hello, I'm stuck on my project because of my frequency burp!
Equipment used:
-2 CS 15 "D1
-2 Banda Viking
-8 Cells 490AH/4500A Yuasa
connected to 0.5 amps fuses are broken
Then connected a 1ohm amps (one per coil subwoofer), frequency is 58hz for a little more real 2ohm.
box reduced the frequency does not rise, I do not understand what this little ahead.
The voltage on burp 14.5V. amplifiers accept a 17.5V to start no more.
I'm able to pass the 0.5 connected?

Very nice build, i notice your using the exact same batteries as us, how are they performing for you? How many do you have?

Id also like to ask you about the Banda amplifiers, how do you find them?

If you have more build photos or information on this build id love to see it because it looks very good and im interested
