So my question is ...this is basicly saying that i can connect these wires directly to my stereo's wiring harness(either front left and right or rear left and right)even though the front and rear door speakers are wired to these? I thought if you wired multiple speakers together it changes the ohm load. Also, if i do this, i'm pretty sure the sub out function on my stereo will not apply, but what about if i got the RBCM-250D remote control module...would that work?
If you are going to use the High Level Inputs then it is always best to use the front speakers for the signal source. This will prevent a loss of output from the Tube if you ever use the fader to fade to front.
The Green - Green/Black wires are the positive and negative connections for the left channel while the Grey - Grey/Black wires are the connections for the right channel. The statement of only using one set of speaker OUTPUTS refers to using the front or rear channels of the headunit for the signal source (either or but not both).
You are not wiring multiple speakers together by using the front speakers as your signal source. You are not powering the Tube from this signal, only creating a signal source.
If you want to use the subwoofer out feature of the headunit just use the RCA cables. If not, purchase the RCBM for the 250D which will not only allow for volume adjustment but crossover adjustment as well.
