PA200.4 (4/3/2 channels)
High performance 4-channel mobile audio amplifier
Pure Performance.
The PA200.4 features a high-speed MOSFET switching power supply and high current bipolar output transistors for maximum voltage and high current to your speakers or subwoofers. A double layer fiberglass epoxy printed circuit board provides more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. This very efficient layout packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.
PA200.4 Features:
50 Watts x 4 (2 ohm) or 35 Watts x 4 (4 ohm) continuous power in 4 channel mode. 100 Watts x 2 (4 ohm) continuous dual bridge mono/2 channel mode.
80 x 4 (2 ohm) dynamic power.
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; as 2 subwoofers; or as 2 subs and 4-channels in passive-tri mode.
2 ohm stable 4-channel operation.
6-way Smart System Protection (SSP) circuits: Power and ground-reversal protection, thermal and short protection, current overdraw and low impedance protection circuits with auto-standby mode ensure safety, reliability and durability.
Anodized extruded brushed-aluminum cover and textured end caps for maximum heat dissipation.
Cast aluminum textured end caps for optimized heat dissipation and hiding of connectors. Solid aluminum logo and model panel back lit in cobalt blue.
Selectable 12 dB/octave high or low-pass crossover. Defeatable for full range (flat) operation.
Switchable 8 dB bass boost at 40Hz for extra bass thump.
Variable input gain optimizes match with different signal sources (250mv to 7.5V).
RCA outputs (front channels only)- for easy daisy chaining of other amplifiers.
Mounting hardware with rubber isolation grommets and extra fuse included.
Light bar/fan output-Connect an optional LED light bar or cooling fan for custom installations.
Multi-color status LED gives instant information on amplifier operation.

Rugged, stylish package (though I'll never see it...it's tucked away), plenty of adjustability for fine tuning. Plenty of power to drive the db651's.
Weaknesses:
It's big but all quality amps are.
Review:
Installed a PA200.4 with 4 Polk db651's in my boat. Head unit is a Clarion M309. What incredible sound! The speakers truly shine with this level of clean, clear power! I knew the stock system sounded bad but I didn't realize how bad the old amps were clipping.

Review:
I purchased this Polk Audio PA200.4 amplifier as part of an (initially) reasonably priced stereo upgrade for my 2006 Prius. However, when I received and installed the unit, I found that it introduced a noticeable (and extremely annoying) hiss into my system. This noise was present in all of my speakers (especially the tweeters) at any volume even when the amplifier wasn't connected to any inputs. Thinking that it was a problem with the particular unit that I received, I exchanged it for an identical unit and had the same issue. Eventually, I replaced this Polk amp with a nicer (and more expensive) JL Audio XD400/4 amplifier, which provided much cleaner and more powerful output in a smaller package. I understand that these amps are not directly comparable due to their price difference, but my experience has been to avoid the bottom-line amps from any manufacturer. I have been enjoying a more expensive Polk amp in my other car for the last few years, so I don't suggest that Polk amps all have this issue. However, the PA200.4 is certainly a dud in their product line. *Note: I should also mention that the coating on the rails of this Polk amp seems to corrode over time such that a white powdery finish forms at the surface. The first unit that I received had this problem worse than the second, but it was apparent in both. Although this "corrosion powder" looks like it will brush off, it is impossible to remove completely.
