Not a world of difference, no. Amp can be internal or you can use an external pro amp.
But, I would probably want to use a subwoofer that is higher in sensitivity...?
I think maybe down the line im gunna have to experiment with DIY home sub...
Me and some friends actually hooked up 3 car subs in a house to my older denon 1603. That was a fun experiment. 1 car battery and a 25amp charger... 3000watts ish...

OK, but nothing special.
