Setting up EQ

[jhiestand]

I just finished installing an EQ (Clarion EQS746) and am not 100% sure how to tune my system with the additional variable -- heck, my system was barely tuned to start with! So here I am looking for some advice on setup and tuning. From what I could glean elsewhere, first is phasing/tuning. I have a boat amp (Hifonics ZX6400) and sub amp (BX1500D) -- I assume the hi-pass on the boat amp should be set to the 100 to 120 Hz range which is approxamately where it was previously. Then the sub amp low-pass should be set higher, like around 180 Hz? This is assuming the EQ low-pass crossover is set to 90 Hz. What is the best way to fine-tune these crossover settings? I do have a bass mechanic CD with test tones. Also, I assume I need to start from scratch again setting the gains on both amps?

Once the above are set, it sounds pretty straight-forward lowering/raising frequencies to clean up to suit how the system sounds. A final question, though. Is there no longer any need for the remote bass control? I'd assume I do the major setting at the amp and then the EQ bass volume would take over that control's functionality?

Thanks in advance!

RE: Setting up EQ

your sub freq. should be lower, but start it at about 120hz just like your speakers. yes you need to set the gains first, then mess w/ the eq. usually you turn it down, not up. there are alot of threads on here about tuning.

jhiestand,

Since the EQ has alot of voltage you'll be gaining your amps down. Stay with the high lowpass setting on your amplifier since you have redundant lowpass crossovers. I don't see the need for duplicate bass controls. Your EQ should give you everything you need at your fingertips.

Shoot me an email and we'll connect by phone. I'll walk you through tuning your amplifiers.

Grew up in Dayton by the way.
