I don't really chime in about car audio, I have been around it for years, and have mostly read bits and pieces about the industry to keep up to date.
Plus I used to work at Circuit City(Yup, remember them?), talked to reps, and got to read some of the industry only magazines and lit.
Car Audio is one of those industries, where they really stick it to the customer, whom they assume don't know any better.
Believe it or not, one of the TOP items at CC, where they made the most money(basically mark-ed up) was CABLES. I got everything at cost. At the time I purchased a 3' long Monster Cable my cost $8, customer price $90.
Got a replacement LCD screen for my Sony laptop, and its made by LG.
The thing with car audio is look at the price tag then take more then 3/4 of the price, and you got around what it costs. As for cables its the biggest scam. Do you really think(unless you are some type of audio savant) that you can tell the difference between a $20 cable and a $400?
esp. in a car with all the other ambient noises.. I'm betting on no.
My point is this, everyone has their own opinion on whats good and whats not. Someone might have told you that brand X sucks, so you think "He knows what he's talking about." Then you have it in your mind that Brand X sucks, nut what you don't know is that Brand X, and Brand Y, are both made in the same factory, with same materials(design of product is of course different story.)
My $4000 Samsung LCD is built in the same plant Sony's are.
Like our Impala's, they are just Caprices really(don't flame you know its true.)
Why did I even write all this? Dunno
At the end of the day, its your money, car, and ears.
