^^ Hmm... mine sounds pretty crappy with the Pioneer HU. Can you hear the sound clearly when you turn up the volume?

 

Different ears are going to be satisfied at different levels, but in my experience, I've never seen a head unit power aftermarket speakers appropriately. Soon as you stick an amp on those, they are going to "crack" as my cousin puts it.

 

the bass on them does distort if you turn it up and sounds like ***, but for highs and mids they do really well i'd say. Then I have my subs for the bass. I turn on the HPF so that I dont have to hear the speakers bass, and it sounds pretty good imo. Though I am no audio expert by any means lol

 

Ideally, you want your fronts to have that HPF on, so they can produce their mids and highs of sound ranges clearly and distort free. You never want to have them produce everything. Then your rears would produce mids, and your subs all bass. No 1 speaker is built to produce the whole sound range without distorting.
