Signal / Head Units
Receivers (“deck”, “source”, “radio”, “tape deck”, “CD Tuner”, or whatever you want to call them), are simply the component that generates the signal that you are trying to hear. The “format” is always changing, and although the Compact Disc is currently dominant, in the future we may (soon) [...]

What is “impedance” and “bridging”?

Amps are designed to “see” or “be hooked up to” a specific electrical resistive load called “impedance”. This impedance rating of speakers is measured in ohms, and will always be written on the speaker. And so, amps are rated as being able to produce a certain amount of power AT a [...]

“What the heck is Bi-amping?”
It’s very important to understand the need to “bi-amp” your vehicles’ sound system. That is, to make sure you have a power amp for your door speakers as well as one for your subwoofer. If you don’t, and you use the little, “BTL, IC chip” amp that is in your radio [...]
