Built around the TPA3118, Higher Power is a 60W class d solid state power amp solution. 

Don't be fooled, it'll push your 4x12 plenty but it shines on a 1x12 or 2x12 at bedroom levels. The buffer inside sets up your signal with a nice flat response going into the power section so you can drop your favorite preamp pedals in front.

Output impedance of 4-16ohm. 

Designed to be fed with 24VDC center negative. It can run on as little as 9v with power scaling down to approximately ~10W. This is not recommended to be powered by your daisy chain or iso-supply. Recommended to be ran on its own power supply. (sold separately by others).


Do not use a class d power amp with an attenuator/loadbox. It’s not necessary and it will damage one or the other. Consult your attenuators manual first. For example, Torpedo products specifically state they are safe for solid state amps.

Around the house I typically use a One Spot (nothing else on it) for 9v and it's stupid loud for my basement through my 4x12. 

Here is a 18vdc center negative option from LoveMySwitches:

If you're interested in getting the maximum out of it, you could go with a 24VDC supply like this one: but you will require a polarity reverser to make the center positive become center negative:

    It is very practical and easy to use and of very good quality, I am very happy, and even happier using it in stereo mode. I recommend it
