did exceed my expectations very good amp had it connected on 2 10" memphis subs

My spouse and I installed the system and were pleasantly surprised by the power of this amp. It easily handles our two 12s and we are now thinking of upgrading to two 15s. Overall, we are very satisfied with the product, especially considering the price paid.

This amp is a great deal for the price, but make sure you have good speakers to handle its power. I currently have two 12-inch Boss 2300 watt DVC speakers, and the amp is too loud for them, causing them to pop. I plan to upgrade to a 6000 watt 15-inch speaker for this amp.

I appreciate the single-side connections and the powerful performance of this amp. It easily powers my subs without overheating. It's the best amplifier from Boss that I've seen since the 90s.

The selection may suggest 4000w, but upon reading the title and viewing the pictures, it's clear that it's actually 1600w, which suited my needs perfectly. It greatly enhances the subs, especially my 2 kicker vr 12s that hit hard. Although the bass knob seems non-functional, I am overall very pleased with it.

Experienced issues with protection mode frequently, but when it worked, it performed great. Installer suspected wire set as the cause. Overall, unsure about trying the product again despite its solid build.

The amp I bought was used and missing parts, but I fixed it with spare parts. It was cheap, so I'm not too upset. It works fine, so I won't need a refund.

Does not produce the power it says

I didn't like it not worth it just get a Jensen one

i order the 5000 high output amp yall sent 1500 output its not gonna work
