Car Audio
Car Subwoofers Information:

Subwoofers are dedicated to reproducing low audio frequencies and provide depth to the overall sound of your music. We carry a variety of subwoofers in all shapes and sizes. When choosing a car audio subwoofer, keep in mind the amount of space in your vehicle and your preferred style of music.


The RMS power handling rating refers to the amount of power a sub can handle on a continuous basis. We recommend giving your sub 75% - 90% of its recommended RMS rating to help prevent over-powering or "blowing" your sub. You should select a car stereo subwoofer based on the amount of power output generated by your amplifier, the sub's impedance and the voice coil specifications. Subwoofer impedance can be rated at a 2 ohm, 4 ohm, or an 8 ohm load. The number of voice coils allow for different wiring configurations. The type of voice coil setups includes single, dual, or quad voice coil.


An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the sensitivity number, the greater efficiency. A higher sensitivity rating also indicates that the speaker will play louder, given a set amount of input power. This is because an efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter away from the speaker. Some are measured with 2.83 volts of input rather than 1 watt.


Car Speakers Information:

Upgrading your car speakers is the best and most affordable way to improve your sound system. An after-market set of speakers is better able to handle a wider range of frequencies, giving the lower notes greater depth and making the higher notes sound more defined. After-market car speakers are built with materials that are durable and temperature resistant. For example, most auto speakers include a rubber or foam surround for enhanced durability. Our wide selection includes various sizes of full-range 2-way, 3-way and component speaker systems.


Our full-range car speakers are available in many shapes and sizes. Most feature a woofer and tweeter molded into the speaker. Some also have midrange drivers. In contrast, component systems feature separate woofers and tweeters. This allows you to mount the tweeters in an optimal location for generating a more realistic sound. They also have midranges and external crossovers, which send separate frequencies to the woofer and the tweeter for a more efficient reproduction.


Car Stereo Amplifier Information:

A car audio amplifier acts as the power source to your sound system. Technically, the amplifier modulates power generated from the car battery. An amp specified to your speaker's inputs will fully orchestrate your sound system with low bass beats and high frequency sounds.


Vehicle amplifiers can be used with any stereo, from factory stereos to after-market head units. For after-market stereos you connect the amp through the preamp inputs in the head unit. Factory stereos work well with amps that have speaker level inputs because it allows you to work with your vehicle's current speaker wiring scheme without requiring any additional connection pieces. In terms of configuration, an amplifier usually requires wiring kits, which are designed to connect the stereo to the amp so as to enable the amplifier to receive a signal. In addition, an amp installation requires speaker wire so that you can connect it to the subwoofers and speakers.


An amplifier acts as the centerpiece to any state of the art sound system. Any audio system that features subwoofers must also have at least one amp to provide enough power for the subwoofers to operate as designed. A head unit can only provide limited power, whereas the superior power of an amp enables your subwoofers and speakers to reach their full potential.


2-channel and 4-channel amps are also used to power component speaker systems, while 4- 5- and 6-channel amplifiers are used for systems with a combination of full-range speakers and subwoofers. For example, you could use a 4-channel amplifier to power a pair of speakers through two channels and bridge the remaining two for powering a single subwoofer.
