Summer Project - Make an INSANELY LOUD Bluetooth Amplifier!

  • Опубликовано:  2 года назад
  • Here's the amp we'll be using Amazon:
    eBay (ships globally):

    Amazon UK:

    In this video we'll be making a wireless bluetooth-enabled amplifier so that we can put old bookshelf speakers to good use!
    Not only is the sound quality fantastic, but it can also go super loud! It's also quite easy to build, and doesn't require any special tools - you can get away with just a hammer, nail, and a screwdriver if needed. Seriously!

    Full parts list (includes international purchasing links):

    Happy building!

    Oh, by the way, here's the note about the little switches:

    These switches change the gain mode of the amp. If they're both on, the amp can reach insane(er) volume levels. However, to hit these volume levels without distortion, the amp needs 25v, which is more than our batteries can provide. The amp is loud enough with them off, and it also means that the signal to noise ratio is MUCH improved, so I don't really recommend messing with them.

      Awesome video. I see the one you use is 25W, will the 50W one work the same?

    TRAFO COMCHAN День назад

    To be clear this is a 25w per channel amplifier so it may seem it's 50w each speaker (which would be a 100w stereo amp) so it's still a good amplifier it's only 25 per channel just to clarify things still good video

    So I am wanting to make a Bluetooth speaker using the TDA7492 50 W + 50 W dual BTL class-D amplifier and a some automotive 2 way speakers. I also have 7 samsung icr18650-30a batteries that are 3.7v in series that's 25.9v and 19,000mah. So my question is what wall power adapter should I use to power and recharge the system? Also what would be the rough battery run time?

    Why didn't you do this project with a rechargeable battery, so it can be charged without removing batteries?

    I built this to work with high end Sharp speakers with low impedance. I will admit this amplifier can drive just about any set of speakers I own (a wide variety of different watt and impedance levels). But in order to drive the 3 other gain switches, let alone the default max volume, you need a much more reliable and constant power source. I wanted to do this project for sake of affordability, utility, and customization; but alas, I may have to spend quite a bit more money on a better battery system in order to use this to its fullest potential. It was never intended to run off of battery power. Cheapo dollar store AAs will definitely not cut it for this project the result of using such will cause the batteries to actually overheat and eventually swell and release an excess of battery acid everywhere. I'm not claiming that this video is falsely representing the capabilities of this amplifier, but you definitely need to pick an extremely reliable power source that can maintain higher voltages up to 24v and a longer lasting more consistent mAh rating. My battery setup contained a chain of 16 1.5v AA batteries in a 4x4 grid (using two 2x4 housing units).

    Just a tip here to drill less holes and make the "package" look even better: you can use thin double sided tape to attach the battery boxes to the base plate. BTW I am very, very impressed with this amplifier.

    And the startup sound is suuuper annoying, as well as the vol up down sounds. Is it possible to disable them?

Heres is the thing The speakers i have are two 10watt speakers and one 20watt speaker, and after watching your video and following through description I found out that you used 2x25watt amplifier. The question is can i use the same amplifier with all my speakers or do I need to get higher amplifier or 2x50watt amplifier. Can you tell me which amplifier to use for all of these speakers? And how many batteries, and what type of batteries do I need to use in order to power up whole thing? Thank you.
