  • Punchy Polished Bass!
Size: 2-Channel Style: 2-Channel - 2500 Watts
I just got this amp installed and it functions incredibly well. I use to have a premium lightning audio amp that was a a monoblock D class amp with tremendous output. Unfortunatelly mine died and am going to get it fixed. I tried another amp which was a compact kenwood. TOTAL GARBAGE. I was worried this one was going to sound distorted like the kenwood. This little amp is incredibly powerful! Not only that, but the low bass is super punchy and polished. The 40hz is also polished as well from most amps I have heard. No distortion either I encounted when adjusting the amp and its output. For reference, this is with 2 Kicker Comp C12 subwoofers. ... show more

  • 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

  • El amplificador está en modo protección y no logra encender
Size: 2-Channel Style: 2-Channel - 1500 Watts
El amplificador entró en protección y no lo puedo restablecer. Aunque haya quitado todo el consumo de las bocinas y la entrada de los RCA. Volví a conectar la alimentación solamente y aún así no sale de la protección
