[. . . ] Your sound system is far more than just a combination of dials, wires and speakers. It is an integral part of the audio chain and should be treated with special care and attention to detail. [. . . ] When speakers are connected in parallel, their combined impedance decreases. For speakers wired in series the opposite is true, their combined impedance increases. Thus, when speakers are wired in series, higher impedance speakers in the series draw more power from the amplifier than do speakers in the series with lower impedances. Higher impedance speakers will draw less power from the amplifier than lower impedance speakers will draw. At Fender ®, we recommend connecting multiple speakers in parallel for several reasons. Second, because in a series connection one speaker affects the output of the other speakers, unpredictable frequency response is a concern. Third, most speaker cabinets are already wired for parallel connections making parallel connections the most common wiring method. Below are two charts demonstrating how to calculate both parallel and series impedance. PARALLEL IMPEDANCE Zp = Cabinet B Impedance 16* 5. 3* 8 4 8 5. 3 1 1 1 1 + Z 1 Z 2 . . . Z n + + - Keep in mind, power and audio signal cables are the most common sources of sound system failure. Well made and carefully maintained cables are essential to the reliability of the entire sound system. If long speaker cables are required, it is important to ensure the cable`s gauge is sufficient to transfer all of the available amplifier power to the speakers rather than absorbing the power itself. As a rule of thumb, larger wires are better as they conduct more power to the speakers (larger wire has smaller gauge numbers). [. . . ] To clean the Tolex covering, use a sponge and a light soapy water solution to wipe away any smudges or dirt. For stubborn stains, a slightly more concentrated soapy solution may be used.
