I know Alpine, Eclipse, pionner-premier are good for HU.

But i have also heard people says that the new Alpine arent as good as the old one, and that Pioneeer HU makes better souding bass then other HU. Are these myths or can One HU sound better then the other HU? Eg. apline HU VS pionner HU

I owned two alpines HU, i i really like them, specially reliability. Never gave me a single problem , like stuck CD in the box, or skipped tracks.

But i am open to opnions and recommendations.Thanks
