DIY boombox design

[gonzada]

Hello guys, i decided to build a boombox using:
2x skytec 6'5 PP 200w, 100w rms
2xhifi tweeters 140w, 40w peak
Both are 8ohm
So i got to a point where i cant find a suitable amp to run theese, i calculated that this setup would require 48v to run.
What amp would you guys use?
What else would you recommend using with this setup?

Consider bi-amping your speaker system. Split the sound spectrum with a crossover, then amplify. You need twice as many amplifiers, but each uses less power. Your total power usage is lower.

I looked for a Skytec Speaker Manufacturer but instead of finding one I found millions of ebay ads selling cheap Chinese junk with the name Skytec on them.
I found a datasheet for a 6.5" Skytec woofer rated at 125W RMS but it had no details.

An amplifier with a 48V power supply probably has an output of 45V peak-to-peak which is 15.9V RMS which produces 31.6W into 8 ohms.
