I keep blowing out speakers in my car. And when I put a high pass filter on them the just dont give enough sound. They produce such a low volume that i need to turn the stereo up full and put all sound into that one speaker.. HELP!!!!

I'm gonna hazard a guess and say something's ****ed.
Not much more anyone can tell you until you include some basic details. What car, what speakers, what amps, what head deck, how was it wired, who wired it, all other symptoms.
Plus, something like this belongs in the Car Audio sub forum. Welcome to AMC.

oh my bad. sorry new to the forum. am i able to move this thread? Its a TR magna S/Wagon fusion speakers wired to xplode headunit. I ran them off the amps and they blew originally so i got new ones and put them onto the head. it was all wired properly and i wired it myself but showed a custom audio shop if i had done it right and they said yes (trying to get a job in car audio). On the crossovers the woofers blew. The other speakers are Roof mounted (stock holes) 6.5" fusion

I had the same problem with a Sony head unit. Turned out the previous owner of the car had wired some of the speakers incorrectly. If you mix up the wiring you get a signal which is the difference between 2 stereo channels, you get a lot of DC into the speakers and weak output, The HU overloads and cuts out, or the speaker overheats and goes open circuit. The easy way is to use a multimeter and check for DC at the speakers. Check your wiring carefully if you have lots of DC, go to the Sony website and get the colour codes for the wiring on the HU. If that is OK, use the multimeter to check for short circuits in the wiring and the speakers. Get the basics right before you add amps and crossovers. Good luck.

Don't see why your trying to run your speakers in high pass anyways
Keep them in low and tune from there, running aftermarket speakers off any h/u isnt that great really
Most h/u wont have enough power to run the speakers well
You said you had a amp? then went back to the h/u? I cant see why you would be going backwards for
If its all tuned right then you shouldnt have any problems at all, cant really wire a speaker wrong but only by getting the paraellites? (I think thats spelt right) around the wrong way, could try just swapping the input into the crossover for the spits or input on speakers

If you keep blowing speakers, how many speakers have you been through, if its 2 or three pairs, the problem is most likely with the head unit or wiring. Can you test the speakers on another source. i.e. a small mini Hifi. Go easy with the volume though. A quick test will tell you if your speakers are OK.
Do you have a Woofer, if you dont, get rid of those High pass filters.
Check the speaker wiring for breaks. and check the earth on your Headunit. Bad earths sometimes create a lot of heat in the power source.
I had a drama with speaker output once, and asked a cash converters if I could borrow a Headunit with the same connector, since the wiring was already done and was now plug and play, they had no drama's with that.
I told em if my H/unit was faulty, I'd buy it. So test it with one and tell em it didnt fix it, if you want to give it back to them.
Generally spending a lot of money on car speakers, will get you a set that should be ran of an amp, and most of the brands entry speaker, is designed for H/U power.
Under powering a speaker will shorten a speakers life, but usually not instantly. As a speaker needs to move properly to create air movement over the voice coil to keep it cool.
With your splits, did the woofer blow or the cross-over?
As always with these types of threads, current setup, model numbers, and previous setups that have failed always Helps. Narrow it down a bit. We don't even know if your H/Unit setting are correct.
If your are really stumped, a good audio guy should be able find your problem within an hour, an maybe charge you 60-80 bucks, which you've wasted already.
But if you put up a Hands On - Help me plea, you might just get that help from an SA member for a case of Beer.

Something is just not right here.. The XPLOD Head units pack a pretty mean punch for a head unit.
As SH00T has said
I would be having a look at the wiring.. There is just something not right..
Possibly a Terminal is earthing out on metal somewhere, so remove the Speakers and check for space around terminals, They may not be installed correctly and if they have any gaps around the Speaker then the Back Pressure is escaping dropping the speakers power handling ability.., Insulation could have worn off by the cable being pinched or rubbed some where. There is a WHOLE lot of possible reasons.
It may be as simple as the Headunit settings being incorrect and producing a Clipped signal causing DC current and roasting your coils?
Getting us as much Information as you can will help us out..
Pics of how the speakers are installed can be helpful
If you can, Get us a Vid of the sound your hearing, this can help us trouble shoot the system further...
(Not a Phone Vid but a decent Quality Vid Showing your Head unit Settings and Volume Level)
