Hey guys quick question:

I understand this:

Voltage of the output = sqrt(RMS Power X impedance of the speaker)

Example

Say the amp provides 100WRMS into a 4 ohm speaker:

Voltage = sqrt(100W X 4 ohms)

Voltage = sqrt(400W*ohms)

Voltage = 20V

So I have a 1500W amp and two dual 1 SSD12s.

Would it be?

Voltage = sqrt(1500W x 1 ohm)

Voltage = sqrt(1500W*ohms)

Voltage = 38.7V

Should I use 30HZ, 50HZ, or 100HZ tone?

I dont use a DMM to set my gains, just go by ear. Find out what your head units pre-out voltage is and match that with the gain on the amplifier, the gain is there to match the signal coming from the headunit.

It's 4V.

bump. is this correct?

I prefer to use a 60-80hz tone when using the DMM method.

You will not see a constant 4 volt output on your deck so I wouldn't worry to much about that.

Use your ear as well to listen for stress in the subwoofer and a voltage gauge to monitor your battery voltage.

Is the amp remote a gain remote on the Sundowns?

I'm running Fi SSD12s (2) 800 RMS off of the 1500D V.2.

If I turn the gain all the way up will they clip?

The remote controls the gain, but doesn't go higher than it is set on the amp.

Wide open on the remote is to where you have it set on the amp.

Cool thanks. Based on having two subs that are 800rms each and an amp that provides 1500 will the subs clip if the gain is all the way open?

shouldn't really be an issue, I just wouldn't make a habit of going full tilt with gain wide open... know what I mean?

BTW, is your setup sealed or ported? If ported what did you tune it to? I'm just curious...

ported at 33hz.

just make sure you set your SSF before you get pumpin'
