Review: Por ese precio es muy buena compra! - 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: 良き - 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 Ohm, 550 Max x 1 @ 4 Ohm
- Class A/B Topology - Class "A" amplifiers have a huge amount of current flowing through its output transistors without audio signal. Class "B" amplifiers have no current flowing through its outputs without audio signal
- Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. Control the output voltage and current accurately by removing the loss of detection of the output current and eliminating all secondary feedback circuits
- Low and High Level Inputs - A low level input (RCA) is measured in voltages. A high level input (+/- wire) is measured in wattages. Both basically carry the signal from the receiver to the amplifier to the speakers
- Variable Low Pass Crossover - Subwoofers reproduce sound based on a range of different low-range frequencies. You can set the exact sound specifications for bass frequency reproduction. Switchable Bass Boost - Bass Boost lets you adjust the bass within the boost range just the way you like. Variable input gain control - Gain control is not for volume adjustment. Simply adjust the amount of signal coming from the receiver and switch to the amplifier.
