how many channels? 300 rms? make and model?

4 4ohm speakers. 2 6.5", 2 6x9"
Installing an amp
Can I wire one of the 6.5's and one of the 6x9s in parallel? (The other two would be wired in parallel as well.) Both have the same resistance rating, but I just want to make sure that because they are different sizes that it will not cause any problems.

something like this, I'm wanting to put a 2 ohm load on the amp per channel.

If the amp can handle it, thespeakers don't know the difference. Remember that THD doubles when resistance is halved. Subs it is not anissue, but depending on what you have, it could on full range.

THD is .5% at 2 ohms, I can live with that. Just wanting to make sure that wiring a 6.5 to a 6x9 isnt gonna cause another catastrophic hot-pocket electrical meltdown

You would be better off to wire them in series and push up to 8 ohms, 2 ohm is very hard on the amp even if it can handle it, it will take a lot of amps to get good sounds out of them.

You will be fine doing that. What is the resistance stability of the amp? I know a lot of new amps out there are 1 ohm stable and live just fine there.

its stable to 2 ohms. just a little 4 channel kicker amp

What are you using the other two channels for?

yeah use what are you using the other channels for that would be the best option

Using the other two channels would present a 4 ohm load on the amplifier, producing maybe 30 watts per speaker. That's not much louder than I already have on the head unit. By wiring it down to 2 ohms, I would be running at 50 watts rms per speaker, more than double what the current head unit is producing. And with an amp, of course it will sound much cleaner.

I'm a little rusty on my electrical theory, but I'm pretty sure running in parallel is not going to increase amperage running through each speaker (because the actual resistance at the speaker is not changed), just the amperage seen at the amplifier (because effective resistance of the circuit is reduced). (compared to running two speakers on indivdual circuits, not running two in series)

After looking over this a few times, what I'm trying to do isn't going to work. Going to have to run each speaker to its own channel. I was trying to go around this because I only have one set of outputs on my head unit.
