So, I'm getting ready to install some new stereo equipment in my 2011 WRX. Here's the plan:
- Stock Head Unit
- JL CleanSweep (processor)
- JL XD700/5 (5-channel amp)
- Focal IS165 (Component Speakers) for the front
- Stock 6.5" speakers for the rear
- 10" Sub (this will be "Stage 2" and the sub will depend on how much bass I think I need)
The Focal component speakers have built-in crossovers, so there is no separate box to install. I would like to run the tweeter and woofer from the front amp channels 1 & 2. I would then use channels 3 & 4 for the rear speakers.
My questions are:
1. If I run the tweeter and woofer on the same channel, what is the difference if I run them in series (Amp to woofer to tweeter) vs. in parallel (Amp to woofer, separate run from Amp to tweeter)? It seems like the stock components are run in series...they have the same color code, and I think they are spliced together somewhere in the wiring harness - correct me if I'm wrong.
2. Do I have to limit the power to the front channels since the tweeters can't handle as much power as the woofers, or will the speakers be able to limit the power by themselves? I think the speakers each have their own cap and/or resistor built-in, and the rating on the box just says 70W RMS. The amp puts out a max of 75W RMS per channel.
Thanks in advance for the help. If no one knows, I'll just have to play around with it at low gains and gradually go up.
