JBL premium audio upgrade

So I’m about to put a hertz 5 channel amp with 2 JL Audio 10in subwoofers in the stealth box. Just curious but the guy who is doing the install is planning to hook up all the stock door speakers up to the hertz amp as well . My question is will the JBL door speakers sound better and louder hooked up to the amp???

 

They'll sound good as best as crappy speakers can sound.

 

Yeah I see your point. It’s quite disappointing that the system in there sucks as bad as it does

 

Might as well throw some components in there while your at it

 

Depends on how much of an audiophile you are, some people are happy with just amplifying the JBL speakers. If you are running wires to everything you may as well upgrade the speakers IMO

 

At this point I will do anything to increase the volume and increase the bass . anything will sound better than the stock system . I think I’m going to go all out and replace everything
