That's not a bad idea! My main concern is if the amp I am proposing is going to be enough for the design I have shown.
I also wonder if I couldn't recreat the sunflowers with one size larger drivers......6" woofers and 10" subs....or is that just a little on the silly side. I understand it's a proven design, I'm just trying to make something unique to myself.

Don't know. Paul is easy to talk to so give him a shout on the site or use undefinition1@gmail.com He usually has something new in the works.
BTW, the 8" drivers in his design will rattle the coffee cups three rooms away in my house. Good design can sometimes trump size in speakers.

I've come to realize this the more I research other designs....
While I wait for the 2 week shipment of the first half of my order I will try and teach myself how to use WinISD......could be a lost cause but, it's worth a shot!
When this is all said and done there will be a video of my results. Hopefully I can show what an average person with very little electrical knowledge can achieve with help from around the world

Does anyone have any experience with these?? is it worth it?can i build my own? should I not even bother?

In the meantime I might start on these. This is a very rough draft, It's to get a general idea of the finished product....I'll put full details in the multiway section

Sounds like your having fun and learning about the vast number of choices available. Remember you are on the chip-amp forum and you probably will get better answers on speakers in threads dedicated to that topic or even here:Techtalk Speaker Building, Audio, Video, and Electronics Customer Discussion Forum From Parts-Express.com - Powered by vBulletin
Copper is fantastic for heat dissipation.copper is not that good for dissipation. Aluminum is much better. A proper heatsink done with copper would be heavy and much more expensive.
Only silver is better.
Yes, copper is heavier and more expensive, but in return, it is fantastic. (well worth repeating myself).
The subwoofer being used is a 12" svc 4ohm. 300w rms 600w peak with a FR Res. of 29-150 HZ
I see difficulties with these proposals.So am I wrong for wanting to use another kit bridged for a subwoofer or should I use a different, more powerful chip?
Bridging a pair of amps demands very high current from the amplifiers.
Chipamps in general don't have high current capability.
Bridging chipamps into a 4ohm speaker exacerbates all that is poor in a chipamp.
Expect a BPA300 (3pr of chips) to struggle to power a 4ohm speaker from a 25+25Vac transformer. You may have to consider going to 4pairs or maybe 5pairs of chips for a single channel 4ohm bass speaker.

Thank you for the info. I'll head on over to the subwoofer forum and see if I can find something I like.
Great to see your progress!
I have built the exact same XY kit a few months ago.
I would suggest to replace the 1uF "Wima" input capacitors with 2.2-3.3uF. I was quite unhappy with low end response before the change.
Thanks! I'll try the capacitor swap tonight. I was also unhappy with the low end on the few test runs I have done. I'll run it again when I get the proper transformer in.
Would you happen to have any photos of the completed amp?

Basically, yes.
It would not "put" 200va to one particular amp, it will just "limit" the total current drawn by all amps to 400va.
If it is an AnTek, they claim you can draw more then the stated VA from them. Maybe up to %20?
So your 400VA could actually handle closer to 480VA without issue.
I don't know that you would actually use two separate rectifiers, though you could have separate filter and decoupling units.
