  • Orion still good after all these years. just unfortunately over rating their amps now
Size: 1-Channel Style: 1-Channel - 4500 Watts
In the 90s when I was a teenager I ran Orion equipment and it was some of the best stuff and they UNDER rated their amps wattage. Unfortunately now days they over rate their amps :( This amp dyno tests to only a about 350 watts...which is still enough to push two shallow mount 12s,,,but not even close to the rating Orion says it is, lol. That being said, I chose to purchase Orion equipment for daughters 2023 Trailblazer. I built some nice boxes that sit behind each front seat (in rear seating foot area), facing backwards, snug in the entire area each box being aprox 2.4 cubic feet, sealed, and allowing for her to have a completely flat rear area with rear seats down and full open cargo area for her heeler dogs. Her rear cargo mat goes from rear of car to back of front seats sitting ontop of the two boxes perfectly. The bass is good...NOT awesome and intense like Orion once was...but these ARE shallow mount 12s in small enclosures (although this is the size they are called for), and again this amp only puts out about 350watts max.... and she is VERY happy with the bass. Myself having had 90s Orion 12s and amps that would crack my windshield..Im a bit disappointed. So have your expectations be reasonable :) Orion does make and sell higher end 12s, and amps, so again for what this equipment is, Id still give it a sold A+ There is no distortion at all, and nothing being pushed beyond its limits, so this should last her for the next 4 or 5 years till she changes vehicles :) ... show more

Easy hookup sounds good, plenty of power for the dd audio 8 inch subwoofer, gets hot but it doesn’t shut off, functions well, bass knob that was included is ok doesnt make much of a difference, nice quality amp for the price and very easy to install

  • Look else where !
Size: 4-Channel Style: 4-Channel - 2500 Watts
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. ... show more

  • Not to bad for the price.

Good amp if you arent pushing really good speakers. I have two orion xtr 6.5 and xtr 6x9. After about 30-40 minutes of constant music playing half volume, the amp gets hot and cut off.
