Setting Up Your Car Audio

• How do I wire my amp to a sub?

Wiring your subwoofers to your amplifier can be tricky tricy, that's why we created these wiring diagrams. You don't want to blow up your subwoofers OR your amp. (In fact, we recommend that you skip right over to your local Authorized Polk Audio Dealer and get a pro to do your install. We feel we should say that, so you're warned and all.) If you blipped right over that sentence in the parens, we've gone ahead and made it easy for you to find the proper wiring method with these diagrams.
Below are wiring diagrams for 1, 2, 3, and 4 subwoofer configurations for both single voice coil subwoofers (SVC) and dual voice coil subwoofers (DVC).

 


1 SVC Driver

The simplest way to hook up a subwoofer. The total impedance of this system is 4 Ohms.


1 DVC Driver

Parallel

When using a 4 Ohm Dual Voice Coil (DVC) subwoofer, the total impedance of this system is 2 Ohms.


1 DVC Driver

Series

When using a 4 Ohm Dual Voice Coil (DVC) subwoofer, the total impedance of this system is 8 Ohms.


2 SVC Driver

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. The total impedance of these systems is 2 Ohms.


2 DVC Driver

Parallel/Parallel

DO NOT wire 2 DVC drivers in Parallel / Parallel configuration. Polk PA Series amps are only stable down to 2 Ohms. The total impedance of this system is 1 Ohms.


2 DVC Driver

Series/Parallel

When using a 4 Ohm Dual Voice Coil (DVC) subwoofer, the total impedance of this system is 4 Ohms.


3 DVC Driver

Series/Parallel

When using a 4 Ohm Dual Voice Coil (DVC) subwoofer, the total impedance of this system is 2.67 Ohms.


3 & 4 SVC Driver

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. 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

4 DVC Driver

Series/Parallel

When using a 4 Ohm Dual Voice Coil (DVC) subwoofer, the total impedance of this system is 2 Ohms.


4 SVC Driver

Series/Parallel

Total impedance of this system is 4 Ohms.

• How do I protect my amp?

Just be strong. Protect your amp and your vehicle with a circuit breaker or in-line fuse placed no more than 12' (30cm) from your battery. This circuit breaker or fuse should be no greater than the fuse(s) of your amplifier for optimal protection. For example, your Polk PA Series amplifier has two 25A fuses. Your vehicle protection fuse should be rated at 50A. See your authorized Polk AutoSound Dealer for professional advice on fuses and circuit breakers.

ALWAYS DISCONNECT YOUR VEHICLE'S BATTERY GROUND BEFORE WORKING WITH YOUR VEHICLE'S ELECTRICAL SYSTEM.

• How do I safely route my wires from the front of my car to the back?

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. Never run wires outside the car or under the car. Run them under the carpeting or behind the plastic pieces. 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.

• Where can I safely install my amp for best performance?

You can install your amps pretty much anywhere you can:
  • get a good short ground connection
  • get a secure, screwed down location so the amp does not move around and most important
  • anywhere the amp will have enough breathing space to be able to properly vent itself so it doesn't overheat. Under your car seat is a good place.
Carbon Series Amps have a low profile so they fit easily down there and it's a pretty easy place to connect wires and make adjustments (although you do have to remove your seat to do the initial installation).

• What are the LED's on my amp for?

Power
This indicates that the amplifier is receiving the proper remote and power supply voltage and the unit is on. When the amp is on, a blue colored LED illuminates.
Thermal Protection
The amplifier has reached an unsafe operating temperature and has turn off to protect the output transistors from being damaged.
Short Protection
The amplifier is sensing a shorted speaker or speaker wire.
