car/alternator combination that meets necessary requirements.
It is also very important that a power amplifier is not used without an appropriate speaker
load on each channel. The design of each amplifier is different, and so some amplifiers will
tolerate running with open circuit channels, wheras some absolutely will not. It is easy to
quickly damage an amplifier if channels are left open. Always make sure minimum
impedance requirements are met. The most common examples we see are four channel
units where one half of the amp is used to run a pair of speakers or a subwoofer (even
worse) and the other side is left undriven. This will almost certainly destroy components on
circuit board resulting in smoke/fire/certain failure of the amplifier. We have also seen
similar incidents where mono amps have their load removed (subwoofer taken out of the
boot on a quick release) but where the remote cable still powered up meaning the amp is
receiving a full signal! This is also likely to fill your car with expensive smoke. It goes
without saying, but we will say it anyway, that this is yet another warranty void situation.
(And like all the other ones, it is easily avoidable!)
