Currently i drive a Renault Clio 2004 Model.
the 4 doors currently have 5.25" Lanzar VC52 (70w/140Max) 2 way coaxial speakers in them.
since i'm keeping the stock deck i have decided to use the Audiocontrol LC7 which will allow me to use a ipod or other mp3 player (since the stock deck is weak) and also give a little kick.

Now i'm only keeping the stock deck because its actually my father's ride and i dont wanna spend too much on the setup.

1.
Now here's the fun part i'm thinking of purchasing a RF T400-4(60W x 4) to power the door speakers (they will be running on the builtin highpass xover), but i'm also thinking about get the T600-4 (100w x 4) instead for the door speaker. i dont know for sure about feeding them an extra 30w.

2. Eventually i'll be getting a sub, i'm looking at a 15" RE SX with a T1000-1bd feeding it.

So my question is can those 4 5.25" keep up with a 1000w 15"?
What about the 4 5.25" with Dynamatted doors?
or will i have to upgrade to 6.5"/add more speakers

3. (Extra Question)
If i do the Big 3 mod will a ground kit still be beneficial? (.do note that i'm not to familiar with the ground kit)

 

nevermind i've got my questions answered
