    If you’re a hard core audiophile, you’ve come to the right place. The equipment here is for the high fidelity enthusiast who can discern subtle differences in sound quality; those with tin ears can move along. For the music lover who wants more than just a lot of volume and bass from an amp and a subwoofer, we’ve gathered the instruments that allow you to fine tune your car stereo sound including equalizers, processors, crossovers, and bass maximizers.

    Let’s start at the stereo receiver. Most receivers don’t output the voltage that the amplifier can handle, and more is lost through the wiring. We offer line drivers that will boost the signal from the receiver to the amplifier, so the amp can deliver the performance it’s capable of without noise. We also have bass restoration processors that boost frequencies suppressed by factory receivers and in compressed audio files.

    Inside an automobile is a tough place to create quality sound. There is an abundance of different surfaces, some of which absorb sound like seats and carpet, and others that reflect it, like glass and plastic. Plus there is the ever present road noise. A standard receiver will let you adjust little more than bass and treble, but an equalizer will allow you to tune the sound to suit your taste and help overcome the shape of the cabin or less than ideal speaker locations. With an equalizer, you can adjust individual frequency response, to add more boom to the low bass, add clarity to vocals, and reduce irritating brash tones.

    Speakers are designed to optimally handle different frequencies, with high frequencies for tweeters and low frequencies for woofers. Crossovers direct these frequencies to the right speaker, so tweeters don’t have to try to put out low notes and subwoofers high notes. Full range speakers filter out frequencies, but component speaker systems have passive crossovers connected between the amplifier and speakers. Active crossovers are wired between the receiver and amplifier, and allow you to adjust the signal level to individual channels, so the amp only boosts the right frequencies.

    The capabilities of signal processors can vary, but the most complete ones have equalizer and crossover functionality that enables you to completely control the sound in your vehicle. They can usually be used with both factory and aftermarket stereo systems, but they really shine when used for factory integration because they remove the designed in factory sound limitations. For example, if you’re using aftermarket speakers with a factory receiver, a signal processor will let you get the most from them by overriding the factory settings designed to limit bass output to protect low quality factory speakers.

    Good Product
    When looking for crossovers to purchase and on the cheap these are great. Just because they are inexpensive does not hamper their quality.
