Entertainment systems / Audio?

You need a dvd receiver
I pick pioneer or alpine.
4- 6x9" speakers. They sale enclosures that you can hang. I'd pick "3 ways pioneers that have the most "rms watts" ratings, about 65 watts rms.
2- 5-1/4" focal components for the front.
I'd get a 10" woofer, "focal"
Then buy a 5 channel amp from either JL audio or kicker.

The most expensive the wiring you can afford the better quality you will have.

You're looking at about $2k of kick-#### sound system.

 

I find that most speaker setups are fine, it's just the bass that lacks. I was thinking of just buying a standalone sub, like 200-400w. If you ran RCAs from the head unit to the sub would you still get audio from the trucks speakers?

Another thing i was considering was just getting a really good 2.1 setup and running it off the inverter, since I only listen to music with my iPod Shuffle plugged into the head unit anyway,.

 

500W in my 2000 cubic foot living room when I was playing Independence Day shook the ceiling enough that my upstairs neighbor thought a plane had crashed at the nearby Air Force base.

12,000W is enough bass to power a concert venue. Ever notice that bass is louder outside a car than it is inside the car? Bass waves needs room to develop, which is why you need insane amounts of power in a car. You would need less power for the same SPL in a tractor cab.

 

For me, I could care less about it being loud and more about it being clean. Sure there's a comparison between volume and distortion...I understand all that. I just like my lows "Low" my mids "Mid" and highs "Hi"

Doesn't need to be a super hi end deck, but one with a decent interface and MP3 connect ability along with the needed RCA input output.

As for speakers, separates in the form of tweeters and a mid range, connected to a decent amp and a crossover for adjustability.

Currently looking at purchasing a Focal setup. 2 woofers, 2 mid range, 2 tweeter component setup and the crossover, Focal 6 ch amp and a Pioneer dash unit with an Axxess steering wheel interface.

 

Our trucks are not designed for any definition of sounds In cab.
We don't pull trailers with mercedez'
You need good power; why? To go deaf? No.
Because your radio plays its best sound at mid high volume, not up to the max. So when your playing your high power high wattage stereo and you raise the volume halfway, you'll get the best definition of sound. Now every radio/stereo/headunit/receiver is different.
A 200-500 watt amp can power enough bass, yes. While heating up your cab and sucking the juice from your batteries like your engine sucking diesel going up on magic mountain Heavy.
A bigger amplifier (specially a class D) will work with less effort, give cleaner, better tunes and work cooler.
You get what you pay for, whether it's a plane or just a car stereo.

 

Comparing a home systems power to car audio is silly.

You would need far more power and subwoofers to create the same SPL in a semi-truck vs a car due to pressuring the volume of air. On top of that, the sleeper would flex quite a bit and the cabs are far from from air tight. If it was all about wavelength you wouldn't see external reinforcement and inch thick screwed in windshields.

This is the the Grandma of SPL's Bronco RIP!
Old school IASCA judge and MECP installer here. I've judged Finals winning cars and helped with design of one as well, back in the day.

OP, the reason there isn't a manufacturer doing this is it is a very broad market with a lot of variables. When you couple that with low pay, fear of loss, theft, etc it minimizes your customer base. Your target audience should be o/o and l/p drivers. They are the ones with money. Good luck.
