Off Grid Music

[Divad]

Im using my Bluetooth speaker in my soon to be solar powered shed but was wanting something a bit better.

Ive got a car stereo but it says that its 100w, 25w per channel x 4. So at low to medium volume do they actually draw 100w?

If i only run 2 speakers would it draw max. 50w?

Whats everyone else using in their solar powered sheds, homes?

Thnanx Dave.

We use guns and guitar's in the Ozarks.

a better Bluetooth speaker might be a better plan.
You would need to measure the ampdraw to know what usage is on the equipment, amp watts are peak rated, hard to guess what a random setup would draw.

jbl portable loudspeaker can be chained up to 100.
fully charged you get 8 hours of music.
you can keep them charged with a small 5V panel.

I just picked up one of those f900s amps. Kinda impressive

13-24v input, built in BT, nice big knob and terminals.

I would be amazed if that uses 100w but a simple current meter will tell you.

I use this $30 car stereo with Bluetooth in my shed and run it off a 12v LiFePO4.

And here is the $30 LiFePO4 battery that runs it:

Thanx for your replies, ive got a better Bluetooth speaker and also have a car radio and some speakers that ill hook up and check the power usage.

Thanx Dave

Car stereos have little need to be energy efficient while bluetooth speakers must be energy efficient. My bet is on your new bluetooth speaker.

Best setup I have found so far is a Bluetooth class D amp est. 25 watt x2 and two Dayton audio transducers on some pink foam insulation. Powering it from 4 18650's in a parallel series configuration @ 16.8v
Transducer
Similar to mine

What is your run time with that setup?

The better Bluetooth speaker thAt i have is charged via a 240v power brick (Australia here) and i would prefer to have the system powered by 12v.

As i already have a 12v head deck i have ordered a pair of these Speakers to give a try.

Apparently they sound pretty good. Here is a long video of their performance. Worlds Best Speakers?

Thanx for replies Dave

I've never really measured it I use it in the garage off and on for weeks before charging. Could play few hours at a time. I also have a G-boom when the original battery died I bought some 18650 holders with 2 ea. at 8v I wired this to it ran the wires to the outside it last a long long while.

I have a 1 watt 12v FM transmitter which has a range of 1/2 mile. I have 3 terabytes of music which runs on shuffle, but it can use a streaming service or anything really for the music source. Then I just use whatever FM radio is available. My Motorola phone can pick up FM, I use that a lot.
