CT SoundsCT-80.4D Full-Range Class D 4 Channel Car Audio Amplifier, 480 Watts RMS

I am using this on a 9 speaker system for a man cave powering it with a 50A 12v power supply. Speakers are inexpensive 8” Pyle 50w RMS 250w peak ceiling speakers . They are wired so that 6.5 ohms is the impedance at the amp. I personally would never run 2 ohms or less on any amp, despite it’s claim to support it. I prefer 6 to 8 ohms. Amp will run nice and cool and will last forever. If not loud enough, I get a bigger amp! I don’t overdrive the MOSFETS by dropping the load impedance. I chose this one for the low and high pass filters built in. They work very well. I have two channels feeding 8 mid/high speakers, and the other two bridged to run a 12 in sub (dual coil wired for 8 ohms). At 50% gain it gets plenty loud, sounds real clean and barely gets warm. Totally rocks the man cave. I am pleased with it so far.

Ct stuff is awesome

The Amp powers 4 infinity speakers in a 2 door 04 Silverado Limited space and mounted on top of the sub box fits perfectly. Also put sub amp on the bass box and its a perfect fit. This amp replaced a Kenwood same wattage and This amp blows the Kenwood away. I was impressed day one and still impressed today.

The media could not be loaded. Powerful compact amp, be aware due to its compact size it gets extremely hot. But overall great sound quality very loud, I love the Phillips head screws for connections instead of Alan keys

I’ve done quite a few car audio installs in my life, so I understand how to match specs like wattage and ohms. I’ve matched this amp perfectly with the true RMS wattage values. No bridging channels or anything actually complicated, just four channels at 4 ohms, 80 watts RMS per channel on full pass, gains less than half w/no clipping.During the setting of gains and crossovers I noticed that it was getting hot but I didn’t run it for more than a couple of songs straight. So I guess to make a long story short, this amp overheated the first time it was at a decent enjoyable volume for a half an hour. I then switched it to high pass frequency thinking it would put a lot less strain on it, but the same results. This amp is a huge disappointment.Only good for frying eggs!

Don’t put out advertised power, very disappointing

Running 2 D&D 10 inch subs. Custom box pushing them pretty good. Can easily blow them, I really don't want to recone my subs.

Pretty compact little amp so it's easy to mount . It's a class A/B amp so sound quality is outstanding, but you get a little more heat with this kind of topology. Overall the build quality and sound quality are both equally amazing
