A friend has a stereo amp, the SPL DK-2000D and two dual 2ohm Image Dynamic IDQs in a sealed box. Right now they're wired to 4ohms, each on their own channel.
Here's the dilemma I'm having. Source is a Eclipse head deck, with 5v preouts and yet the gain still needs to be set at the max. There's no clipping, and it hits pretty hard, but still I find it REALLY strange that I have to max the gain on the amp. I had to put around 3-4dB of bass boost on. The amp is in LPF mode (full range amp) with the low pass set at 80 or so. The variable subsonic is set as low as possible, 30Hz.
I can't understand the website for the amp, I really have no idea how much power the amp is pushing to the two IDQs. I'm guessing 800RMS @ 4ohms means total, so each channel (sub) is seeing 400?
