The speakers are awesome. 100% worth money. But, I just ordered the RP 4500 and to tell you the truth that amp sucks. I have to duo two ohm speakers I have it ran down to two ohm since you can’t run them down to one ohm.I had two crappy planet Audio amps and I was getting way more power out of those amps than I am on this big amp. I went to a car stereo department and they told me that it was probably the amp. That was the worst thing I could’ve heard since I spent all my money on this app. But don’t forget the speakers are extremely worth the money and I’m probably going to buy more.
