Speaker wiring question

[dleininger42]

Hey I'm new here and I just had a question about my system,

My system consist of 1x Kappa 0ne Infinity 800 Watt class-D Mono sub amp pushing 2 infinity kappa 12" subs

1x Kappa Four 4 channel D class amp @ 150 watts pushing my front door Kappa 50.9cs 5-1/4" two way component speakers and 2x Kappa 682.9cf (5"x7") rear door speakers

The other day I noticed that I have pre-cut holes in the back of my car under the rear windshield...these were for the better factory sound system, but my car did not come with that... I was wondering if it would be a good idea to put 2 more Kappa 682.9cf (5"x7") same as my rear door speakers, and would I be able to just put them on the same channel or would I have to wire them in series with my rear door speakers. the rear speakers are 4 ohms with a power range: 2-100 watts RMS (300 watts peak power)

I'm just wondering if this would would even be worth doing.

Thanks

if you did, you'd wire them in parallel with the rear door speakers.

Now, ask yourself this...when you listen to live music...where does it come from? in front of you or behind you? adding another pair of speakers is going to create a bias toward the rear. Those cutouts are there for factory subwoofers, not full range speakers. I would recommend against it, due to sound stage changes. If you're just looking for MORE LOUD and don't care about staging or imaging go for it. it will only cost you the price of speakers and a few feet of speaker wire.
