A very noisy amplifier
By Scott C.
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.

By Jim
I agree with Scott's review of this amp. In fact, we had a very similar experience. I bought this amp directly from Polk and installed it. I'm not a pro car audio installer (meaning, I don't do it for a living), but I'm very experienced in audio installation. Immediately upon firing it up, there was a very audible hiss coming from my component tweeters. Thinking this was definitely not normal, I called Polk and spoke with a tech. He agreed that the amp was generating too much noise, and sent me a pre-paid shipping label to send it back. Nearly a MONTH later, I received a replacement. Hooked the amp up and still have the hiss. As a troubleshooting measure, I isolated all wires, disconnected the RCA cables, and even powered the amp from a jump box. That would be the ultimate test of whether my power/ground was bad. Even after doing all this, the amp still hissed badly. Apparently, it just is what it is. When I have some spare cash to burn, I'm going to upgrade.

Exact same problem as Scott and Jim. This is one noisy amp. The deck went out in my wife's Camaro and I thought while I'm replacing the radio I might as well do it right and upgrade the whole package. With a reasonable budget, I selected the Pioneer DEH-P7200HD receiver, a two pairs of Infinity Reference 6032si speakers, and about $100 of in-wall rated RCA cable and speaker wire, and nice expensive power cable and fuse from my local audio shop. So nothing too expensive, but not exactly cheaping out either, I just wanted a decent audio package that's not struggling to be heard with the top down on the car but recognizing that ultimate quality would be wasted on a loud noisy convertible.The first thing I did when I wired up the speakers was power them straight from the receiver to make sure everything was working. They sounded great! Nice and clear, no noise, seemed like it had plenty of juice so I was really excited to get the amp hooked up. Much to my dismay it was very, very noisy. I figured it must have been my installation, so I futzed around with the wiring and power cable and ground for a long time before I finally called tech support and told them my problem: I tested other external speakers and they hiss when there's nothing hooked up to the amp except an external battery (to eliminate my power and ground loop), no inputs to the RCA (to rule out the source as the noise), and just the short length of wire to attach the speaker. Boo Hiss!!They sent another unit out no problem to replace it, but the problem was no better or worse. After reading other reviews, that's just how it is apparently. I think I'll go back to using the receiver and use this as a paper weight until I get a real amp. Also had a Polk mid-range woofer for my home theater and that gave up after a couple years, and I don't even push it. My Ohm C2 speakers from the 70s are still working great after re-foaming the cones. QC at Polk is crap these days, very disappointing.
