okay... I'm new to car audio. what would be the benefit of enabling the crossovers on my 4 channel amp that are only powering my speakers, not subs. Head unit is aftermarket Stinger 10"
Benefit is sending frequencies to speakers that don't support them will muddy the sound.
Granted, I am no expert but would suggest you hit up a car audio site for better help in tuning your setup unless you are satisfied simply adding the additional power punch.
