Yes, there is. I just replaced my front speakers with Sony XS-GTF 1639 6.5''. I love the sound, bass is weaker than stock speaker but the sound clarity blows me away. I think just change front speaker will do and keep the back speaker for bass support. You can find the speaker for RM98 at Shopee. They cut open the wiring without removing the original connector and join it with the cable provided by the Sony speaker.

Now that I don't have to pump up the volume so much when driving fast since the sound clarity help to cover up the road noise.

I got mine from shop33:
Cabin filter(carbon) - RM16
Engine air filter - RM19

For Bezza 1.3.

IMO, it's just a filter and aftermarket ones should do the job.

OK. I can try to record the sound coming out of Sony & stock speaker.

Hi guys, I've recorded the audio from my Bezza stock speaker (behind) & Sony XS-GT1638F (front) to compare the sound quality.
