Perhaps you cannot 'see the woods for the trees'! ;)
A chip amp is what you want and you are welcome to start looking here
Then follow the GC web ring and you will have all the information that you need. :att'n: |

My suggestion would be an inverted design using a buffer. Buffer choice is down to what you feel comfortable building, they all sound very good with a GC.
All the designs on my site use the LM3875 but I ahve just built one with an LM3886 that sounds very good too. etails will be posted on DD when I have time.
And don't forget, if you are not happy to build from scratch, there are several people offering PCB's and/or kits. ;) |

| Why you use the LM1875 for 20w and LM3875 for 50 ~ 60w ? |

what should i use for a volume control??? im going to build it in the same case... nothing fancy or expensive.. only going to use 1 input....
im not sure if i should go for the LM3886 or the LM3875. the price is the same.. going to make a amp for a small 6½ inch sub |

Use the LM3886 for a sub, it will give a bit more power.
And if this is for a sub, any pot will do. Try a 20K or 50K log. If you want specific recommendations, then search this forum. ;) |
