Polk PA Series amps are only stable down to 2 Ohms.You MUST use 8 Ohm or higher subwoofers if you want to configure 3 or more subwoofers in parallel • How do I protect my amp? Protect your amp and your vehicle with a circuit breaker or in-line fuse placed no more than 12' (30cm) from your battery.
Impedance is defined as the amount of electrical resistance the subwoofer holds against an amplifier’s output.Things may get complicated when you wire dual voice coils and more than one subwoofer together.Parallel These two wiring diagrams are identical, because the SUB 1 output is paralleled to the SUB 2 output.If you don't want to crimp the wires together, the extra SUB 2 output is an excellent way to connect your subwoofers. Parallel DO NOT wire your subwoofers in a parallel configuration with 4 Ohm Single Voice Coil (SVC) Subwoofers if you have more than 2 subwoofers.Never run audio signal wires next to electrical power wires, because you will get loads of noise interference.
Run audio signal wires down one side of the car, and electrical power wires down the other. Run them under the carpeting or behind the plastic pieces.Resistance is a Static measurement (it does not change).Speakers do not have a resistance, as whilst the cone moves the effect of the magnets in the motor causes the resistance to change.Wire Gauge Speaker wires, as indicated in the Subwoofer Wiring Diagrams are used for wiring subwoofers. Some equipment, especially amps, have multiple OHMS ratings.If you have to drill through metal to run wires between compartments, use rubber grommets to pad the holes so the wires don't scrape the metal.
