[QUOTE="hispls, post: 8781355, member: 614752"] 4x100 +500 definitely won't get you anywhere near a proper rock concert, but should be plenty loud enough that you'll want to turn it down to have a conversation and what you described in your OP is certainly at the point where you will begin to get very diminishing returns from adding more power without figuring out places to put more speakers/cone area. That's roughly what I have in my pickup and in my Corolla and it's decent for normal folks. Getting loud bass in a car is super easy compared to in a big stadium or concert venue so really a good ported 15" woofer on 500W can get you around the feeling of a concert on the low end, but consider the mids and highs at a concert are being played through huge stacks of large diameter full range drivers and horns. I have seen many people (typically Brazilians) loading their doors with PA midranges and horns and mostly they sound like absolute ****. Some sound OK standing 20 feet away, but mostly it's just not practical to get that into a car without really getting creative and being good with planning and EQ/crossover settings. The point being 140dB at 50hz in a car is do-able, 140dB at 300hz or 1000hz will be extremely difficult in a vehicle (though easy to do with PA stacks at a concert). Yes power is super cheap now, even made in USA stuff (when adjusted for inflation) is cheap compared to the buck a watt we paid back in the late 80s early 90s, head unit technology and digital sound processing has also gotten really good and really cheap, and speakers have evolved largely to be grossly inefficient, but to handle the loads of cheap power everyone has these days. Not saying the modern speakers are bad, there's some fine offerings and even some middle of the road priced stuff can sound fantastic, but they're not efficient like we used to get. [/QUOTE]
