Amplifier Wiring Kits
Get all the cables, wires, and hardware you need to install your new car amplifier with one of these power amp kits. Amplifier wiring kits come with your basic power and ground cables, as well as other necessary wires. Select complete amplifier kits will include speaker wire, RCA interconnect cables, and more! Make sure to get the kit that is best designed for your car audio system.
Capacitors
Car audio capacitors are a great addition to any aftermarket audio system that is in need of a little extra power. Capacitors store a temporary electrical charge that can be released during periods of extra power strain. If a vehicle has dimming headlights when music is played, a capacitor could solve that problem.
Sound Processors
For those who want the most out their car audio system, a quality sound processor is a must. After some slight adjustments, your systems will sound like it has been professionally tuned and optimized. Tune your system to perfection with these crossovers, equalizers, and bass drivers.

4-Channel Amplifiers Information

A 4-channel amplifier is the best way to power a complete set of new car speakers. These amplifiers are designed to power four door speakers, although the right & left channels can usually be bridged to offer a wide range of wiring options. Commonly, the rear channels will be bridged to power a small subwoofer while the front channels are used for the front speakers. Some audiophile installations use these amplifiers to bi-amp a pair of component speakers – in these setups, each tweeter and midwoofer is powered from their own channel. Four channel amplifiers mostly utilize class A/B circuitry for the best possible sound quality, but the last few years have seen a huge rise in the popularity of full-range class D amps. These amplifiers are prized for their compact chassis, and advances in technology have made them sound almost indistinguishable from their A/B counterparts. 4-Channel amplifiers also frequently feature preamp outputs or signal pass-thru, allowing you to provide signal to a subwoofer amp without running another RCA cable to your head unit.
