PA AmplifiersPA mobile audio amplifier are high speed MOSFET amplifiers that will provide all the high- performance juice you need to ensure your car speakers perform to their full potential.PA amplifiers represent a new generation of compact, super efficient power sources created for the budget-minded enthusiast who desires uncompromising performance from their car’s sound system. Yet they’re powerful enough and loaded with features that the serious audiophile can do battle with at a competition. The amps’ sleek designs work in any kind of install, from retro American classics to high performance European machines. Efficient circuit board design helps create a more compact amplifier. Double layer printed circuit boards provide more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. PA amps are very compact, and their efficient layout houses more circuitry, with tighter component tolerances, onto a smaller circuit board, helping create a smaller overall footprint.
PA amps come with plenty of protection. We know how hard you like to play, so every PA Series amp comes with Thermal, DC offset, reverse DC voltage and short circuit protection.
Anodized extruded- aluminum housings and stainless steel hardware.
PA Series amps are built tough with anodized, extruded aluminum covers and rugged end caps. Cooling fins along the length of each amplifier’s main housing ensure ample heat dissipation. The end caps also protect connectors, while stainless steel hardware is used throughout each D Series amp to provide years of corrosion free performance.
PA Series amps are all about performance pure and simple.
An amplifier’s real story is told in its specifications. So choose your favorite amp, and check out its specs. You’ll find gobs of performance and all the controls you need to tailor your system to your vehicle’s listening environment.

Power and style that amplifies
The PA660.4 is a four- channel class A/B amplifier with built-in fully variable low-pass crossover. Equipped with remote gain, the PA660.4 is capable of two- channel operation with a maximum power of 600 Watts when both the front and rear bridged channels are driven into 4 ohms speaker loads.

PA660.4 Features:
• 75 Watts x 4 continuous, 85 x 4 dynamic power (2 ohm load), 4 channel mode.
• 150 Watts x 2 (4 ohm) continuous power, 2 channel mode.
• CEA- 2006 compliant specifications for true, accurate power ratings.
• 4-channel, dual bridge-mono (2-channel), or dual simultaneous stereo/mono operation provide a variety of configurations and setups: 4-channel for front and rear speakers; 2 speakers and a sub; 2 subwoofers.
• 2 ohm stable 4-channel operation.
• High- speed MOSFET switching power supply and high current bipolar output transistors pump maximum voltage and high current to your speakers or subwoofers.
• Double layer fiberglass epoxy printed circuit boards for more rigidity, less shrinkage and a smaller overall amp footprint.
• 6-way Smart System Protection (SSP) circuits.
• Variable bass boost (0dB, +8dB) for extra bass thump.
• Variable input gain optimizes match with different signal sources (250mv to 8V).
• Mounting hardware with rubber isolation grommets and extra fuses included.
• Multi- color status LED gives instant information on amplifier operation.
• Color: chestnut brown, paintable.
• Durable, high performance fabric dome tweeters deliver clear and detailed high frequency response and excellent imaging.
• Capacitive Coupling Technology (CCT), an advanced signal-blocking technology that overcomes the usual limitations of small- enclosure loudspeakers (slim dynamics and no low frequency response), delivers extended dynamic range and enhancing deep bass response for clear, detailed musicality with little or no coloration.
• Glass-filled ABS enclosure is super-dense and acoustically inert, ensuring an extremely clean and low coloration midrange response.
• Paintable white finish blends into any decor.
• 5-way gold-plated binding posts, for the best connections, are easily accessible no matter how you mount your speakers.
