Product Overview

The SoundQubed Q4-150 is the most versatile amplifier in the lineup. You can use it to power the whole car stereo system, mids, highs and a subwoofer from one amplifier!

Featuring a four-channel class A/B output, the Q4-150 offers superb sound quality and enough power to drive arrays of speakers. Its variable high and low pass filters can be used in a bandpass configuration so you’re able to tune and define your sound.

If you’re driving subwoofers with this multiple channel amplifier, take advantage of the bass boost for a low end so thick you can eat it for dinner. The included remote gain control knob comes complete with a clipping indicator so you can keep an eye on your levels while your ears have fun absorbing the sounds.

The Q4-150 is stable at 2 Ohm in stereo and 4 Ohm in mono mode. Its bridge channels can send even more power to select speakers.

Four-way protection circuits and MOSFET switching devices are there to make sure you’re able to enjoy your Q4-150 for years to come.
