Question about Alpine PDX-1.1000 1000W x 1 Car Amplifier Car Audio Amplifier

Open Question

I was playing tunes while driving to work then all of a sudden it shut off. I checked the amp and the red light was on the right side of the amp. I unplugged it and the red light turned blue. Everything seems fine. My amp powers on, both blue lights are on, all fuses are fine but now sound is going to the sub.

Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

well you would have to look into the ohms of the amp compared to the ohms of the speaker. If the ohms are different you would have to hook them up in a different way. check the RMS on the speaker as well as the amp, this can also be sufficed by wiring it different if ohms match up properly! Hope this helps you out and if this is not the case let me know.

SOURCE: red light on PDX 1.600 alpine amp... no sound

Hello zim69zim69zi,

Solid red indicates 4 possible conditions: 1) Short circuit, 2) Current too high, 3) Voltage too high, or 4) Overheated. The most common faults are the short and overheated.

If the fault is intermittent, the amp is probably overheating. If it is a constant fault, anytime the amp is powered up, then I'd recommend that you first check all of the wiring. If the wiring is OK, then you have a voltage or current problem. If it's voltage, the vehicle electrical system is probably causing it. You can check that with a meter. It should be from about 12VDC with the engine off, to about 15VDC with the engine running (alternator putting out). The amp should be able to operate OK up to about 16VDC but as components age, their values change. I'd look for a minimum of 10.8VDC and a maximum of 14.8VDC.

If the problem is overcurrent, the amp itself probably has a defective component causing it to draw too much current. It needs professional repair.

Hope this helps.

Rockford Fosgate P3002 stopped working


push down and up on your subs and see if they make a starching noise, if they do then they are blown. take a test light to the amp, on the power and the remote and see if it lights up. if it does then turn the amp down and with a small speaker plug it in to the speaker outs on the amp and see if it plays if not then your amp is bad.

While driving it works good till i come to a stop sign or red light, then it will sometimes shut off, also when turning the corner at slow speeds. but it will fire right up when i restart the car


When was last tune up? Plugs, wires, cap, rotor, all fluids & filters especially fuel filter? I would start there and run a good fuel system cleaner through it & avoid cheap gas.

My ps3 wont power up


try powering the system up by HOLDING the on;off button , it will reset all your audio and video settings . then plug the system using the AV cables (default) .

else, you should take it to an assastance centre for hardware issues checking . can be a problem with your RAM or GPU units that makes the system unable to startup it's firmware .

Acer Aspire cd/dvd/rw drive 'missing'


Go to device manager and look for the dvd/cd on the list. Click on the "+" sign and you may have a yellow, red or black symbol. right-click on the device and reinstall the driver. That should get it working again. If not then try the troubleshooting in the device manager, same place you reinstall the driver. Follow the instructions. If none of that works then it needs to be replaced.

Pls rate this solution.

PS3 wont work


How long were you playing it? if you were playing for a couple of hours, then it could of just overheated, in which case the ps3 will shut itself off suddenly to keep from damaging something. It should work after about half an hour, adequate time for it to cool down, if not, then you might of damaged something.

Problem


Start removing wires from the amp, one by one (except for the +12V, Ground, and remote) until the amp seems to work fine. Usually, this type of issue is due to a speaker wire shorting to something it shouldn't be touching. Check the "non-amp" end of all the wiring to make sure they are solid and correct.

Powers on but no sound


Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
