Upgrading door speakers with amp

Looking to upgrade my audio system. What I want to do is install the focal plug and play door speakers and tweeters. I already have a sub and a dedicated amp for the subwoofer. I want to know how am I able to wire it all together. I was planning on just adding a sub and amp but I am now looking to do everything. I will be getting a Mr marv custom sub box. I will be using stock head unit entune II non jbl. I’ve been researching to forums/googling for my sub amp setup. The back storage bins will be removed and the sub box will take that space. I will be mouning my sub amp under drivers seat, not sure if I can stuff a loc and door amp under passenger seat.




What I want to know/ what do I need?

-Would I be able to just run a kicker key amp for doors and tweets so I could save some space while running a subwoofer and dedicated amp?

-Would there be a better way to pump more power to my door speakers when I do upgrade it. Not looking to exceed 75 watts for my doors.

-How do I wire all these things. I will most likely have a shop do the install.

-Will I need to make my own harness?

Not sure if any of this makes sense, this is my first vehicle I want to upgrade the stereo with.


Thanks in advance,

I'm confused. Are you having a shop do it, or are you doing it?

 

I would get a kicker key amp for your mains, and this 500x1 amp for your sub.

Kicker PXA500.1-500-Watt Mono Subwoofer Amplifier

Both of these amps have line level input so you dont need to get some cheap chinese line out converter and have more crap behind your dash.

Order the mounting plate from taco tunes that bolts under your drivers seat. Both amps are about the same size and you'll have plenty of room for an easy install.
