Wiring for 8 ohm speaker and 4 ohm sub

judging by the site and that guys post. i dont feel to confident about buying that model. Do you own one of those? any other sets like that you have in mind.... For 160 i dont mind geting it pre-made especially when there is 400watts all i would need is 1.

For example should i just two pairs of these.

If i buy the second pair i get 50% so it would be about 240 for all 4. That would be about 300watts. I would then make the box and put one of these at each corner of the box and then ill put the sub right in the middle.

Or

I can just buy that already premade ones and get a box for the sub and make it  1peavy on the left and 1 peavy on the right and the sub in the middle.

But how much more power would the peavy speakers need then the eclipses?.. What would sound better if i was standin outside the car? inside the car? Any difference at all?

Sorry im a newbie just trying to pick your brain.

thanx for all your help man.

Man you are talking apples and oranges here. 

So what do you want: normal speakers for your vehicle, or external party speakers?  You can't easily get both.  Those 6X9's are designed for use as normal car audio mains.  Could you crank them up and "hear it" outside the vehicle?  Sure, just like any other speakers.

Those Peavy PA speakers (and others like them) are NOT for use inside your vehicle as your normal everyday stereo mains.  They are something you could carry to your party and power them from a car stereo amp.  They are designed for professional sound reinforcement, just like those Selenium woofers you linked to.

Yes, the Peavy speakers sound pretty good, especially for the money.  There are better choices if you are interested in SQ, but those would suffice for a "tailgate party" like you describe.  Sweetwater is a reputable professional audio supplier.

For chrissakes don't obsess about "power" that means next to nothing.  First decide what it is you WANT.

Okay so im going to go with the eclipses. I want something i can add to my existing interiors to give me some more sound and i want something that if i crank them up that i can hear them outside my vehicle.. so yeah im going to go with those and just get a type x and slap it right in the middle of the box. Run them all @ 4 ohms. Get two amps so i can turn on and off the subs and/or the speakers.

thanx
