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)

How easy was it to keep the factory amp/sub with the new headunit? Did you splice or use an adapter?

qha_vn

it was quite easy as long as you have access to JVC HU installation manual (comes in package) and wiring diagram of stock HU.

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.

Get this kit, idk if they have it in VN but i'm sure you can get it from the states.
I didn't know that cars in vn can rust ( talking bout the first picture speaker box bracket//bolts were all getting rusted)
