Battery powered Car Speakers

I want to design amplifiers for my unused car speakers. I have 100W sony Xpload speakers.I want to provide power from a preferably small sized,light weight rechargeable battery. It will be better if i can add two separate amplifiers for both speakers I have.

Your problem would be in doing this ,is that the battery you want to use may not have enough amperage to drive the amps as they do draw a lot of current

It has stopped workin and the red light is flashing.Is this a code and if so how do you read it


The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

Power/protector light changed from green to red and my speakers will not play


does it do it with the speakers disconected? if not you got a dodgy speaker,
if speakers ok and all wiring is correct then its an internal fault most likely

Amp blowing speakers on one side


Either the speakers are old, or you need new ones. If you put new ones and it blew them again, then check the power rating, and make sure it is wired properly. if it is wired properly, then make sure the speakers are designed to handle the power of the amp> :) any other q's ... just ask me:)

Amp overheating


wire size depends on source, not load capability. your amp can provide 500 watts, so gage should be about 8, provided your speakers are 2 ohms each... you can measure them with ohmmeter. If you have 4 or 8 ohm speakers, you should get impedance matching transformers. Also, you should use a supply capacitor on power feed to amp of about 10 Farads...these are large and not cheap, but they provide "backup" power for heavy bass loads.
