[QUOTE="trumpet, post: 8311854, member: 628688"] Signal summing alone is not likely to get you a flat 20-20,000Hz signal, but it might get you something that looks like a roller coaster ride. Your best option if you really do care about great sound and not just a lot of boom is to pick up a used JBL MS-8. It will do the signal summing and a lot more with automatic calibration. This is the shotgun approach, but it can work extremely well. The other "right" way to do this is to RTA the electrical signals from your factory amplifier, determine your channels to sum and whether you need to reverse polarity to counter a phase shift at your crossover points, determine what kind of input EQ you need to do on your DSP, then once you have your flat(ish) full range signal you tune to your desired curve. Does this sound like something you can manage on your own? [/QUOTE]
