I'm new to this site and had a scan through to see if i could find anything that resembles my query, but i couldn't find anything, so here i am!
I've purchased a new head unit and a small setup for my car containing the following...
- 2 x 6x9's @ 250rms
- 2 x 16cm components @ 175rms
- 1 x 2ch amp 300rms @ 2ohm
- 1 x 2ch amp 200rms @ 2ohm
...on the basis that i can run it al @ 2ohm and get the maximum for my money, GREAT!
It's been awhile since i last did any car audio, and when it came to planning the wiring, i'm not sure whether i've over purchased, or i'm just thinking too much into it and assuming wrongly.
So, my question is, if i run the speaker sets in parallel, does that mean they'll just take up one channel each, so i can run the 2 pairs, from the 2 (300rms @ 2ohm) channels?
If not, and i just connect them one to each channel, this will be a lower wattage @ 4ohm, right? ...so how would i run them @ 2ohm?

To produce four discrete channels of sound (LF, RF, LR, RR) you will need to run four amplifier channels. Wiring two identical speakers together in parallel typically means you will be halving the resistance, and they will produce (mostly) the same sounds.
Wiring two different speakers in parallel will do weird things and can be interesting, but is not recommended unless you know what you are doing. Passive crossover networks can be built to accomodate different impedance curves and driver efficiencies, but it doesn't sound like this is what you are into.
Amps running at 4 ohms instead of 2 will overheat less, sound better (more headroom) and it is my guess you will still have far more power than those speakers could possibly absorb without damage, unless you cross them pretty high..
