Aug 2013: Love it when things come together. 80W stereo Response Amp (160W) running bridged into a dual 250W(?) voice coil Vifa Subwoofer Driver, (12" version), coils wired in series, with a grille on the front, in a ported house.
FAIL! Antenna power cable only gives power when the radio is on... I had to rewire this and I chose to power on the amp from the ACC/ignition trigger cable on the radio. This way the amp can be on regardless of the radio, not perfect but better.
100K Ohm resistor on the switch LED, or something. LED was too bright...
New soldering technique for piggy backing cables, without getting too angry, this is good.
Waiting for boss stereo attenuator, need to wire the juicy cables in the mean time..
Wired in the amp and the speaker today... all works well.
The Boss attenuator arrived today, bout a week earlier than I expected, I finished the install today, just in time for rollers on Fresh FM!
There is one thing I can still do, I wired a cable from the amp up behind the steering wheel which is for remote volume control for the amp, but I lost the volume knob... maybe a job for another day.
