Need help with amp

[Shanerf150]

Hey guys. New to the forum. I use to install back in the day. Now that I’m 44 I try to not install anything. My 19 year old has a 2012 GMC Sierra 1500. We put new speakers in it, added a backup camera, Bluetooth , xm, etc. everything works fine but the amp. It’s a JP8 from down4sound. We are trying to run 2-12” comp rt’s. The subs are 2ohm dvc. I have each sub wired in series for a 4 ohm load and then paralleled . The amp is mono but has 2 speaker inputs. It’s frustrating because I’ve checked voltage, the subs, wiring . Checked to make sure the pre out is on in the radio. Please help. Am I missing something obvious??

The 2 sets of speaker inputs are summed. The best you can do is a 2 ohm final load unless you wanna try .5 and risk frying it.

Unless you just got a dud which can happen. Did you get it signed?

No he didn’t get it signed. I’m beginning to wonder if it’s a dud .

Maybe contact D4S and go from there. I’m sure he’ll swap it out no questions asked.

Go have somebody bench test the amp.
