New heat sink

 

We upgrade cooling system, added 8 fans on the rear panel. Enhance the heat dissipation capability of the amplifier.
 

Capacitor Upgrade

The old one is 3300UF 200V and now the new is 3600UF 200V. Totally add more 300UF capacity. The amplifier power supply board is better than before, it will make your subwoofer bass sound quality more loud and powerful.
