Eq problems

[Associated98]

Hi guys, this is my first post so thanks in advance for all your help!

Ok, Im new to the forum, but not to car audio. I know my way around. My current system includes two infinity reference 6012i door speakers, oem deck speakers (car is a 2010 mitsubishi galant), wally world soche power wires running to my alpine mrv-500 amp paired to my craigslist alpine 12in. Type s blue lable. Rest of the wiring is unknown in brand besides the kicker speaker wire. Head unit is an ooold sony explode cdx gt400.

I know my way around eq and have tried to the best of my ability to combat my problem but to no avail.

How can I prevent the awful, ear bleeding screeching from my speakers when Im playing... Say some tool at high volume? I have my high turned down as far as I can with out compromiseing quality, mids are right where they need to be, and my fade is set with a rear bias favoring the rear as it helped with the screeching. I can not afford new speakers, clearly, (although i know new ones of better quality would fix this) and cant afford an external high pass filter. Is there anything else i can do or have I covered everything?

basically you need more tuning power.

Measure out the speakers resistance to see if it's blown

I usually can only stand about 2/3 of total volume due to this noise when listening to music like tool. when listening to rap/trap/more bass orientated music I have no issues with the system. I will note that I have melted my sub twice so I don't push it very far anymore, another reason I only use 2/3. I do not have an amp for my door speakers, nor adjustable gain for the 4ch pre outs (I believe 50 watts x4 is what my head unit provides) I am at some point planning to replace the speakers and head unit but its nice to wish...

There is only 1 headunit that has more then 15 watts a channel.

Sorry for the confusion, I ment 50watts split into 4 channels. Im just used to seeing it like XXwatts x 4.
