Hey guys,
It's been years since I have done anything audio related, so I forgot quite a bit.
Currently I have a TC Sounds TC-3000 15" sub being powered by a single Alpine PDX 1.1000 . If I can recall it's a dual 2 ohm sub, currently wired to 4 ohms.
With that 1000rms at 4ohm's im barely pushing that sub to it's potential. I would like to get 2000 watts rms to it. So my question is: Can I wire up 2 PXD 1.1000's to the single sub without issues?
The two wiring options that come to mind are to add the 2 amps in parallel, or to wire each amp to each voice coil.
Naturally I would try my best to match the gains with an oscilloscope.
Any issues with this?

Nope. Go for it. I didn't have an O-scope when I did it to my friends set up so I had to use DMM method. Over a year now and he's had 0 issues with it.

More important that matching gain is to ensure the two amps are getting the exact same signal and are in phase to avoid cancellations.

And welcome back.  Where ya been?

Thanks guy's.
Well, I bought a new vehicle and went all out on the stereo the first time around, so I haven't had to touch a stereo for 3 years. Now I want more again haha.
