Hi there, i just got my MCS with HK sound a few days ago. Couple questions i had after listening to it was:

1: Does the HK sound have a amp and subwoofer built in somewhere in teh car?
2: Can the HK system be listened at pretty loud? I know with some stock car stereos , the speakers blow and or its not good for the system
3: If i want to replace the deck with an aftermarket one, will the rest of the system still work?
4: how many watts is the HK system?
Thanks alot for any help

 

The HK has an amp, and uses the rear 6x9 speakers as woofers - but not really as subwoofers.
The HK limits maximum volume so it should protect its speakers - some owners complain that maximum is not loud enough (especially driving with windows open)
If you want to replace the head unit, you must either also remove/replace the HK amp and speakers, or use an HKenabler
Specs of HK system are hard to find - I've seen 320W claimed before
