I managed to get my stereo wired up today. I found the amp turn on wire and that was the only thing holding me back. Anyway, I didn't wire the lows through the preamps on the HU since I'm going to install a sub and want to use those for the amp that's going to drive it. So right now I have the tweeters and 5x7's running off the four channels coming out of the HU. I know this drops the load down to 2 ohms. Will I damage my HU if I keep this configuration? Thanks.
