Hello TFiatians, I recently got my Punto Emotion Pk 1.4 Petrol and pretty happy with its performance and features till now. But I simply hate its OEM HU and speakers and would like to change it asap. I am planning to change it after my first service which is due next week. I have checked johnny and Grandeur thread for speaker change but like to know from your experiences which speaker would go well with the stock HU. Also changing speakers void any warranty or not?
