Another Update: Amp completed for the most part. Been running for 3 days now and I'm absolutely addicted to the sound. The station: Amp: I'm going to run it for another 2 or 3 days, then pull it out, shrink tube and organize the rest of the wiring, polish the enclosure and...

New Update... Haven't had much time to work on the amp lately, but there's a lot of progress since last post. I was able to build and test one channel, play around with some numbers and components to get the best possible sound so here are the pics of how it currently sits... Aluminum Case...

^Sure is, I got one channel to work today, sounds really good. I threw the right channel together just for testing purposes with the minimum amount of components. Moving onto adding all the coupling capacitors along with filters and getting everything ready to go into an enclosure. For now I...

^^ Agree, I picked up some pretty nice aluminum enclosures for $5, will post that later once the individual amp channels are finished. Little Update: I got the power supply completed and working, hand matching resistors one rail completed both rails completed...

double post, mods please delete

A little update on the progress, received all the amp and power supply parts, still waiting on the transformer. A few things still left to pick up locally, enclosure, jacks, connectors, etc. Everything should be in by this weekend so I can post some build pics. Some amp/psu parts I...

Well according to the sound card it's 3v RMS on the output Auzentech, Inc. X-Fi Forte PCI-Express Soundcard : World First soundcards for Music, HTPC, and Gaming Input level on the amp says 1v max on the data sheet. You're right though the higher the voltage on the source it gets multiplied...

Yeah man I think you should definitely give it a shot, at least buy a chip amp kit that comes with everything you need for your first build. I just got my AS in electronics engineering with a pretty good understanding on how amps work and how to put one together. But for specific sound quality...

Operandi, you're the man, thanks for all the helpful info. Polks are probably going to be kept for garage or something just because I picked them up so cheap. Sending them back and taking a 15% restocking fee will make it a pointless return. I'll get around $65 back, is that even worth returning...

^^ I'll be posting my progress up soon, I'm sure this would have been a much more interesting thread if I started it with my progress. Had to make some choices prior, so hopefully soon I can piece everything together and have some sound once again!

I don't think I want to mess with car stuff in the house, rather try to sell it. I'm set on buying a Dayton sub, enclosure and plate amp. Can't decide between the 8" or the 10" HF series. It will be mostly used for games and music, never movies. I'm also thinking of returning the Polks and...

^^ Sold Logitech for $80 today. So I kept the Polks bookshelf for now and while waiting on the custom amp parts I need to figure out one last thing. What do you guys think I should do about the sub? I have a JL w3v2 car sub/box laying around, that maybe overkill for a 2.1 pc system. I can...

Merry Christmas everyone! This morning I ripped apart the Logitech sub/amp. Snapped some pics: Full amp and power supply view 4 chip amps they used (not sure what specific ones yet) Transformer (not sure which exact one yet) Power supply capacitors veiw Overall...

I'm not sure how the software will work being setup that way. Auzentech Forte X-Fi comes with the same control panel as what comes with a Creative X-Fi (whatever the highest gaming card is) If that sounds familiar I may be overlooking something. The only thing I've found is a bass gain option...

LUCIDD, great post man!! I would like to see pics of your above mentioned builds, of course if you don't mind. Also a few other things, first I want to figure out if this setup will work My sound card has the following analog I/Os and is setup as follows: Microphone Input - mic connected...

Haha I know about the amp being overkill, but it's better to build a good one once that would also work for other speakers in the future. The Polks even running off the Logitech amp sound incredible, night and day difference from the stock satellites. What I'll do is build the custom amp...

Thinking about building this amp PA100 DIY 2x LM3886 in parallel gainclone audio amplifier I really don't have time to build speakers now, I will eventually, the polks were super cheap and can always be used for garage speakers or whatever. If I build the amp for now, I can always build a...

Hey guys I'm new to this forum, been browsing around and seems like there's some good info and people on here. With my new computer build and a recent sound card upgrade I've become somewhat addicted to proper sound. I listen to all kinds of music and do some online fps gaming. For a while...
