Ask ying before you produce a car! You can steer people in the right direction to car audio? $hit, when you say 300 watts is fine for a 15" L7 you're doing exactly the opposite.
At least you noted the sarcasm. I fail to see where you must pump loads of power to a driver to make it sound good. L7s may need some power but 300w will be decent for the added low end extention that most people want.
director17, stay away from these so called "experts" that do nothing more than confuse the hell out of others to make themselves look good, throwing theories about the flow of electrons in every strand of wire.
Theories? I'm sure that none of what was said in this thread could be produced in real world applications. Switching RCAs or maybe even using a DMM would be too complicated for anyone but an ivy league professor. Conductivity of wire means nothing either; any piece or pieces of wire that you just find lying around the house would work in this application. Don't have wire? Just tape a bunch of spoons together. It's metal, right?
A few years back when I was barely getting into car audio, I had to learn the hard way to ignore these bookworms that think that just because they took an electronics class in college they can impress others and look down on those who haven't.
Oh yes, bookworms who look at the t/s parameters on a driver and know how they influence the sound of the driver. The ones who read all they can to better understand how acoustics work in different environments and varying conditions. Us who actually apply the knowledge we have by testing all the things we learned from reading and studying the subject. Is it all overkill for the normal consumer? Yes, not many people care to understand the BL curve of a subwoofer or how a motor works. Does that mean that you should just go to Best Buy, Circuit City, or some other chain of stores and listen to a salesman who is paid minimum wage and whose primary goal is to move inventory? No, you ask around and read up to the point where you won't get intimidated by some salesman.
The only thing I agree with yingyang on, is that Sony car audio and stuff like jensen is crap. I'd recommend you take a look at the group rec.audio.car, you can get to it from google. There you will find lots of people that have PRACTICAL knowledge about the subject, many of them work as installers and others are folks like you and me that like to do their own installs. Give it some time, one day you will know enough to give practical advice to others.
Ever go to
www.caraudio.com or
www.caraudioforum.com or even
www.termpro.com? You have people there in the industry from companies such as Adire, Resonant Engineering, Elemental Designs, Better Audio, JL, etc. Termpro has world class competitors in Db Drag who regularly exchange ideas and advice.
These are the same people who have worked all their lives in a field which they love and they don't hesitate to inform the novice audio enthusiest who wants more than "go talk to some installers." If you think having MECP certification means jack, it doesn't; every Best Buy installer is required to get certified, not to mention, some of the things in their study guides are completely wrong or misleading.
ying, I'm done with you, so save it for someone who is interested.
Obviously, I am trying to inform the community as a whole and try not to base my knowledge on what a few Best Buy installers have to say.
You want to know where my knowledge comes from?

I don't know everything but I'm not ignorant enough to say that you should just take my word as the end to everything. There is just as much misinformation on the internet as there is of credible information. If what I said is wrong, prove it. I told him how to get the best sound possible with that setup with my first reply; everything else was to augment that reply and maybe help explain some of the common car audio myths that novices propogate. :grinthumb
