Hello, I'm new to the forum and the hobby and have a newb question. I'm building a portable boombox that runs off a 12V SLA. I'm looking for advice on selecting an amp. I have built two before from thrift store speakers using pyle pfa 200 and 300, respectively. Both had problems, the pfa200 had one channel crap out on me shortly after I got it. The 300 has a strange problem with the voltage sensitivity (I'm thinking, still working on it) where it will run off the adapter but not the slightly higher voltage of the SLA.
Anyway, I'm thinking I want to start using these tripath amp boards or maybe someone has some better suggestions.
My question is, what options do I have available. I see these tripath 25wpc ones on ebay for $25 after shipping from china and no name distibuters, are these junk or decent?
When I buy an amp board, how much modification has to be done for a final setup? I've only used out of the box ready amps like the pyle.
Do I need to build an enclosure for the board or just mount it as is.
I'm not really wanting to buy some of the more expensive T-class ready to go amps. I've got more time than money so no learning curve is too steep if it makes for a better and cheaper solution. Thanks, this forum is great and full of so much information, hard to get a grip on it. -Ford
