Price worthy

The following review is for R2-500X4, which is a part of the bundle you are viewing.

All in one for a simple, clean listening experience. Distortion detection built in so you won’t have to guess max volume when setting the gains. Nice sleek design with the performance to match.

Doesn't disappoint!

The following review is for R2-500X4, which is a part of the bundle you are viewing.

Fantastic mid-level amplifier. Instantly noticed the power and the clearness of the music. Perfect size for under the seat too. Be careful with the gain to start! Don't move it until you already have music playing... it'll kill your ears! Highly recommend!
