The amp can only see one set as the circuitry is designed for only a 2 ohm inverted signal (BTL) and can only be used on seperate coils, there is no way to run our little stock amps more than 40 watts at 2 ohms.
Can you elaborate on this a bit? If wiring a 2ohm SVC woofer with one set of wires works as well as wiring a 2ohm DVC woofer in parallel with both sets of wires, why would Jeep bother with a DVC woofer at all? Am I correct in thinking that both wiring scenarios produce a 2ohm load with a BTL amp (which is a bit counter-intuitive...or at least uncommon)?
Most threads that turn up when searching for "console subwoofer" and the like usually present differing information, and it's easy to see why: It would seem that BTL amps are rare in the aftermarket/consumer car audio space. We should try and set the record straight here.
As an aside, do you know if this amp have any crossovers? My ears are telling me that the dash/soundbar speakers run through a HP filter and the sub runs through a LP filter, but there just doesn't seem to be enough bits on that amp to accomplish this. My main question is, would I have to run new speaker wire to the dash/sound pods if I disconnected the subwoofer amp?
As none of this pertains to any other Jeep but the TJ, I would say this belongs in the TJ Technical forum, but I digress...
Edit: If this thing had crossovers, there would be a set of input and
output wires for the front/rear speakers...I guess it just takes those four channels as input and mixes them into a mono signal that is output to the subwoofer.
