Help setting up my BRX 2000.1D

[speedyjuarez Premium Member]

Okay so I just got in my BRX 2000.1D and I want to make sure I set up everything the right way.

What should I set my knobs at?

1. Level 9V-0.2V

2. Phase 0-180

3. Bass EQ 0db-10db

4. sub sonic 15hz-35hz

5. Low Pass 35hz-250hz

Is the Level knob the same as the gain?

Okay I found a post from nasty08impala and it helped solve some of my questions.

yea the level knob will only turn up as high as you have the gain on the amp set. If you dont have access to a o-scope then use a DMM to set your gain.

Do you know the pre-out voltage for you HU?

No I don't, Can I check that with my DMM?

It'd be easier to post the model of your headunit.

Head unit KDC HD548U

I'll be running two 15s 800rms each at 56.7 on the DMM. What's also confusing me is that it has two channels, Do I connect each sub to a different channel or do I bridge it?

From what I could find on the internet it says Three 2.5V RCA preamp outputs for optional full range and subwoofer amplifier

your pre-out is similiar to mine. 2.5 is on the low end. so just use a dmm to set the gain

I haven't set a gain going off of the pre out voltage, Do I have to get the 2.5?

I have set my gains before using the DMM but using the formula where you square root to find the values. Never to the pre out voltage, if theres any difference I didn't know.

So my last question... Do I bridge the subs or one to each channel?

you dont really have to know the pre out to set them. With a Dmm you use it to set the "target" voltage for the amp.

what are you wiring the subs to 1, 2, or 4ohms?
