Right Amp for Your CarThe right amp depends on three things: what radio you have, what you want to power, and how much room you can give up. Tell us those and we can usually narrow it to two or three amps in a few minutes. Here is how we walk people through it at the counter.
- 4-Channel Car Amplifiers Compared: Kicker, Rockford Fosgate, Pioneer, JBL and HertzA 4-channel amp powers four speakers, usually the front and rear doors, or a front component set plus a sub when you bridge the rear pair. More clean power lets speakers play louder without the distortion a radio's built-in amp runs into.
