If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.
Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.
You might have blown the speaker. This happens when you play things too loudly and you ruin the speaker inside. You can test this by playing something with a decent amount of bass and turned up a bit. If you hear like a "rattle" in the sound or like something isn't right in the heavy bass notes, then you definitely blew the speaker out. This isn't a tragedy. They're fixable if you bring them to a place that repairs speakers. But I would definitely test it first by hooking it up and playing a loud song with a lot of bass. Hope that helps a little!

hi, Do one thing set the control behind the sub. set the level and cutoff control at it half position. Set phase control at "0" position. Then test the sound. if you ate using tower speaker as front speaker then you have to set the position of phase control 180 , ok
if your computer came with a motherboard disc the sound drivers could be on it you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling a yellow? question mark means you need to install/update driver to do this right click to install driver also click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have the correct settingsthere also click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar if his does not fix the problem
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) hope this helps
Sounds like you have the ground and live possibly the other way around from the head unit to the speakers. The reason for you hearing it from both the tweeter and the speaker is that the tweeter is connected in parallel to the speaker. Swap the wiring and try it.
Protected in short means that the amp is no longer powering the speakers due to one of the following:
1. Volume is up too loud
2. Equipment Failure
3. Dirty power
Turn amp on by pressing the function button on the remote of a source that has nothing on it or is not powered on. If it still says PROTECTED even though you are on a source with no sound coming in, then the equipment is in need of repair. If it simply comes on normal displaying the source turn the volume down till it says MIN. Find the range of your speaker and amp power by selecting a source with music or movie audio and slowly turn it up till either its too loud or says protected. Be sure to double check all speakers and wires to ensure wire integrity as well as proper connection.
You haven't given much to go on here but I'll take a guess. Sounds like you're saying you have no sound from websites when using your browser, but can hear sound from other sources (mp3s, videos, etc. on your computer). Assuming you are using Windows Vista, open your browser (Internet explorer, Firefox, Opera, Chrome...whatever you use to get onto the internet) then right click on the volume icon in the taskbar (on the bottom right of the screen, next to the clock) and select "Open Volume Mixer". This will show you the programs that are running and how loud their volume will play. Find your browser in this list and turn up the volume by moving the little slider below it (up=loud, down=quiet). Hope this helps.
