I run Power Acoustik amps right now. I was big into AQ, DD, DC, SD, etc... had to do a REALLY low budget setup this time so I went with a CPT1-5500D, Should get me a solid 2Kw RMS @ 1ohm. not horrible for $200 but the "5500 watt" sticker on it sure annoys me! LOL
Point being, overrated amps are OK to purchase as long as you know what you are getting. If someone bought the CPT1-5500D expecting 3500 rms, well they are stupid but they would also probably be upset. I have seen a few of the "5500's" checked and all were putting pout a clean 2200~ @ 1ohm. so, I spent the $200 knowing I was getting a clean 2Kw, therefore I am happy with it.
