install aftermarket amplifier on Kizashi base without Rockford system

[SAEED_KIZZY]

yesterday my friend brought his car to me to install a new Chinese android head unit TS200. He bought it for around 240$.
everything was straightforward, cable and OE connector made the install so easy.

and after install

and my conclusion:
pros:
1- cheap HU
2- very good sound quality without any amplifier
3- simple install little wiring (only for the rear camera) everything is OE
4- good Android OS

cons:
1- large LCD: cover some parts of the front AC ventilator
2- lack of security in case of rubbery: OE HU has 2 screws to mount HU into the car dashboard this one did not.


overall new design for Kizashi which I do not like very much

last four years I try to tune my after-market amplifier to car speakers (I bought a whole set of Rockford OE speakers) but was never satisfied with the result, especially the 8" subwoofer so I decided to buy an OE amplifier from EBAY and try it out.
the amp is cheap around 65$ with original connectors stuck to it but without an amp bracket, I figured I can build one no problem. my car HU is a JVC unit that has pre-amp low-level signal output so it can be used to send a signal to AMP.
the hard part of this job was wiring but with a lot of soldering I managed to install OE AMP into my car and it worked

USB charging port for the back seat:
most new cars have a rear seat charging port I think why not mine so I bought a cheap Chinese charger with TYPE C and a voltmeter to show the car battery voltage and also one On/Off key which I don't want to use because I want to wire charger to ACC power, not battery so every I turn off the car this device also goes to off mode and I looked at the wiring diagram and found out there are two power outlet one beside USB port and another one in console box this one capable of powering 15A power and no other devices are connected to this fuse, my charger need only 3A(max) so this is safe to drive it from power outlet NO.2 wire with no additional fuse beside it is near my charger too. after some drilling and aftermarket wiring, it's done

Rear View Camera:
back in 2018, I bought an aftermarket rearview camera from Ali Express worked for 4 years, and then quit, I decided to buy OE with this PN
39970-57L00-000 BACK EYE CAMERA ASSY, Suzuki
unfortunately, the price is 257$ and it is high I bought another aftermarket from the local store for around 10$ and built the blastic pipe to mount it with the required steep angle to cover the back area of the car.

I have a peculiar problem only front door speakers and tweeters are not working.
The centre speaker on the dash is working unable to understand the fault.

Mine is a base trim non RF no woofer OEM setup

welcome Satya166.
both front doors or just one?

[Satya166]

Both front doors sir
Main speaker and the tweeter.
I tried FM and USB in both cases I didn't get any sound output.

[SAEED_KIZZY]

what about rear doors?

[Satya166]

The rear speakers on both doors and centre speaker on the dash are working

2 possibilities:
1- bad woofer and Twitter
2- bad wiring
you need to remove the door trim and then remove the woofer and do the ohm check with the Multimeter.
Are you familiar with electrical wiring and how to read it?
