Review: Aunque yo lo instale bastante rústico, la potencia y eficiencia del amplificador es buena, ya lleva 3 meses trabajando casi todos los días (alimentando un Kicker10” Cwcd104 Doble Bobina 500w y está en óptimas condiciones aunque lo traigo todo cochino porque lo instale en mi camioneta de trabajo 👍
Review: カロのアンプを物色中にたまたまアウトレットで安くなっていたので購入。 アルパインのウーファーをキチンと鳴らせている。 今の所何も問題はないです。

## Features

- Power - 1100 Max x 1 @ 2 Ohms, 550 Max x 1 @ 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
- Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
- Low & High 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
- Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction.Switchable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.Variable Input n Control - The n control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier.

Yes it’s one star. It would’ve been (I hope) 3-5 stars but it’s too bad the screw and screw holes complete ruin your set up, unless you won the lottery or became president in 2025 you would connect the amp and sub first try without any wiring/ securing problems. The +/- holes are not threaded and you need to perfectly screw them on the correct angle on your first attempt and you better hope your subs are wired properly cause there’s no turning back on this terribly designed amp. I would try to screw the wires down, then I think it’s good, give it a little tug and the wire comes out. Wish I could comment on the lack of power as other people stated but noooooo lol can’t even hook it up. Company’s sell trash, yet the consumer is punished and need to pay to get rid of the trash. Now I’m going to ruin the environment to have this trash transported back to BOSS lol. What a joke. If it’s trash then take it off the internet. People say this amp is good when you’re on a budget yet they most likely need to return it or buy another one costing more. hahaha what a joke world we live in.
