Product Description
AudioSource Amp 100 is a power amplifier that is versatile enough to be used to drive speakers with different impedance ratings in stereo mode. Ot also allows bridging the 2 separate internal amp circuits for higher power sound to one channel. Though designed for home use, the bridge-application makes this suitable for use in bars and restaurants, where stereo channeling might not be considered, but high quality output is definitely an issue.

Amazon.com Product Description
A favorite of audiophiles everywhere, the AudioSource Amp 100 two-channel power amplifier is built to deliver powerful music, pure and simple, with few extra controls to get in the way. Listeners can use the Amp 100 as an independent stereo amp (50 watts x 2 into 8 ohms) when used with a preamp, as a second zone amplifier in multi-room applications, or as a rear-channel amplifier in a 6.1- and 7.1-channel system. Combine the Amp 100 with an additional monoblock amp (the Amp 100 delivers 150 watts RMS of bridged power) and a preamp and listeners can independently drive two front left/right speakers or two rear speakers, further clarifying each channel to create dynamic, high-end sound. To connect additional components to the amp, use the included stereo inputs with automatic priority override (for connecting to a source such as a receiver, CD player, or preamplifier) or the auxiliary output for creating a multi-amp setup.
The amp boasts a precise frequency response of 20 Hz to 20 kHz and total harmonic distortion of 0.02 percent. Additional features include A, B, or A+B speaker selector switches, front-panel mounted volume and balance knobs, and five-way binding posts that work with both bare wire and banana plugs. Plus, at 16.5 by 2.9 by 9.25 inches (W x H x D), the device should fit comfortably in most rack mount or home entertainment setups. All AudioSource amps are backed by a two-year warranty on parts and labor.

Very reliable, good quality product.......2007-12-26
The Amp 100 provides good amplification and is extremely simple to operate, it took me two minutes to plug everything in and get started. I would have liked bass and treble control knobs but you can regulate that from the source anyway.
NOTE: to all those complaining about the auto-off feature that turns the amplifier off whenever no signal is detected, it can be turned off via the switch in the back. Idiots.
functional amplifier.......2007-12-22
Simple yet functional. No unneeded bells and whistles. Great to connect on one end to a USB-DAC which is in turn plugged into your Mac or PC, and on the other end to external large speakers. The sound produced meets and beats any high-end sound card output.
very impressed.......2007-12-05
Based on the reviews I read here on Amazon, I felt confident that this was the no-frills, inexpensive amplifier I wanted to power my speakers. We use an older Mac Powerbook for internet radio and all music that we want to access is on my external hard drive...this amp was easy to connect right out of the box and sounds like a million bucks. It has lots of power which easily fills up our fairly small home.
Kudos to Amazon...I ordered it last Sunday, went for the free shipping, and true to the confirmation email I received, it showed up 2 days later. For $90, my prayers have been very answered...i got an affordable amplifier that has no frills to fuss with and does the job.
Audio is always cutting out.......2007-12-02
This would be a fine product except for the fact that it has this mechanism to cut sound output when the sound level falls below a certain threshold. There is a switch to turn off this "feature" but it doesn't work. The result is that the sound always cuts off when your music volume gets low. It's extremely irritating when you're trying to listen to the soft parts of songs or when you don't want to blast the output. I want control my volume via remote, buy I have to manually adjust the volume knob instead and when I don't feel like cajoling the amp, I just let the music periodically cut out but get irritated every time it does. I would not recommend this product as a result of this problem.
A great amp to use with iTunes and power backyard speakers.......2007-11-29
I used this to power a pair of outdoor Bose speakers on my back deck and it works well. Runs cool; I have the AudioSource Amp installed in a closed kitchen cabinet with no heat problems.
My music source is an Apple AirPort Express with Air Tunes (M9470LL/A) connected to the amp through an headphone jack splitter. All my music is stored on an XP PC in iTunes and streamed wirelessly to the Air Tunes box. I have the AirPort Express sound jack connected to two amplifier inputs; 1-a cheap $16 powered PC speaker set (has subwoofer) for listening in the kitchen (sounds great!), and 2 - this AudioSource amplifier. Music quality is good through the AudioSource Amp. I wish it had a bass boost but I think that is a problem with my Bose speakers.
A great value.

