Here is my story, and it is true.
The first sound system I ever decided to build was for my 1999 Crown Vic P71 (ex cop car). I didn't have alot of money, so I went to Walmart for the audio stuff. Walmart had subs for as little as 20 bucks, or as much as 70 bucks. Brands like VR, Dual, Lightning Audio, Pioneer, Sony, etc.
Well, I really couldn't afford to get the Pioneer stuff, so I went for Lightning Audio, since Rockford bought them out, and they had classic Rockford styling.
I spend 40 bucks a piece on two 12" 750 watt subs. I then spent 90 bucks on the Lighting Audio 750 watt amp. I got some wiring stuff, and finished the purchase with a Pioneer CD player for 120 bucks.
Total spent: $290.00
I went home and had my buddy (who used to build sound systems and compete) build me a custom box. It was actually a real nice box (guy is good). We stuffed it with a moderate amount of synthetic cotton to make it bump harder, and sealed it up.
It sounded awesome. I would blare this thing from sun up to sun down for hours and hours on end. NEVER had a problem.
Over time I always got Walmart stuff, and never had problems.
Well, In May, I decided it was time to put a system in my truck (F250 Extended Cab, lifted 4x4 Diesel). I wanted to do a real good job, so I decided to go to Best Buy for my audio equipment. I bought alot of stuff on sale, so I saved alot of money. But my expenses were as follows.
Kenwood 1200 watt 12" sub- 120 bucks
Bass WorX Ported Box- 100 bucks
Rockford Punch Series P500-2 Amp (500watt)- 350 bucks
Rockford Installation Wiring Kit- 120 bucks
Kenwood CD Player- 120 bucks
Total Spent: $810.00
I feel good about the purchase, I feel it was money well spent. I should really enjoy the superior sound quality since i am used to "Walmart Crap"
I hook it up. Sounds ok, but to be honest, it doesn't sound as good as the walmart stuff. I excuse it that its because I only have one sub and not two like before, even though it is higher quality and 450 more watts.
It beat alright the whole first day, then the second day, the sub blows. It must be a fluke. I go back, get another Kenwood sub, put it in etc. Later that same day, it blows out. I am a little pissed. I go back, this time I get a Kicker Comp. It does good the first day, then the second day it blows. I get another Kicker, and the following day it blows out too.
God Damn....
I get a third Kicker, and before I get to try it out, I sell the truck, but I keep the system. I just put the system in my car last week. Guess what? The sub blows out the next day.
Fvck it...
I go to Walmart, I spend 30 bucks on a Dual 500 watt amp, and guess what? This thing beats WAY louder than the Kenwood or the Kicker, and it has been in my car for a week now, and I have had zero problems.
Moral of the story, just because it is from Walmart, doesn't mean it sucks, and just because it is from Best Buy and cost more, doesn't mean its good.
