What is the battery life of 12V Bluetooth speakers?
How can I install Bluetooth speakers in an older car without built-in Bluetooth?
Installing Bluetooth speakers in an older car without built-in Bluetooth can be done by:
- Using a Bluetooth adapter: Connect a Bluetooth receiver to your car's existing stereo system via AUX or RCA inputs.
- Replacing the stereo head unit: Upgrade to a Bluetooth-enabled car stereo that supports wireless audio streaming.
- Installing a Bluetooth speaker system: Some systems come with built-in amplifiers and speakers designed for vehicles like ATVs and cars, which can be mounted and wired directly.
Each option varies in complexity and cost, so consider your comfort with installation or seek professional help for best results.
What are the best ways to connect my phone to car Bluetooth speakers?
Connecting your phone to Bluetooth speakers in your car or ATV typically involves these steps:
- Turn on the Bluetooth speaker system and enable pairing mode, usually indicated by a flashing light.
- On your phone, open Bluetooth settings and search for available devices.
- Select the speaker system from the list of devices to pair.
- Once connected, you can play music or take calls through the speaker.
Some systems also support AUX or TF card inputs for alternative connections. Remember to keep your phone within range and ensure the speaker is charged or powered for uninterrupted use.
Hello All,
I have an old 90s Volvo double din radio that I want to add a cheapy Bluetooth module. I have brought this cheapy 12v module.

I haven't been able to find any schematics but some old posts on where to solder under the Mainboard to hijack the tapedeck audio channels.

I am taking power from the ACC connector and ground from the audio board as shown in the pictures.
At the moment it works but only the right channel. If I select left there is a high pitched humming(?) noise. I tried to show as much of the setup as possible.
Thoughts? I am wondering if it's my rubbish soldering or taking the wrong ground from the power board?
Thanks in advance
Hi y'all
As always, right after the Burn I get excited about another project I can tinker on in advance of next year's burn.
This year, I want to build a mobile sound system ... a sort of speaker box. I have done some prelim research and decided to make it a 12V system running off of a deep cycle battery. I've also decided to power it with a car audio amp (d class) with 1 12" sub or 2 x 10" subs cut into the box. Some reference projects I've looked at for inspiration:

My INDECISION 2000 moment right now (for those old enough to remember the reference lol), is the source of highs and mids. These are the options I'm considering:
-
A tweeter horn and a mid horn like the Trailer Mounted Bike System
-
A set of car audio or marine speakers cut into the box, like in the Other Projects examples. The marine speakers also come in their own cone-shaped enclosures, which might improve sound quality.
-
Two small PA speakers rewired for 12V (Step 11 of this EPIC project description https://www.instructables.com/Battery-Powered-Mobile-Party-Sound-Systems/)
-
Two to four small outdoor speakers in their enclosures, wired to the car amp
Anyone have any thoughts? As always with these type of projects, the goal is to have the loudest sound to balance the subwoofer bass output, at the lowest power cost with the best quality of sound. I don't know enough about the difference that native enclosures make (if I use enclosed outdoor or marine speakers, or re-wired PA speakers) but assume if I go with re-wired PA speakers they will be louder (albeit draw more power) because they have decent woofers with heavier magnets and more substantial construction).
Would love anyones thoughts on the matter, I have hit a wall with my research and don't want to make an uninformed decision before I start purchasing components!
