Customers say
Customers find the amplifier delivers crisp sound and consider it good value for money. The power output receives mixed feedback – while some say it’s incredibly powerful, others report it doesn’t deliver the advertised 4500 watts. Moreover, the amplifier overheats significantly and has durability issues, with customers reporting that the gain knob breaks after minimal use. Additionally, functionality is mixed, with some saying it performs well while others report it stops working.

Look else where !
two channels stopped working just two days past return date. contacted Amazon to do an exchange. What a nightmare. Orion sent me a new email asking question’s for three straight days . Finally after that I was emailed a UPS tag and item return number. After Orion had the amp in there hands for over 20 days I sent and email to customer support with all tracking and return numbers looking for a return date. received no response. Contacted Amazon support to see if they could help. All Amazon could do was summit a report to Orion. Not vary helpful.After Orion had the amp in there hands for 30 days I recieved a email with a tracking number from Orion. No other info.They sent me back a amp that was covered in black smoke and dirty finger prints. Not mine! The amp smelled like a wire fire really bad. Now my truck smells like a wire fire.Vary disappointed in this entire experience. Orion sucks.

Read for RMS
It was a pretty good deal until I went back read through the description about the RMS it only put out 80w that is basically hooking it starting to my factory radio to supply the power for it.

Works as expected!

Works great. I doubt it’s 4500 Watts but it’s atleast 1600 Watts. Doesn’t overheat or ground out. Pushes two 12 inch subs no problem.

Took a few months to get hooked up! Amplifier is defective! A complete waste of money! Constantly surges out as soon as you turn it on! I had to buy another amplifier! DO NOT BUY THIS AMP!
