Hi All the sifu, need to ask you all some advice. I understand that (national car less then 40k) stock HU and speaker need to be replace if you want to have an improvement. The question now is that if i only have budget less than 1k. Should i change the HU first or the speaker first. I went to a few shop and 2 shop advice me to change the speaker first and one shop advice me to change the HU first.
Change speaker reason was because the original / come together speaker only are (low amp/watts, not sure what they said) speaker. So once you change speaker you will see a different.
Change HU reason was coz the stock HU is in output so even you change the speaker you would not really see the big improvement . Is best you change he HU first, you can see the different that way.
I am currently using the FM radio transmitters thing for USB song. Don't really have CD in my car. Either radio or MP3 using the FM transmitter.
Please advise.

Of course, change the HU first, the highest spec as you can. If you want a significant improvement, find HU with at least 4-ch pre-out, if you are seriously into audio, go for at least 3-way active. Some of the forumner here sell decent HU, mine bought from them 4 yrs ago and still doing fine, Pioneer P7150UB.
Later put on an amp, but please dont buy cap ayam brand, better find 2nd unit of well known brand amp rather than new cap ayam. 30W rms is enough for front staging. Forget those rear speaker.
Later change your front speaker will a good component. Again no ayam brand.
Last digital amp with well known brand sub. Again no ayam brand.
I've experience both a bunch of ayam brand component with a few well known branded component. The same cost of investment, but a different world of experience.
Goodluck in your ICE journey
