I have 4 speakers, 2 of them are stock. I also have an aftermarket head unit pushing 52w 4 channel. When I listen to music I like to listen to it loud and at some loudness point for each bass hit the voice and everything is a bit distorted. What causes this?

sounds like you don't have a high pass filter. whats happening is the speakers aren't made to reproduce anything under ~80Hz, so when they do play something that low it sounds like trash and is all distorted. Your headunit should have some sort of high pass filter, check the manual.

Your speakers are trying to play frequencies too low for them. HPF like Kangaroux said, add sub to play these frequencies instead, or listen quieter :)

Would switching the stock speakers out with better ones help? I feel its mainly coming from the two stock ones and Im about to switch them out with some better ones

it's not the speakers that are the problem. you're sending low bass to speakers that aren't made to reproduce it. most head units have a high pass filter (or HPF) built in. what headunit do you have?

I found out how to change the hpf. Should I just play around with the settings for it until it sounds right?

set the HPF around 120hz...you don't have the MACH 460 system do you ?

Could you be asking too much from your amp? There's no way that deck is putting out 52x4. It's probably 15x4 on a good day...

Louisiana, no Mach 460 here. And I don't have subs yet so I want as much bass out of my speakers as I can so shouldn't I set it to something lower like 80hz?

These numbers sell decks... those are the max numbers im guessing. the true rms will be less than that.

most decks so like 15x4. 52x4 is a total BS number.

When you keep pushing the speakers as you are you will only cause them harm. If you want lower end then you need purchase a sub/box/amp to get that. The mids/highs are just that and are not meant to reproduce lower hz levels. We are not trying to be harsh or anything, just trying to help you understand why the speakers are distorting and why you won't get what you want out of them.

The 52x4 number is marketing BS, true output (RMS) is likely more around 15x4. You have 6x8s in the rear deck, right? Those should be more than capable of producing pretty decent bass without distorting. I think you're pushing your HU beyond its limits.
