2V preouts are fine. The only difference (and it's a pretty moot point) is that the higher preouts are less susceptible to noise issues. The s/n difference between the 2V and 4V is theoretically only a few dB anyway and you would only see that at max volume where the s/n is at its highest. Moot like I said. I have a 1500D and an Alpine with 2V preouts and the gain at about 1/4 rocked the house with a single 12. I think you either have a configuration problem with the HU/amp or something wired wrong.
