Hello, I have a RIESEN problem here. I recently installed a new front system (Mac Iron 2.16 in the Golf 3) and it hangs on my 4 channel power amplifier (Pyle QA 4400 III, 70W RMS) O.k. it’s just beginner compo. and without insulation of the doors it will never sound perfect. So much is clear. But what doesn’t make sense to me at all is the benefit. Honestly, the maximum level of the system at the power amplifier is ridiculous, comparable to my 6*9 coax on the radio. NO WITZ! With minimal higher volume they already sound overdrived. Further a brittle sub hangs on the 4 channel, which runs (for my conditions) with good pressure. I know that the Mac Iron 2.16 can’t get quite at Cantons or so, but nevertheless I can expect good sound or level, right? According to the test these are “very good”. A few data – power power amplifier on channel at 4 Ohm: 70W RMS – front system: 90W Nominal, 150 Maximum, 91db My question: Where could the problem lie? I mean 70W R MS would have to be enough to assign the system if even the sub is well supplied (by the way also Mac Audio 🙂 Bass Reflex box) And please NO suggestions about other boxes, amplifiers and so on I BET for this there can be reasons, PLEASE give me some! So, who made the trouble to read this, THANKS!!!!!
