Installing aftermarket sub/amp power questions

Looking to get a larger sub for the factory uhf system, I was curious about the draw on the 12v battery and if it would be wise to install a second 12v to run in parallel to keep the strain off the 12v converter.

Also would it be smart to just use the factory sub wiring as the input for the new amp?

You could use the factory sub wires as high level inputs to an amp, though I would recommend a DSP or some kind of correction device to fix the signal and counteract the roll off. Maybe ignorance is bliss, but I've had close to 1200w (750w sub amp + 400w front stage amp) running on the stock single 12v battery for over a year. I did finally replace the original 12v battery early this year, but it was 5 years old.

good to hear, I have a 1800w although the gain wont be very high

That all said, there is at least one thread of a person whose warranty of the DC/DC converter was voided due to his aftermarket stereo. That didn't dissuade me from going forward with the install anyway, but it's something to keep in mind. If you're out of warranty then no worries.
