Im not sure if this is the correct place to post this but Im wanting to make a amp to power my speakers. I have 2 Infinity Reference 2000.1 speakers that have a max of 100w power and some subs. I was thinking of getting 2 of these amps , one for left one for right to power my speakers and subs but I wasnt sure if it would work. I also did know how to power it. Does anyone have any suggestions on what to do to make a stereo 100w amp that has a volume control, a bass and treble control would be nice to.
Thanks Chris
Thanks Chris
It sounds to me like you are looking for a standard, integrated stereo amplifier that has pre-out connectors to also feed a sub-woofer. 'Pretty standard retail product for the last 40 years, I'd reckon.
To DIY this is a matter of combining any suitable amplifier, preamplifier and tone control circuits found in the corresponding forums here but you won't often find them all together in a single project. The demand to DIY this is not great since retail products at very low cost (free on the curbside even!) are everywhere. The big issue is construction and parts quality which really make such a project a labour of love and use up a great deal of time and money when sourced individually.
Perhaps it would be better to start with an old but working amplifier and work through the sections, upgrading them as you decide and learning from the various threads here what you need to do this and why it may be necessary. It's a long road to success there and without a complete kit and design, it's near impossible so do try this option first, as many here have done.

What Ian said.
Although, if you want to run a subwoofer, few if any integrated amps or stereo receivers have line level outputs AFTER the volume control which are suitable for feeding a subwoofer. Perhaps a better choice is a more recent AV receiver, since those have a built-in subwoofer crossover and line-level output. Thanks to HDMI, Dolby Digital receivers have been showing up in thrift stores lately, as cheap as $20 (although that one was missing the remote).
If you want a lower powered, very compact amplifier that can run from 12V efficiently enough to run from batteries, search eBay for TA2024 amplifiers. From under $10 (shipped) for a board that's ready to go. $20 to $30 for one in a shiny case. They're about 10 real RMS watts into 4 ohms, which may not sound like much, but that's the same as a "high power" car head unit. Ideal for small sound systems (bedroom, kitchen), computer speakers, DIY portable boom boxes.
