Default TDA2030A Power Amplifier

Recently I've built a TDA 2030A power amplifier. The sound quality is very good, solid bass, good mid and good high. But I'm facing a problem, it can't go loud enough. When I try to turn up the volume, the sound get distorted. Maybe the power isn't enough. Does anyone has an idea how to make it more powerful, other than bridge?

Well, the TDA2030A seems to deliver 18W in 4ohm, so if your speakers are not very sensitive I guess you'll have to DIY yourself a more powerful amp. (Other than bridging )

Apart from a gainclone you might consider a nice classA amp like the ones build over at the Passlabs forum.

Are you running a single or split supply? I have built a single supply TDA2030 amplifier module. I noticed that at +12V and lower supply voltage the module distorted if I turned the volume up. At higher voltages the amp was sounding nice even at high volumes!

I used split voltage and use a transformer with 12v-0v-12v, when it converted to DC, it becoming +16v - 0v - -16v. Is it enough for TDA2030A?

Btw, does any I.C with more power than the TDA2030A, I mean I.C with five pins like the TDA 2030A?

A guy on a french forum just said the same. The TAD2030 is one of the best IC power amps. Event better than the 3880. Just lacking a bit of power.

The lm1875 has the same pinout as the 2030A. And it can handle +-30 volts into an 8ohm load, compared to +-22 for the 2030A. Won't give you much more power but it would be easy to swap in to compare.

I have seen circuits that utilise 2030 and the output power is helped with two power transistors, class B but the chip supplies the oomph at low volume settings, something like this http://www.kemo-electronic.com/pdf/b086/b086.pdf

But dunno if it ruins sound quality and maybe it is just better use 3886 or 3785, or more efficient speaker. Maybe you could add a subwoofer with powerful amp to your system and get some stress off the mains speakers and more total loudness

You can always use it like audio driver with power transistors for more power.

I built a 2-channel amp with TDA2030. It was a bit unstable and would oscillate but only with heavy loads or high volume. It sounded very, very bad. Rerouting the wiring fixed it.

Have you built it on a PCB or did you use wires? Any photos?
