Just hooked up my Image Dynamics 12" v3 D4. Have it sealed in a 1.25 cu ft box. Have it on the sub channel of a JL XD700/5. Have the dual voice coils wired parallel so it's 2 ohms (JL XD700/5 should give 300 W RMS @ 2 ohms).
I can barely hear it. I know a signal is getting through, I can put my hand on it and feel it.
Tried turning up the gain slightly on the amp, but the difference is negligible. I even got the yellow overcurrent protection light after about 2 turns (I think even less than 2... it was no more than 3 turns).
I picked up some Hybrid Audio Unity's but don't even have em on the JL amp yet (wanted to wire to HU just so I could see the diff). The sub is the only thing wired to the amp.
Any immediate ideas pop into your head? Could use some troubleshooting advice here.
Thanks in advance.
