BOSS Audio Systems CE102 2 Channel Car Amplifier - 100 Watts, Full Range, Class A/B, IC (Integrated Circuit)
Power - 50 Watts Max x 2 @4-Ohms
Class A/B Topology - Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal
Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
High & Low Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
Fixed Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set sound specifications for the bass frequency reproduction
Fixed High-Pass Crossover - Speakers reproduce sound based on high, low or mid-range frequencies. The High-Pass Crossover gears specifically towards “highs” including mid ranges and tweeters

Title: Amp
Review: Easy to install. Works pretty well for its size. Have them hooked up to 6x9s that sound great

Title: Not good
Review: I bought this as a subwoofer amp. It works but1) you turn it on and you’re greeted with a loud thumping - tried to fix this without resolving. Sent support an email - nothing.2) once the thumping stops, the souls quality was not very good.So all in all I took it out and it’s a paper weight. Too bad.

Title: Great little amp
Review: Got this to replace an amp in an RV entertainment system. From the photos it looked similar to my original one that died. Sure enough it was almost identical in size and connections making it easy to install. It was less wattage than the original, so I was worried about volume, but it has enough power to be hear over a very loud air conditioner and sounds nice and clean. Very happy so far.

Title: So far so good.
Review: I had a factory sub for a 2011 Honda CRV and the OEM amp is very small. This is the only amp I could find that would fit in the available slot on the sub. This with a slight mod worked well. First off after trying 2 of these amps the high inputs do not work at all, they should be deleted from this amp since they are useless. The RCA's do work well though. Just be aware you will need a Input converter if using a factory deck. The PAC input converter works very well. Another thing about this amp when the power goes on or off there is a thump sound from the sub. Its not too bad but it is noticable and it was supposed to have a soft on and off so another unexpected issue. I also noticed if you do not use the remote on/off orange cable the amp senses the inputs and turn the amp on and off. I wish the timeout for this was longer, the delay is only 1 second or something so the amp can go on/off alot if a song has no bass for a few seconds which is annoying. If the delay was 5 seconds it would be much better for some songs and between songs. Most the time it is fine though. If you use the remote wire it stays on with the car even if the radio is off, which is not too bad but wastes power and heats the amp all the time. I am still deciding which way to use it. I wish the auto on/off was a little better but works well enough. Nice amp so far even at 2 ohms, will see how long it lasts. It was getting pretty hot but has not overheated yet on the first day.Update: So the amp stopped working today. It has been installed for 45 days and was working ok until today. The "soft" power on and off always popped on power cycle since day one, so not very soft. The amp would sometimes turn off mid song, not sure why and then come back on again. Today it was just dead, no sound and cold but the power led was lit. All connections are good, it just doesn't want to work anymore. Nice. The return policy is garbage. It will cost me the same to buy a new amp vs getting Boss to repair mine. Amp is pretty much disposible. Beware.Update: So the problem was only the fuse. I added a fuse holder so I could swap them easier in the future. We are back in business. I have updated my rating.

Title: Loud enough for me
Review: Nice little amp for the price. Easy hookup. Enough to supply the watts you need to drive a mid or subwoofer for excellent sound but not enough to piss off your neighbor at the red light. I am using it to power a dual coil Pyle 6.5 mid woofer with the coils connected in parallel for 2 ohm resistance, and it delivers excellent mids and highs to complement the low end of 2 6x9's and 2 6.75's. Good for giving some extra boost in the tonal range of your choice.The three-way switch that allows you to select tonal range is a plus on this amp and gives it a versatility that other amps this size and price do not. For my purposes with the 6.5 Pyle, it sounds great in the high filter position and accents mostly mids.

Title: Wondering what's inside? A review for electronics geeks.
Review: For those who might be curious about what goes into these things, here are some answers.A single inductor is by the power supply input, along with the one discrete (bipolar) transistor that appears on the circuit board. It seems like a circuit intended to deal with voltage fluctuations, and maybe confer a degree of idiot-proofing, and I approve.Most of the other parts in evidence are the minimum needed to do about a third of what this amp's spec sheet claims. Aside from some small value mylars and a couple of ceramics, all of the capacitors are Taiwanese, aluminum electrolytics. At least 3/4 of the resistors appear to be carbon-based. Buffering is provided by a UTC4558 dual op amp chip. Amplification is provided by a 4-channel amp-on-a-chip, the $2.50 STA540SAN. At 12 volts, this chip is good for 4 channels x 9 watts @2 ohms, but can be bridged to provide 2 x 18 watts @4 ohms instead. That's exactly what we have here.If I were making this amp, I'd spend an extra couple of dollars to use higher quality resistors and capacitors, because they'd last longer and sound better. On the other hand, it's not much over $20, and I couldn't build one of them for that. Parts are a lot more expensive when you buy a few, than when you buy thousands at a time, and I'd probably get gouged for >$10 for the box alone.Yes, it's cheaply made, and inflates its wattage from 36 to 100. My "90 watt" Pyle amp produces 6-8 watts per stereo channel. Inflation of car audio specs is SO nearly universal, that doing 36% of what's claimed is, relatively speaking, not bad at all. If you use it in a car and are maintaining something close to the 13.8v maximum that most alternators can produce, you might hit 25 watts a channel. If you're driving a couple of subs with it, that will give you sound levels about 17 dB over the efficiency of your speakers, so if you bought efficient speakers, let's say 96 db/watt, you'd get about 113 dB. That's loud enough to damage your hearing pretty quickly, and is more than most buyers would ever want. Continuous exposure to over 90 dB is deemed harmful for hearing, and a pair of 98 dB/w speakers could do that on about a twentieth of a watt per channel. (Hey, if you bought 82 dB/watt speakers and need 7 watts to get to 90 dB, don't blame me... )One thing I found in the data sheet for the STA540SAN, was mention of the idea that manufacturers could save themselves the cost of a part, plus circuit board real estate and insertion costs, by using a single DC-blocking capacitor for both of the stereo channels. They also mention, in vague terms, that it will harm stereo separation to do that. While I did see some pairs of caps on the board, none of them were very near the output stage, so I suspect that Boss may have done that with these amps. If you're using them for subs, you'll never know or care, but if you're using one for higher frequencies and get crosstalk, that might be why. It's common in budget amps. In the rare event that an output capacitor fails by becoming a short circuit, it can allow the DC power supply to flow directly through both channels of your speakers, which is likely to fry many drivers almost instantly. I'd have felt better if just that one cap was a solid type, rather than an aluminum oxide paste cheapie.But hey, did I tell you it was only about $20?

Title: Generates a lot of heat but no sound
Review: Wasted like an hour wiring up this POS and it doesn't work at all. It turns on and gets hot as hell, but regardless of how I adjust it, my bass shaker barely makes a rumble

Review: I purchased this unit because I trusted the BOSS brand and I’ve had good luck with there other products however this amp is nearly unusable, when turned above about 25 percent volume it starts creating a popping sound through the speakers too loud to ignore, when under 25 percent it seems to be fairly stable though not very good sound quality. Looking through the other comments, the popping sound seems to be a common issue.
