The Polk Audio PA660.4 is a conventional type of car amplifier that features an incredibly small chassis, yet with a sound output that is simply amazing. The sheer size of this amplifier makes it easy to install practically anywhere within your ride. Given a great finish in black anodized brushed aluminum heat sink, the amplifier boasts great mass given its puny size. The messy wiring and connections are well camouflaged, thanks to the integrated molded end caps. With the power and speaker connections located on one end, and a pair of 25A ATC type fuses at the other, the Polk Audio PA660.4 comes with inputs controls and adjustments located conveniently.
The built in 12 decibel octave crossovers convey the all-pass and high pass filters to the front channels, while the rear channels get the filters for the low or high pass, including all pass setting. With the crossover frequency range set at between 50 Hz to 500 Hz for all the configurations, the bass boost that comes for the front and rear channels is independently adjustable. Thanks to the 2/4 channel switch, you have the liberty of driving all four channels with a single pair of RCAs whenever required. The conventional class AB design is based on high current MOSFET technology and also features a couple of complementary bi-polar transistors for each channel inside the amplifier. You can also have the rear channels bridged to a subwoofer and have the crossovers adjusted to suit your loudspeakers, and enjoy the divine music emanating as you drive your ride around town.

Car amplifier installation
We show you the complete process of installing a Pioneer Double DIN car stereo in a Chevy truck. The in-depth video shows the installation of the interface, and steering wheel control.
Amplifier Installation basics
Let's start with the basics of adding or installing a car amplifier. First you will need to plan your installation and power wiring, this usually is the most difficult part of the installation for most.
How to choose the proper wire size explained
What size power wire do I need for my amplifier? Well, that depends on the length of the wire and the power consumption of the amplifier. We walk you through how to choose the right gauge wire and wire material depending on your amplifier installation requirements.
How to wire speakers and subwoofers to your new amplifier
In our third video we demonstrate the various ways you can wire speakers and amplifiers to all types of amplifiers. There different ways to do this depending on the type of amplifier you choose to purchase.
What is gain? How do I set it properly?
In our fourth video we demonstrate how to set the gains on your amplifier to prevent damage to your speakers, subwoofers and even possibly your new amplifier. Using a portable oscilloscope we show you how to set your gains.
