how t0 wire a 4 0utsource (alpine Headunit) to a 6 speaker setup

[justav6]

should be an easy answer for most of you. i need to hook up 6 speakers in my new work van. the alpine puts out 16 rms and 50 total. to 4 channells. do i tie the dash and door speakers together parallell or inline. ? then use that as fronts? i know im best off getting a 4 chan amp, but dont know how to wire the 6 speakers. any help i appreciate. thanks for the help.

I think the door speaker is only a mid and the dash speaker is only a tweeter. Get a harness and wire it up, it should power all 6 factory speakers with just the 4 channels

appreciate the help. the front doors are 6x9 and the dash is 5-1/4. there were no speakers in the dash just wires. the speakers worked when i hooked them up to the wires. havent installed the alpine yet its still in the old vehicle. i was planning on wiring everything at once, but i havent bought an amp yet. i wasnt planning on using a harness since everything coming out of the headunit will be going through an amp somewhere. am going in the right direction here? also when picking out the amp am i looking for per channel rms to equal the combined rating of the door speakers plus dash speakers?

50-75 watts RMS X 4 ch should be plenty. I have never seen a 6X9 in the door - guess it's a american car manufacturer thing. You may need another 2 channel amp for the dash speakers, or you can wire the door and dash speakers in parallel.

thanks for putting me in the right direction. now im on to step 2, buying the rest of what i need. so now that i have 2ohm draw up front and 4ohm in the rear i have another question. from what i read an amp will put out twice the power to 2 0hm than it does to 4ohm. so if i get say a Profile AP1040 Amplifier ( you said profile is a good choice) which puts out 4 x 80 rms @ 4ohms, good for my rears, but then 4 x 125 rms @ 2 ohm. does that mean that both parallel speakers up front will get 125, or since theres 2 does it get devided by 2? reason i ask is 62 rms is ok for the fronts, but 125 is more than theyre rated to handle. iv been reading what i can, but alot of this is a bit new to me, thanks for the help

The power up front will be shared between the 2 pairs of speakers, so each speaker will receive like 62 watts RMS each (at max power). Not all amps double their power into 2 ohms, it has do with design and power supply capabilities.
