Knotscott to be honest no, what would I need to accomplish that? I can google :)
Anytime you can relieve your main amps of some stress, by sharing it’s bass duty with another capable amp, there are advantages and potential for better sound. There are always a bunch of variables, but it could take your SQ next level. There are multiple ways to approach, with pros and cons for each, but you can start simple, and expand on it.
The simplest approach would be to use a good sub or two with a high pass filter to handle the bottom end. You can run your main amps and speakers through the sub's built in high pass filter to alleviate the strain of large power sucking low frequencies.
You could also add another amp for the main speaker woofer’s, using the current passive crossover (you’d need a method of matching volume). If you’re willing to bypass the passive woofer crossover, you could add a simple active crossover, or you could go further with DSP and a more complex active crossover. You could also bypass the midbass high pass passive crossover on your. However far you want to take it.
