Check out what we got in today...1 warhorse and 12 15" l7's. its gona be our show room box or a big truck. havent decided yet.
I've read MakeShift's posts 10 times, while looking at the picture... All I can say is wow, to be able to decypher the amp just from guts and basic specs/info... MakeShift, you understand amp building better than most of us ever will.
I still don't really get it, but here's a dumbed down version, as I understand it. Please correct anything you see wrong, so I can learn things properly.
- The Warhorse works similar to a normal Class D, in that it takes the analog signal (after processing) and changes it into a PWM "digital" signal.
- Instead of switching the power supply-fed high voltage rails (30-150V DC), it switches the 12V low rail, directly. This happens under the 4 Kicker stickers.
- The +-12V PWM signal is run through a transformer that amplifies the +-12V to +- 70V DC(high volt), which emulates a similar analog AC signal.
So this would require high-current/low voltage switching components, since the output is transformed. Not sure if these are more/less expensive, but I imagine they could be more reliable and efficient.
Question: I see a big wire running across the toroids at the bottom. Is the +-12V signal run through the transformer twice, to step up the signal incrementally, or do they just have an odd way of reconnecting with the board?
Haha thats kinda close to what we've come up with so far. Were trying to work with battcap and strap a bunch of battcaps together on top of the supplies. It says it needs 2 200 amp alts and 8 good batteries. We just got it today so everything is still up in the air. but it would be pretty cool to walk into a room and get hit with 12 15's on a warhorse.**** ton of paralleled powersupplys?
Like 8 100 amp ones? lol
