Since I don’t get the noise out of my mind at best, I thought that it might be due to the power stage. I don’t think so, but could that be ? Have a bit of an E-bay bugger and then came across this one.http://cgi.ebay.de/ws/eBayISAPI.dll?… NO I don’t want to buy this But the data is awesome, the part should provide over 1800 watts. The funny, please pay attention to the plugged-in security at the power stage. D But do you think the noise of the Lima and the basic whistle could possibly come from the power amp ? If so, what kind of power amp could you recommend to me ? It should be a 5-channel since I don’t want to have 2 power amps . And should be as cheap as possible . I know that both are more or less resonating , but it shouldn’t be super good , but no scrap . and could you run 2 subs over 1 channel to the emergency ? Then I could save 1 channel and d there the money is spared again. Isn’t the best also clear, but would it be possible ? Are no monster subs or something and I don’t want to have them for the heaviest bang. Are just subs, no destroyers But which companies or models can you suggest, even if your favorites stay away now, because for quality parts I would have no money at the moment. And above all, such a Lima whistle can come at all from the final stage ?
