2016 Mustang Gt Speaker Upgrade Advise

Hey There,

I've been out of the car audio thing for a while. So any advice would be appreciated.

I have 2016 Mustang Gt Premium

Premium Models 200A/400A (9 Speaker Configuration)

6.5" (Doors) Replaced to Focal

3.5" (Doors) Stock

Tweeters (A Pillars) Replaced to Focal

3.5" Center Channel (In dash) Stock

6.5" (Rear Deck) Replaced to Kicker

(shaker system without sub)

I local Car audio Places installed

front door Focal 165 AS Access 6.5 2way

Read Deck kicker Coaxial ks654

The used stock amp. Stock Head Unit,

and ID8 Image Dynamics Sub woofer in Vended Box(.40in Box) 8in on kicker mono amp

Sounds ok when i park no noises. But when i drive(noises) sound much worst .

Sounds like bass is missing in the front and mid's missing as well.

I'm use to Bose sound system in my other Cars maybe that the problem.

I like to have a sound like Bose sound system in my Mustang clear sound clear bass short bass.

I'm not sure its possible to do in a mustang.

But is still not sound right. Any what can i change.

Would it be better to install the speaker on a better Amp?

Thank u for the advice .
