I got mine drawn up just not built yet. I went 7.25^3ft tuned to 35hz with 2 6" precision ports!

As stated above pull out the radio and check the remote wire connections. I would recommend the relay setup as well. Nobody can actually tell you "why" they turn on don't. It's just one of those situations that takes some simple troubleshooting and a little work with the dmm. Good luck!

In protection or protection l.e.d on? Troubleshoot by checking the power and remote voltage to make sure that they both have 12+ volts with a DMM. Email [email protected]

Bump for updates!

Nice!

I tend to prefer a 35hz tuning. Optimum is 1.75^3ft but it will come down to the vehicle and install as to how it will sound in the end.

Does the sub still work at all?

Manual looks like a type-o. As said above wire + to + and - to - and you should be ok.

When you say the 2.8 fluctuates, what exactly does it measure?

I still say 4 SA-12's tuned to 35hz

What exactly are your goals? SPL? Daily street beat?

4 Sundown SA-12's!

Fixed for you.

Give it a bit before you change the tuning as once the speaker loosens up a bit it will play the lows your looking for!

I love it!

That thing is a monster!

Very solid amplifiers! A little on the pricey side imo.

Sweet looking amplifier!

Great build! Excellent craftsmanship!
