Hey i've got 2 12" Kicker S12L7's and a amp that runs it's rms power. Right now i've got a sealed box and it knocks like crazy inside the cabin but when you open up the trunk it sounds like shit. Would this problem be solved if i got a vented box?

 

Does it sound bad from inside the cabin with the trunk open, or when you're standing next to the open trunk? How does it sound bad?

 

it sounds alright in the cabin when the trunk is open, it sounds horrible when ur standing right by the trunk when the trunk is open. It sounds bad because it doesnt give you the low bass that you want. That BOOOOOOOOM sound lol. Instead it sounds like a speaker kinda.

 

I'm not sure what to say--for me, I'm most concerned about getting the subwoofer to blend correctly with the rest of the system (from inside the car). If it sounds good from the driver's seat, I'm not sure I'd do anything to it. They say sealed boxes are generally better for sound quality, but ported boxes produce more sound with the same amount of power.

 

do you listen to the system inside or outside of the car? if it sounds good inside, should it matter what it sounds like outside?

 

IS the xover in LP or Low Pass? It sounds like it's full range or high pass on the amp...

 

it does matter what it sounds like outside cuz me n my friends like to chill n listen to it in a parking lot sometimes if we've got nothin better to do.

 

You guys need a hobby. Maybe volunteering? I recommend Habitat for Humanity - they can use some strapping young men to help out.

This reminds me of the guys years back who wanted their bass to "carry" outside the car. Turned out some of them were dealers wanting the ice-cream-truck effect.

The woofer sounds like a speaker - that's what it does. It is designed to compress the air inside your car. Compressing the atmospherre of an entire planet - that's a different task...

 

no he's right - i have them in a sealed box as well and when u open the trunk it sounds horrible - very distorted i am working on a vented box as we speak

 

and yes it does matter b/c i don't want to be rolling around with it sounding like $hit

 

Ah... so it's about how you look to other people?

 

wow this is retarded last time i checked this was an audio forum

 

This thread is funny.




I was thinking the same thing elduderino was with the amp settings.

Check all the settings on the amp to see if it's set to that of a full range speaker box and not a sub. Low Pass is the answer my friend.

 

i'm getting myself a vented box

 

We all want good sound, and good sound is often a difficult thing to describe with written words.

I have a fairly balanced system, and the bass is much different inside the car as opposed to outside with the trunk open. Before you rush off and build a new box, I'd experiment with different levels on the sub when standing outside; having all the doors open, etc. I'm having a hard time believing that ported vs. sealed is going to make it sound tremendously different when standing next to the sub but far away from the mains.

 

Everyone chill.. Different strokes for different folks..

 

Remember, there's a reason foghorns use low frequencies--they carry better through the air over distance. To make your system sound good at a distance would likely require you to increase the mids/treble by opening the doors/windows or changing the eq or gains.
