just upgraded my audio system at very reasonable cost but very good outcome. here is how:
- change stock nak HU to JVC KD-X50 BT
stock nak HU has 4 x 20W max speaker output while this HU produces 4 x 50W max (20W RMS): so double the power
keep rear pioneer door speakers and nak sub amp and sub woofer speaker
- replace front door pioneer speakers with a pair of Alpine-SPS-410-2-way-4-Inch
same diameter, just need a little handy man to fit it into OEM speaker
Sound quality is a world difference. very cost effective option, recommended. hope this helps.
(sorry my car is ls400 1990)

I needed to splice the car wiring to keep stock amp/sub. about 10+ wires needed to be spliced including amp control, signal wires to amp and to door speakers, ant wire, and battery/ ACC wires.
I am not good at wiring but it took me only about 2 hours to get the great sound out from it including soldering the wires together for better quality
i can attache the wiring diagrams here if anyone needs it.
