will this battery system power a 12 volt 50 watt&times;4 speaker car radio. if so, how long?

Do you mean 4 speakers, each speaker needs 50W power? If yes, then the answer is "No", it can not. If 4 speakers total power need is 50W, then it can do it and will power a 50W audio system for around 2 hours.

Yes, just be sure that the battery has enough charge so you make sure not to ruin the battery. Depending on what you're running, 40 watts may be too small. Also be sure that you use the proper gauge wire for your application.

It should work, its draw is 5 amps with a slight spike when it starts according to my power meter during its run, so for a car battery a constant but relatively low level 5 Amp/60 watt drain, you would need to look at your car starting battery to see if this type of drain is supported, many car starting batteries are designed to provide one powerful burst of current to get your car started, not a long term drain.

If by 4a you mean 4 amp current draw then this 12 amp hour battery could run in for a max of 3 hours. About half that would be more realistic unless the power draw was less with lowered sound levels giving reduced amp needs. I run a ham radio transceiver with mine which pulls about 1.5 amps on listen and 10-12 on transmit. I have used it for over 2 hours of mixed use and it was still going.

Yes it will run off any 12v system with a small battery you wont have as much run time as you would a deep cycle or automotive battery , but I am sure it would last all weekend if thats the only thing running off of it ... run a in line fuse of the red wire " positive " & run it how you would like from there .mine has wire coming off the fuse link so I put a eye style connector of that to the battery post .

Yes, but it's impractical. You'll need to get a power inverter, plug it into the cigarette lighter, and your car needs to be running. You're better off just using NiMH batteries and having two sets of them. This amp will run a LONG time on a set of batteries though. Some people have reported getting as much as 20 hours. -TJ

Sure it would work... but 1.5 Watt panel is not very much input in a car or truck battery. How much amp out put is that panel? Let me know... Don

12v battery that is needed is used to power your head unit. You head unit amplifies the power to each individual speaker output (usually 50w x 4). These speakers will not work without at least a 12v power source.

Short answer: No Long Answer: Watts = Volts x Amps. In this case, it's a battery, so instead of amps we get amp-hours or "Ah" (1000 mAh = 1 Ah). This means that this battery pack is rated to produce 24 watts for 1 hour. In other words: Yes, it would power your motorcycle sound system at 24% volume for only one hour. If you turn the volume up, you get less time. I don't think this is what you are looking for. You will need a much bigger battery. This other battery looks like it would work better for you. It has a 9Ah rating: http://www.amazon.com/Peg-Perego-Battery-Volt-Drop/dp/B00002EQAF/ref=sr_1_1?s=toys-and-games&ie=UTF8&qid=1386217432&sr=1-1&keywords=small+deep+cycle+battery That means that you could power your stereo with it at full volume for a little more than an hour, or at half volume for two hours. Also, don't try to charge this battery from your motorcycle's electrical system. The alternator on your motorcycle is not nearly powerful enough to charge it. This means that you will have to charge this battery after each use of the stereo by plugging it into a charger at your house.

Sorry. I'm not sure. I'm using it for my home alarm system. However, if the specs are similar, in your case, 12V 4.5Ah vs 12V 5.0Ah. It should be OK. The battery is a general purpose battery as long as the connectors meet your requirement. Of course, the battery itself is not water proof, so be careful for outdoor use. - Mike

This will work for most car systems, but not the big monster cables used for for large amps running to the trunk. This is a is an inline power filter used to supply power to your radio only.

This is a 12V battery. If you put 4 of them in series you'd get 48 volts, but that's far from optimal.

It is a 12 volt system for autos or boats. It would work but you would have to use a 12 volt DC converter to power it. A subwoofer with a built in amp that is powered with 110 volts would probably be a better solution.

12 volt is the input voltage. The entire string pulls 30 watts. If I remember correctly each module pulled 1.2 watts. Amperage is wattage divided by voltage. You do the math. Yes you can connect to a car battery

hi there, a normal 12 volt battery or power supply will be just fine. that's the regular power for these units. thanks from Maple Leaf Gps

I don't know. It worked for 5 hours but I had it hooked up to a car amp. The car amp is 550 watts. But it didn't work.

I am assuming that you are talking about using this to power a stereo not in the car? It does have a 12V 4 pin connector. So if the stereo runs on 12V and you can figure out how to make the connections, it should? work.
