Greetings all, this is my first post and I'm looking for some help because I'm feeling a bit overwhelmed! Here's what I'm trying to accomplish:
I am needing to build (or buy actually, but I like the thought of building one) an amp that can take audio in from a computer's headphone jack (so 3.5mm plug) and then feed that out to two speakers (a pair of Dayton Audio 60W max / 30w RMS 8ohm 90hz-20kh 91db sensitivity) *and* have an output I can send to the RCA input(s) (Line In) of a Polk 10" powered subwoofer.
The purpose of these is to drive the audio on a homemade pinball machine (that's the reason for the powered sub--subwoofers mounted into the bottom of pinball cabinets just don't sound that great). I purchased one of those cheap Lepai amps and it sounded like crap and the subwoofer deal (connected via speaker wire) sounded terrible.
So I don't think I need "world class" sound (and I'd like to keep the thing small and inexpensive) but I have recently gotten into electronics and I find that I really enjoy building and soldering together kits. So I thought I might come here and possibly find a kit, or some instructions/tutorials, on building something like this? or is there some other cheap option I can buy that might suit me better for this task?
I'm sorry this is such a noob post but I'm really just starting to wade into this area! Thanks in advance.
