So far i have purchased

Alpine SWS-1243D subwoofer
Alpine MRP-M500 - Amplifier - 1-channel
and a Sub box which fits nicely behind the drivers seat

Alpine SPR-17S 6.5" Component Speakers (which are goin to replace the door speakers and tweeters)

JL Audio C2-600X (which are going to replace the subs that are built in behind the drivers and passengers seats. i am goin to change them to get treble instead of the bass)

i was told if i can an amp to run the Alpine it will over power the JL or and amp to power the JL will under power the Alpine.

so would i be better to get another set of Alpines and have more tweeters near the head rest? or get these Alpine SPR-17C 6.5" Type-R Speakers which come without tweeters.

i dont have an amp for the speakers yet so any recommendations would be good. don't care about the price.

also do i need anything else to install this? should i get a capacitor to help it out? if so what kind

im not changing the head unit either.

im gonna get a professional to install all this but i want to get it myself as it will save me some money.

thank you
