New Sub not working.......Help me troubleshoot.

[Kfra315 10+ year member]

I've checked all my connections. The LED light on my Amp says its turned on but my sub is not getting any power at all. Since the amp is powering up I can assume the battery and fuse on my battery are fine. My gain is turned up a quarter of the way and the the sub volume on my headunit is turned up to +5. The sub doesnt budge. The most I got was one quick burst out of the sub while I was checkin some connections but nothing since. I know its really hard to troubleshoot without seeing it but i'm just looking for any advice. My equipment is an Alpine MRP-M1000 and a 10" Type R wired at 2 ohms. I'm heading out to check my ground wire now but I really dont think thats a problem......

HU settings? Crossover Freq?

Get a 3.5mm to RCA wire and test the amps inputs with an iPod to rule that out

Think Radio Shack might have one of those?

Its a Kenwood X890. I dont have a crossover and the HU only has an LPF and HPF setting. I've set the LPF to through so that I can control the LPF directly on the amp. Also I forgot to say.......I disconnected my rear factory speakers but the sub wasnt working before I did that so I dont think that will make a difference at all.

The ground is not looking too solid so I'm gonna make a new clean ground to see if that make a difference.
