Sub install blog for my 1997 90 series Toyota Prado:
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.
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.
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.
I had to take the cover off the front dash again, just to confirm the polarities on the speaker cables, didnt want one channel to be on the opposite phase to the other…
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.
