How do you wire EQ's

[ccrider540]

I was looking at a diagram and it just shows one set of rca's going from the hu to the eq, so i was wondering what you do if you have 3 pre amp outputs on the hu?

You only use one Output... I used the 'front' output on my head unit.

oh okay, so then would i have to turn off the high pass filter in the hu and set all the eq's to 0?

I use the FRONT one too. Just to let you know, using the SUB output will render your mids/high useless.

Yup. Turn HPF off on HU. You could, if you wanted, use the HU EQ. I don't though.

wait so your saying if i use the sub out on the hu it will render the mids/highs useless?

The third output on your deck is a subwoofer signal (Low pass) If you were to hook that up the the EQ, you wouldn't be sending the right signal/ frequency for Mids/ highs. Personally, I don't even use the EQ for subs.... Just my door speakers. On my EQ, I lost some lows by running it through the EQ.

It was opposite for me. I ran the subs to the HU and mids/highs through the EQ and lost a lot of bass. It sounded horrible. Reconnected the sub to the EQ and it helped a lot. I guess it all depends on the EQ. Mines has a "subwoofer" knob so I suppose that helps.

Oh okay ya i figure the sub out on the hu would do that.

or maybe it just upped your output voltage to your amps?

Line driver FTW on sub stage