Product Description
High efficiency, Low-Pass Filter for Subwoofer, Line-Out Jacks for Expansion, Intelligent"" Bass Servo Circuit, Versatile Bridgeable Amp.
Amazon.com Product Description
Make a powerful audio statement with the 1,000-watt CY-PA4003U vehicle amplifier. The four-channel amp (250 watts x 4) is valued for its high efficiency--an essential trait when it comes to driving powerful car speakers over long periods. To maintain this efficiency, the CY-PA4003U employs full MOSFET circuitry with a low internal impedance and minimal heat generation. The circuitry both reduces the load on the car's battery and helps preserve the transparency and crispness of the original audio signal to ensure a faithful reproduction through the connected speakers.
The amplifier also offers an "intelligent" bass servo circuit that adjusts to the limitations of traditional woofers. Compared to most midrange and tweeter drivers, woofers have a larger mass, heavier voice coils, and more inductance, thus they need more current to start moving. The increased current often causes the bass to lag behind the mid and high frequencies, resulting in unnatural tonal coloration. Furthermore, because of their longer throws, the woofers' voice coils have a tendency to deviate from pistonic motion, resulting in nonlinear dynamic distortion. The CY-PA4003's bass servo circuitry overcomes these shortcomings by feeding high current to the woofers at the moment of startup and instantaneously detecting and correcting the voice coil movements. This maintains the pistonic motion and linearity while helping the bass synch up with the rest of the frequency spectrum to produce a more authentic overall sound.
Though the CY-PA4003 is designed to drive four speakers, listeners can also bridge it for three-channel (two speakers and a subwoofer) or two-channel output (stereo), depending on their needs. To make the sub option more optimal, the amp also includes a low-pass filter that adjusts the cutoff frequency continuously from 50 Hz to 250 Hz. As a result, it's easy to upgrade to a subwoofer system that matches your speakers' low-end frequency limits.
Finally, the amp includes line-out jacks for easy expansion. The jacks let you connect multiple amplifiers--a must for power-obsessed listeners--while still keeping the wiring neat and tidy. Other features include gold-plated speaker terminals, a thermal shutdown protection circuit, and blue illumination. The amp measures 13.12 by 2.44 by 11 inches (W x H x D).

Good Amp. Excellent value........2007-03-27
I bought this amp from Amazon because of the price and free shipping and no tax. For the money, this is a solid amp. I recommend this amp to anyone who looks for a economic way to upgrade car audio system.
I used the 3-channel setup. 2 channel for front speakers and 1 bridged channel for subwoofer. My previous amp was a built-in amp with Eclipse Head Unit, rated at 15W RMS, needless to say, at 15W the sound quality is terrible . Now look at this unit's 64W RMS, the difference is night and day. Mids and Highs are good, not excellent, but I am not asking for that much at this price. I am satisfied.
The bridged subwoofer sounds a little weak, however. I already adjusted the gain and bass boost but still I am not getting what I want.
The amp looks OK. Its nothing to write home about. You are not going to show your friends this amp because of its looks.
Build quality is pretty solid (made in china). The "gold-plated" speaker connectors look cheap.
User manual is very good. Installation instructions are easy to follow.
Overall I give it 4 stars.

Amplificador defectuoso.......2007-05-13
Soy de Caracas, Venezuela. El amplificador me llego perfectamente embalado me dirigi a un sitio que instalan estos equipos y cuando me lo instalaron tiene un canal de los pasivos que esta fallando, aveces suena y otras veces no. No procedo a garantia debido a que estoy fuera de U.S. y me sale muy caro el envio.

Amp.......2007-05-07
Good amp. Use it for my front and rear door speakers and they sound good.
amp.......2006-04-07
I should have read this feedback before I made my purchase. If i am not happy with this product this will be my last purchase from amazon.com or if I dont get my 20ft cable. Customer service here is terrible. I thought ebay was bad but atleast someone from ebay contacted me.
Mixed Feelings.......2005-12-11
Replaced an Alpine 18wx4 amp with the Power Acoustik OV4-600 to push my Kenwood 6x9's and Kenwood 6.5's. While I like the features and like the price, there is just something missing. I really expected a boost to my speaker performance because I knew I was underpowered. Well, I got a little more volume but I think the bass output is actually weaker. I think this would be a decent amp to push your midrange and tweeters but I seriously question the 70x4rms @ 4ohms power output that the manufacturer boasts. It's really a good value for the money but I would, at the very least, move up to the 800 if I had it to do again (if not consider a different brand).
Also, I never received the 20ft cable that Amazon advertises with this amp and their customer service has failed to resond to my inquiry. Caveat emptor.
