| The 22 watt amp is easy to build, and very inexpensive. The circuit can be used as a booster in a car audio system, an amp for satellite speakers in a surround sound or home theater system, or as an amp for computer speakers. The circuit is quite compact and uses only about 60 watts. The circuit is not mine, it came from Popular Electronics. |

| I just took this camping, we were running it off a 32 amp hour battery with 2x15 watt solar panels. This amp only drew 1 amp of power! We played music all night and all day, even with the music going the batteries charged back to full. Very impressive. (Editor's notes: Of course, 1A at 12V is only 12W. So run a lower impedance speaker to get closer to 20. Or a higher supply voltage.) |

| This works better than I expected! | ||
| If anyone is looking for a PCB layout for this, I have one. Email me if you would like a coppy. | ||
| How are the pins numbered on the tda1554??? Other people have already asked this but i did see a reply, and have searched EVERYWHERE on the google machine and can't find the answer. | ||
| How can i insert a volume control in this cct ? | ||
| yes ,this circuit works for any type means any ohmic speakers | ||
| Works Like a charm. i even put in a power on/off switch, and a cooling fan, and integrated it all into a housing. The finished circuit is about 3" x 4". Well mine atleast. | ||
| Haha it really does work, and it really does sound very good. i didnt have any perf board or anything, i just soldered the components together on a piece of pcb ( no traces ) and smothered it in epoxy. driving 4 8 ohm speakers... TOO LOUD and it doesn't distort. | ||
| Hi! i wonder if its 22w/ch or its just 11w/ch. But anyway, i am more interested in building a hi power bridgeable audio amp. Can u feature a ckt disgram of a 200w bridge transistor amp? Thanks a lot! | ||
| I made this circuit to power my mp3 speakers in my car and it works! My only problem is that when I turn up my mp3 player above 3/4 volume it starts to cut out. I have a great heat sink and know that is not the problem. I am using a TDA1554Q chip. Any advice to improve on this? | ||
