Can I bridge TDA7388

[diy1995]

Hello,
Do anyone know if I can bridge TDA7388 4 x 45w amplifier?
I know that some 4 channel amplifiers are bridgable, but they have different pin layout (multiwatt15), TDA7388 has flexiwatt25.
But I can`t find a schematic for bridged mode -if possible?

Here is the datasheet.

Thank you!

Hello.
Almost all car audio amplifier are already bridged.
This amp is already bridged, so you cannot.
You can use TDA7560, it's more powerfull and accept 2 ohms.
Also,you can use step up converter power supply for 18V instead 12V.

Ok, thank you for anwser.

I have smps from car amplifier. It has 2 x 25A fuses so... 2 x 25A x 14V = 700W (I know that this is not 100% accurate, let`s say 500w to be safe 🙂).
It has 27-0-27 output (so it`s positive and negative supply), this was measured with 12V input.
What are the ICs that would give me the most power on 27-0-27 supply at 4ohm load, mono?

I would like to build car subwoofer amplifier so high THD is not a problem.
I am searching myself, but didn`t find anything good sofar, because most of powerful ICs are using higher supply voltages... I`m aiming for about 200rms @4ohm is possible...?
