[QUOTE="Steve16Accord, post: 8659868, member: 675837"] Over the weekend, I disconnected the rear speakers at the amp and am only running the components up front now. I re-tuned the amp, adjusted the crossover again, and fine tuned the sub and everything sounds great so far. I haven't pushed the system enough to cause the amp to go into protect mode, but I'll keep an eye on things. In the past, I loved having that higher bass output, but as I'm growing more knowledgeable, I have started to change my focus towards the SQ spectrum. Now it's trying to find that "perfect" balance. This recent change surprised me. The lack of rear speakers isn't as noticeable as I thought it would be. Sound staging has improved, but the "brightness" of the hard dome tweeters up front are a bit much. Once I put in soft domes, I am sure I will like what I hear even more. I am also trying to figure out how I can best move the tweeters lower, out of the sail panels and closer to the mid. I know this would require some moderate to extensive custom work, but I'm confident it will only improve the SQ and staging. I am also planning on getting a DSP at some point within the next year. I am trying to decide between the AudioControl DM-810 or the Audison Bit One (leaning towards the latter). No matter which route I go, I am going to ditch the 5-channel amp in favor of a 4-channel to drive the tweeters and mids up in the front, plus remove the passive crossovers and go active via the DSP. For the sub, I'll find a monoblock amp that offers an equal amount of power output in relation to the 4-channel.
