[QUOTE="hispls, post: 8755332, member: 614752"] China will build basically what you tell them to build. Companies like Kicker have been building their amps in China for 20 years or so and they're known to be rock solid. Kicker is, however, doing R&D in house with real engineers, paying their sweatshops enough to maintain a high level of build quality, and has implemented some form of QC or oversight to maintain high standards on what comes off the line there. IF you call up the sweatshop and ask them to build an amp that makes 3000W with FOB price of 150$ they're going to cut whatever corners they can to get you something that resembles what you ordered at the price you negotiated. The issue here is twofold, first the consumer doesn't want another 1000$ 3K amp, they want a 300$ 3K amp, and second it very probably is more profitable to sell 300$ 3K amps every couple few years and eat 10% or so in warranty claims than to sell a 1000W amp every 10 years with a 1% rate of failure. I could be way off and certainly there's more factors, but this explanation seems most probable, and I'm very confident rates of failure on every piece of electronics being sold by established companies are very well known. 1/2 ohm load on a full bridge amp is absolutely torturous on semiconductors though (how many 1/4 ohm rated half bridge amps can you name?) and there is really absolutely no benefit with this style design. Personally I'd like to see more companies following the lead of Brazil making 2 ohm versions, but again, I think a lot of this is just providing the market with what they think they want. [/QUOTE]
