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 the amp isn't impressive, have no idea how THX even certified this rubbish.
So here's my dilemma, do I rip the amp off the back plate/heatsink and build my own to fit where the above posted amp sits or do I build a whole new enclosure. Another thing is it even worth messing with the Logitech sub and box? Or do I just build 2 channel amp for my Polks and buy a separate powered Polk 10" sub to run off its own amp? Sell Logitech all together for whatever I can get for it, $80 or so I would imagine, use that to get the Polk sub.
I am curious to rip it apart to see what chip amps they used, I have a feeling they're LM1875s and possibly something stronger for the sub.
Ideas? Suggestions? At this point I need to really think this through and see what's the best possible route.
