The term "golden rule" refers to the optimal measurements for a box of a given volume. Making a box in a perfect cube shape, where all three dimensions are the same, is supposed to be bad for the creation of standing waves inside the box. IIRC, the ratios are 1:1.5:2.5, for example 12" X 18" X 30" for a 3.75cuft enclosure. Note that these are internal measurements, the thickness of the material must be allowed for when determining the cut lengths. Bottom line is make the 3 lengths different.....
Big 3 refers to upgrading the wiring under your hood to allow for better power supply to your amps. Specifically the battery to ground wire, and both leads off your alternator.
Yellow top is a common way to refer to a heavy duty dry cell battery. The name comes from the line of accessory batteries made by a company called
Optima, which feature plastic cases with very colourful tops.....
They are safe to install inside your vehicle's passenger compartment, since they have no liquid acid inside them to leak in case of an accident....
