Then of course no warranty la...

Wow, suddenly alot of argument about audio system...

My ICE priority is
1. Speaker.
2. HU

sometimes ppl tends to believe HU can enhance the sound,simply because it give user more room to change the sound, such as eq. But in fact if u switch both stock player to default flat setting, both will sound same, at least this apply to entry level aftermarket hu.

Speaker is a component to produce sound, it will determined the most for sound quality.
