I bought several Debezt audio amps years ago, they were made in USA, company was in Fort Myers FL. I'm in Clearwater, FL. I bought two DB-U200 amps, rated at 120W/ch 4ohms, 200W/ch 2 ohms, 300W/ch 1 ohm, 720Watts mono 2ohms. The amp is fused at 60amps, requires 8AWG minimum power and ground wire. Built in crossovers, Sub Boost. I bought two of these, used one in my 89 Corvette, driving 2- Peavey Black Widow 15's @ 2ohms, blew out the back window! I still have one new never used, I'm listing it on Craigslist tonight. If I remember, I think I paid about $500.00 each. I'll sell the remaining one for $300.00 I had a Debezt 4 channel driving midbass, mids, tweeters using 3-way passive crossovers. The system was very loud & clear. Sounded like a high end home system!
