I think I am going to buy a Pioneer AppRadio 3, but noticed it only has 2 RCA pre-outs at 2V. The higher end units have 3 outputs at 4V. I am not sure what effect it'll have for me having 2V vs. 4V. One of the RCA outputs you can set to be subwoofer output, or you can have it as rear. I was wondering how could I have an amplifier for 4 channels + one for the sub and only have the 2 RCA's?
If I went with a JL amplifier such as their XD700/5, took the one RCA that is for front, put a "Y" splitter on it, plugged them in to channels 1,2,3,4, then used the other set of RCA's and set it to sub; would that be the advised approach? I am also thinking of buying the JL Stealthbox for the 2012+ Tacoma, replacing my front and rear speakers. If the headunit had 3 sets of RCA's this could be easier.
I don't know if losing the "fader" control is a huge deal. I would still have "balance" (left/right), but not fader for front to rear. Is there a way to control that on the amplifier somehow so that while it cant be controlled on the HU, I could get it to the right spot and then set-it and forget-it?
