I have a 10 inch 750watt subwoofer and a 600 watt amp in my car and i
played some basstester songs on it and it stopped working today. so i
turned the car off and restarted it and the woofer works but only when
the volume is under 15, i used to play it on 20 and it worked fine. if
i turn it up past 14 the woofer stops working and i have to turn the
car off and restart it. what do you think the problem is? did i blow it?
If you turn the power off and restart, the most logical answer i know of is your amplifier is going bad. I am not sure of the model and brand of your amplifier, but there should be a protection light on the amplifier somewhere that will most likely be on, caused by overloading the amplifier.
You will most likely have to replace the amplifier, or check with the manufacturer to find out if they can repair it or help to further diagnose the problem.

Quick test...with your Lanzar volume all the way down, connect MP3 player or other type audio source directly to the subwoofer input connection. Play audio and slowly increase volume control. If subwoofer is working using this method, reconnect and check for audio output to Lanzer connection problem, or subwoofer "settings" issues with the receiver.
Wow, i just answered a similar question so, pretty much the same answer.......
You seem to be looking for an amp made for car audio. There are many
brands, but I going to give you the specs for your particular speaker
which will help in choosing, not a specific name brand amp, but at least
one with the proper power outputs/requirements.
based on the model number you provided, is rated at 4 ohms .Nominal power
handling range is 300 watts. And a peak of 600watts. That does not
mean start cranking 600 watts thru the speaker, it will blow. I suggest
you acquire a single (mono) channel amp that provides 350-400 watts at 4
ohms. Leaves you a little headroom on the amp, but use caution.
The 600 watt rating is FAKE like most of our advertising and will be either 600 watts PEAK or 600 watts PROGRAM. If it is Peak, use an amplifier with no more than 100 watts a side RMS... If it is program rating use an amp with no more than 150 watts a side RMS but that is pushing it for speaker safety. Also pay attention to the spec of the amp as to what it will output at the impedance of the speakers. I read the spec on the speakers... they are rated 150 watts RMS, NOT 600 watts... Use an amp rated at 150 watts RMS MAXIMUM at 4 ohms per side. Also don't turn up the bass excessively or you be buying new speakers. Twelve inch speakers would be adequate for a 20 by 20 room at SAFE listening levels. If you want driving bass, you need to get an 18 inch subwoofer.
It depends on the box you are installing them in. If you're going for sealed box they you can put 600-800 watts on them as long as you're careful with the gains and bass boost off. In a ported enclosure I wouldn't put more than 600 rms on them and still be careful with the gains. set your filter on your amp to about 80 hertz and match it on your source unit.
