Actually if they were combined it would put out 12w at 4 ohms, 24w at 2 ohms, and 65 watts at 8 ohms. The factory units were about 12w TOTAL power. That's about 6watts peak per channel. They work alright, but I must agree. I'd run a Kenwood cassette unit with the shaft style mount to match what you have now, with a cd changer behind the seat. You'll get better sound even from the cassettes. As far as the speaker sizes, the dash is 6x8 not 5x7. A 5x7 will fit because they are dual mount meaning that they will bolt in in a 6x8 opening. The doors should be 6 1/2 as already mentioned.

The factory wiring diagrams state the front and rear channel amps to the radio are wired together in parallel on the trucks.
Parallel would halve the ohms, but increase the watts by 1/2.
So with 6 watt, 8 ohms per channel, on a four channel radio. Combining the front and rear channels would bring it to 12 watts, 4 ohms per speaker. 24 watt total at 2 ohms.

I have 6.5" JL audio speakers in my 86 and they fit perfect.
