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.

    This is a beautiful amp right here. Puts out over rated power. It’s a high quality Korean amp. On sale right now. Cant beat the price for a 4 channel Korean mids and highs amp. Sounds so clean.With the gains and crossovers set correctly this this amp sounds so clean even at full tilt. Love it. Getting another one soon.

    Follow up review. Amp is still running great. I love it. People can actually hear my mids and highs with the bass playing full tilt (4 15’s on over 4000 watts) and I always get complements on how clean it sounds. The amp puts out 1,000 and I’m only using about 800 watts. I’m running 4 – 6.5 200 rms mids on this amp and I use a separate amp for my 4 super tweeters. I was debating between the S4-100 and the Q4-150 and I’m so glad I chose the Q4-150. I am going to get a S4-100 for my Super Tweeters and also another Q4-150 to run 4 more mids very soon. I do recommend putting a fan on it if you’re going to run full till for long periods when its hot outside but thats with any amp. Great build quality, looks badass. You wont be disappointed.

    I can’t belive nobody else has commented on this amp yet. I love this amp. Its never overheated and Its not only got the power, but it sounds so clean. Very impressive. If you want to be able to hear youre mids and highs along with 158.4db 4 sq 15’s and u want them to sound CLEAN, for $330 you cannot go wrong. With it dialed in correctly on enough power this amp will not dissapoint. This is my 3rd comment. Im not kissin ass, I just love this amp. @locallyhatedspl. Instagram. Keep up the great work SoundQubed!

    Very clean Korean amp. I probably got this at the best deal back when it was on sale for $250 in 2020. Unfortunately I’m not using it for the build I wanted to use it for, but I will definitely save it for a better build
