A bit of advice to anyone using this Bluetooth board, the volume starts mid range when powering on so you need to access the volume buttons on the board to turn it up or you won't get the best sound. I just put screws through my box to hit the buttons.
I am considering buying the TDA4792P Bluetooth board. I have a 4 ohm speaker that has an RMS of 30Watts and Peak Power Handling of 60Watts so should I buy the 2x50W version or the 2x25W version as it says 'best at 8 ohms'. Does that mean it will be 2x100W at 4 ohms? Please help. It would be appreciated. : )
Mick Bradford late reply but for anyone else wondering the same, in my opinion I wouldn't because it'll likely leave small holes for sound to escape and you'll have your device on you anyway so easy to change on that
I am about to build my own portable bluetooth speaker and might need some help. I have got 1 speaker cabinet (with speakers) [Poineer S-p370): - Music Power [DIN] 50W - Puissance Musicale [DIN] 50W - Impedance 6 ohm. I was going to buy the TDA7492P 50W+50W (red one) and hook my speaker up to one of the 2 channels. I am trying to power this system with 4X Vander 18650 Akku 6000mAh Rechargeable Li-ion Battery (14,8 Volts in total). As I am not familiar with speakers and technical stuff like you, I was interested in your and others opinion if this is a good idea... :D?
you can use a 5 amp adapter for better power and the required amp is 2 amps min but use 5 amps it works best and use the formula power equals to current times voltage to create your boombox
