Sounds to me that shop has no ******* clue what they are talking about... Very curious as to what "12 volts out the speaker outputs" was measured from them. AC voltage? With a load? Did they even set gains?
That amp will do over 1800 watts rms no problem. I've had 11 of these amps and they are great.
Go back to that shop again and show them this youtube vid...https://www.youtube.com/watch?v=C99S7lCaP0oI don't think I'm going to keep the amp though. I didn't know it only allows 8 gauge wiring and mine is 4 gauge, plus the shop trash talked the shit out of them saying that the amp can't output 1800W at 2 ohms with 8 gauge wire. I'm hesitant now.
They dont even know what an amp dyno is. He said he showed them the video and they laughed at it. Definitely one of those JL, Rockford and alarms brick and mortar shops that have no fking clue about anything other than what they sold for decades.Go back to that shop again and show them this youtube vid...https://www.youtube.com/watch?v=C99S7lCaP0o
Then I wanna see the expressions on their faces when they're done watching it.
Btw be sure to visit that audio shop to laugh in their faceJust wanted to give you all an update on this. I got the replacement amp and plugged it up, still no bass. I did additional troubleshooting again (swapped RCA's, remote turn on wire, speaker wire, different subs); still nothing. I then hooked up my Y-Split RCA to AUX cable from the amp to my phone alongside a subwoofer I had laying around and boom, it worked. Right there it told me the RCA outputs on my head unit was bad. I was on a budget with the holidays so I picked up a Pioneer M-S622BS head unit, hooked everything back up and voila, I was back to boomin'. I went with Pioneer because I burned through 2 Kenwood eXcelon head units, each one year apart.
