Key Specs
- Continuous Watts x Channel @ Ohms: 75 x 4
- Maximum Watts x Channel @ Ohms: 75W x 4 x 2 ohms (This is the maximum load the speaker, subwoofer or amp can drive.)
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 4
- Bass Boost: Selectable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
- Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
- Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

Rated 4 out of 5 stars
Outstanding clarity and power
Used this amp as an upgrade to an older one I had so I could get a little more volume in my 2009 F150 regular cab. I was happy with what I had before, but this amp has no issue keeping up with my demand. I'm impressed with the low temperature it seems to operate compared to what I had before. This is wired from my factory stereo using the high-level inputs and driving a pair of 2Ω Infinity Kappa component speakers in the front, and a sealed 12" Rockford Fosgate P3SD212 at 4Ω bridged on the rear channels. Using this amp as a 3-channel setup in this case. This amp is outstanding, especially for the money. The only reason I gave it four stars is the bass boost is not adjustable. It's either of, or at +12dB which is pretty extreme. The only reason I use the bass boost is to compensate for the factory stereo's lack of adjustments other than bass and treble. If you're using a quality aftermarket head unit with a dedicated subwoofer output, this is a non-issue since bass boost should be set on the headunit, not the amp. I set the gains with a multi-meter with the stereo set to neutral, LPF and HPF disabled, and using 0dB 60hz and 100hz test tones. They front required very little gain to be set to achieve its rated output. Mine was tested at 89 watts at 2Ω according to the test card included with my unit, so I set the front channels to push at 80-85 to ensure peak performance and reliability. But once I listened for a bit, I wanted to compare with the bass boost enabled. With bass boost enabled and the gain all the way down on the rear channels, I'm pushing 190 watts bridged at 4Ω. But after momentarily setting the bass and treble on my stereo, it sounds stunning with absolutely no clipping or distortion. It is absolutely perfect for a truck as the output is incredible, the footprint is small, and power draw low. Absolutely no dimming lights with the factory 135A alternator and a healthy battery no matter how hard it's pumping rock, metal, dubstep, and pretty much anything other than country or tween music, which will never be heard by me! Last thing to note was this amp was limited by the factory speaker wires on the front initially. They sounded fine, but the factory wire couldn't keep up at high output. So after fishing some fresh 14 gauge speaker wires directly from the amp to the speakers, the performance is amazing. I liked it so much, I just bought another tonight and will use it to drive a pair of 8" subs that will be going in a 2011 Taurus. I have an aftermarket head unit in there, so controlling the subs will be even easier.

Great amplifier for the money.
Bought this amplifier to help push some door speaker I also purchased and I was pleasantly suprised with the sound quality. This amp was easy to install and set up. Makes my Avalanche sound like a concert hall.
