I've finally decided to tackle the stereo system on my truck, and i've discovered that my knowledge in this department is seriously lacking. There is no "car audio" section on mud, so hopefully there are some experts here in the 80-section that can help me figure this out.
My truck (1996) has the factory "9 speaker" sound system. I bought new head unit (Kenwood DDX-9907XR).
I will be replacing the 2 dash speakers, 2 front door speakers, 2 rear door speakers and the factory sub. I will not be using the rear roof speakers.
So here are my questions:
1) In factory configuration, dash and front door speakers run off the same wires from the factory amp. The door speakers i want to use are rated 50W RMS each, and the dash speakers i want to use are rated 25W RMS. Lets say i get an aftermarket amp that outputs 75W RMS per channel and connect it to original wiring that will feed both the door and the dash speaker. Will it split the 75W to the dash/door speakers equally (37.5W each), potentially blowing the smaller dash speaker at full volume?
2) Is it possible to limit the output of the amplifier to specific channels? For example - 75W RMS to front two channels, but only 25W RMS to rear channels (to avoid blowing much smaller, rear door speakers)
3) The head unit outputs 4x22W RMS and has 5V pre-amp outs. Does it supply signal to BOTH amplified and non-amplified outs simultaneously? If so, would it be possible to run the front dash speakers off the head unit, rear door speakers off the other two HU amplified channels, and then hook up a 4 channel amplifier to the non-amplified output on the HU? Then use 2 channels on the amp for the front door speakers, and then bridge the other 2 channels and use that for the small (6-8") sub in the rear?
4) I want to use the smallest possible amplifier and mount it in the stock location, completely out of sight. I never owned a vehicle with aftermarket amplifier. If i wire everything like i described in #3 above, will i be able to control all the volume of the system with JUST the master volume button on the head unit? In other words, i dont want to EVER mess with the the controls/adjustments on the amplifier. Is this possible?
