80 KG Weight Reduction - Full Audio Delete - Head Unit - Speakers - Amplifier - GRMN Part

So far, I have deleted the following parts from my Toyota GR Yaris, reducing the weight by approx 80 kg:

Engine cover approx 1.5 kg
Battery replaced approx 18 kg
A, B, and C pillars approx 3 kg
Headlining approx 3 kg
Headlining wiring looms with lights, microphones, and alarm senor approx 1.5 kg
Full audio system approx 5 kg
Parcel shelf, boot floor, polystyrene, and tyre pump approx 4 kg
Rear seats approx 30 kg
Rear seatbelts, seat mounting brackets, and all bolts approx 4 kg
Floor mats approx 1.5 kg
Capet approx 3 kg
Carpet sound deadening approx 3 kg
Misilanous trim pieces, brackets, and bolts approx 5 kg

I did weigh everything removed out of interest; however, I did not make notes, so the weights are from memory

As part of this, I deleted the entire audio system, which includes the:

Headunit
Amplifier (under driver's seat)
Front speakers
Rear speakers
Rear speaker steel mounting brackets
Bolts and plastic trim pieces

The total weight saved from the audio deletion is approx 5 kg.

The head unit (including plastic housing, trim, and blots), amplifier (including plastic housing and blots), and front speakers (including bolts) weighed in at 3.6 kg.

I removed the rear speakers months ago, and I cannot remember the weight, but the speaker brackets were steel and quite heavy and, in total, weighed approx 1.5 kg.

The head unit was replaced with the same trim piece used in the Toyota GRMN Yaris; this part fitted perfectly without modification.
