This will make me look dumb

About to start my first install,

Im getting a sundown 100.4 amp, is it a problem that my front speakers are 4 oh and my rears are 2 ohm.

Will I need to do any special wiring like you do for subs or does that not work with door speakers?

Or would it be easier just to get a 2 ohm front speaker instead?

Fronts are Alpine spr-17s, Rears are Infinity Kappa 5x7's although I still might change these up.

you should be fine. 4ch amp, 2 ohm stable stereo correct?

What do you mean 2 ohm stable stereo?

Wil each 2 ohm speaker get 150 watts, and each 4 ohm speaker get 100 watts is it simple as that?

put the 2 ohms up front and the 4 ohms in the bac,

probably sound better

I doubt my infinity kapp 5x7 will sound better than my Alpine spr-17s. But I do get your idea, so I might just try and find a good set of2 ohm components for the front, and sell my Alpine spr-17s speakers. I havent used them so I could just take them back to bestbuy.

I found that mixing 2 ohm on left side and 4 ohm on right worked best for me.

yea move your componets to the rear and put the 5x7's up front

should have got them on ebay, they're like 100 not 300, just letting you know sir...

If you think the back is going to overpower the front just watch the gains on the rear channels and blend it to whatever sounds best.

Im an employee so I got them far below 100. haha. Im less worried about the back over powering them, I just wasnt sure if I wired doors in parallel or something (i didnt actually think people did this for components) then I could get my 2 ohm load or something like that. but then songs would send the amp a straight signal and the amp would be throwing that signal every which way because of the wiring.

2 ohm stereo = amp can run at 2 ohm as long as it's not bridged. bridged is 4 ohm stable. (bridged is using 2 chs as 1)

so you should be able to just wire the front up to 2 ch of the amp at 4 ohm, and the other 2 at 2 ohms. i dont see a problem at all.

your back isn't gonna overpower your front...

You might not even hear the back at all.

I run the sundown 100.4 off of a pair of ID 6.5s for the front and a pair of ID 6.5s in the rear.

The fronts get 100w per driver, the rear gets 150w per driver.

The rear is LP-d somewhere in the 500hz-700hz range and the fronts are HP-d around 400-500hz.

I did that just so i could get some of the rear fill audible while not sounding "off."

It sounds great but if i were to just full pass both front and rear, you cannot hear the rear whatsoever.

Talk about missing a lot of music reproduction...
