Rob B asked:
I have MB Quart premium component 6.5s in my door. If I install an amp that has crossovers in it (A JL 300/4) would it be better to use the speaker’s crossovers or the amp’s?
Wait, you guys saying yes use the amp’s or yes use the speakers’?
You should (it will make your car better!)
yes keeps from blowing them holla in out
yes use both crossovers

I though i might clarify that one for ya
Crossovers area meant to handle extra power and are probably a bit better than the crossover in your amp its just a double filter for superb quality mids and highs
