Well thanks for the info.... These pro audio speakers tried looking for them can cant find them could I get link... The thing is I stink have these 2 pair of sonys I spent $70 a set so I would still be using them...I know it would get crazy but I'm shooting to the wow factor that's the main reason I went and got myself an 18 inch sub.... But I will look at the pro audio and see what I can come up with and I ll run the ppi 900.4 for 4 sonys and 4 pros if I get them
you can sell those sonys or just use them for rear fill no need to buy another matching pair.

Pro Audio
Here's some good pro audio and super tweets set. pretty much 100 dollars for 2 PA mids and 2 super tweets. then the rest on more pa mids. you only need 2-4 super tweets, anymore will seriously hurt/damage your ears and the passengers of the cars driving next to yours.
If you are going for cone area, why not just do 8" or 10 inch speakers? You'll get a lot more midbass out of it and it'll be overall cheaper a lot of competitors use 10" pro audios in their doors to get that chest kick midbass and the lower deep male vocals.
one of the cheaper 10s.

On the CHEAPER side:
Despite the reputation that pyle has, these pro audio of theirs are actually not bad, they are just like all the other off the shelf pro audio mids. Clear loud and Hella Cheap. These are 8 ohms so you can pretty much wire 8 of them to the two front channel of your ppi p900(2 ohm final impedance for each channel) and use the crossovers on that amp to cross them over around 3000-5000hz then use the rears to power the tweets and cross them over to pick up where you left off on the mids or if you feel there's a peaky or harsh part like in the 6k hz area, you can cross the tweeters up to 7k hz and it'll smooth out that peak in the 6k hz area. However if you have a good SQ head unit, most likely you wont have this problem at all.

Dont be afraid of the power ratings. You can give these speakers 25 watts and they will still scream. Hence the magic of sensitivity.
One of our members tried these pyles for his application and loved them, he was surprised at the sound quality for it being pyle lol.
Also when you install them, make sure they are all in their sealed off in their own chambers or else you'll have phasing issues if you just have an infinite baffle setup with all those speakers fighting against eachother.
