Atom 5.5k pro
"I got this amp awhile back BStock. Let me tell you it looked new inside and out, when hooked up correctly with correct power it ran flawlessly. For the price man I am more than satisfied. This was pretty much brand new minus bass knob. Only recommendation for future is add bass knobs lol. I was so impressed with this I ordered there BStock 7.5k as an upgrade, will review after I run it for a bit but I am very confident it is pristine just like this."
