Thank you for replying. So, since they are 8 ohm speakers I should run them in parallel at 4 ohms? I was thinking about getting another amp but don't know the power rating of the 115DL speakers and didn't want to over load them.
From what I can find the amp is rated for 2-ohms stereo, so 4 ohms is not a problem. :T However, an electronic crossover would be helpful, to divide the high and low frequencies. Forgot to mention that before..
