[QUOTE="hispls, post: 8267911, member: 614752"] There's more to that story than the difference between 80W and 150W, because it's not just the meter, it's the actual perceived difference in loudness of 3dB which isn't much. If you have a 0-35 head unit it's about 2 clicks of the volume knob. I asked about a meter because if you ever looked at a meter while listening and actually turn things up or down 3dB you would realize it's not very dramatic. Noticeable, but not dramatic. Furthermore when you're pushing the drivers to their upmost limit you're getting into distortion and compression from the speakers so it's likely you'd have actually less difference real world. With just a DMM you can try it for yourself with your amp. Put it up to a high listening volume, test voltage on a test tone and back down your volume until you're at HALF POWER. Now you know how many clicks of your volume knob 3dB is (or halving the power). Now put in a music track and compare playing music at one level on the dial vs. the other. It won't be very much on your volume dial and you'll see what I mean. Now assuming you told OP to get into a 125 per channel Zapco, Zed, Audison, or other high quality, regulated power supply amp, I'd think the difference would be more noticeable, but not so much just jumping up a size of the same Chinese mid-fi brand..... and likely still won't be the silver bullet to fix what his problem is (which is lack of a subwoofer, lack of proper set up of his processor, possible poor locations of the components, and even some other random install error). In short, after a point, throwing more power at things becomes very low return on investment. [/QUOTE]
