[QUOTE="Burkie81, post: 8701278, member: 679309"] So I have an alpine sa60m amplifier new and a new Rockford fosgate p3d412 wired to 2 ohms to match the amplifier both having 600 rms 2 ohms ratings, this said, maybe the sub is just weak, but for 200$ I expected to feel the sub and at best you only hear it and the occasional rattle and then it pops, so I run back to turn down the gain a little and when its " set properly " its non-existent. Extremely irritated. Been following other threads for a week with no positive result. I see videos of the sub review on YouTube and the p3 is shacking the whole car sometimes, but mine is a waste of good materials then. Someone please tell me what your insight might be and one the problem might be. I'm in a 2008 Mazda 3, it's grounded well, powered well, 2 guage wire, the amp never shuts off, the sub just pops and I want to push it way harder but can't. The amp does have a "preamp" set of RCA's, will buying a preamp fix my problem or not ? Anything helps [/QUOTE]
