After the console was built/installed, I decided to swap out the bass amp. My old a/d/s P2110 doesn't run extremely well at 2 ohm bridged, and with the subs in series, it limits power too much on the amp, reducing headroom. So I got a Phoenix Gold T500.2, which is just a little more powerful, but most importantly stable at 2 ohms bridged. In the process, I needed upgraded cabling for the additional current draw (used 4 gauge), and also added a 1 farad monitor cap to even out the power supply. It's up to par now.
