there is a point where my volume reaches that all the levels seem to blend together, i cans till hear everything fine but it all sounds liek one wavelength, im not sure but i tihnk it might be the threshold of ear damage

Depends.. if 4x150 watts is all you have, no, if there is more, then it'* possible. I'l planning a 2,900 watt system.. that could cause some damage. Here'* what you have to watch out. Listening to loud music isn't bad, listening to loud music for a long period of time is. Your ears adjust to the volume, and once that happens, you start loosing your hearing. If you turn down the music for a day or two, and keep it at 25% volume [approx, this all varies by system], your ears will adjust and in a few days that will seem fairly loud. If you slowly work your way up to 40%, then that will seem loud, but you want louder, and it just escalades. You will want to keep it down the majority of the time, but don't stop listening to loud music, by any means. Unless its rap, then keep it down 100% of the time.

When your music starts to blend together like that, its a sure sign of distortion. It can be caused by a few things but i think the most likely 2 would be either reflections or your amp cliping. IF its your amp cliping, then just buy new one but if its reflections, youll need a crash course on physics. start here. www.elitecaraudio.com

it wasnt distortion everything sounded perfectly clear just in a monotone way

130db is the threshold of you ears hurting, 160 db is the threshold of instant hearing loss. Listening to your stereo won't make you go deaf....right away. If you listen like this for extended periods of time often, then be perpared to start looking for hearing aids. Im not sure what you are describing, if the sound is still clear? Does it sound good or bad when it blends together?

obviously hard to describe but it sounds kinda like one those old handheld radios that dont have extremely high or low levels, except alot clearer, like i can hear it all perfectly clear, and i can still hear the highs and lows but they all seems to closer together in some middle ground

No matter how many watts your puttng out, you can only hear so much of the low frequencies before they sound the same at any higher level of volume. You can only feel the difference.

That sounds like your system is running out of juice at those high levels. Amplifiers are often rated at midrange frequencies besause they can reproduce those frequencies louder than highs and lows. TURN IT DOWN!!! you are probably distorting the crap out of it You may want to look at getting a more powerful seperate amp to run your speakers.

i agree phoenix sounds like he might be experienceing some clipping....

but to answer the original question, yes, 4x150 watt speakers can make you deaf. it'* not the wattage it'* how loud it is. You can have a 20 watt tweeter that can still make you deaf.
