What are the effects if configured at 0, -3, and -6dB?
Still not sure what value the installer has set when he wired it up.
FYI, seps is MB Quart DSD216.

Personally I like the seps' current highs and SQ, but a passenger complained that the high-freqs are harsh (read: matining).

BTW, my setup has no external amp, no sub. Just the seps and 6x9.

Tnx! :lol:
