    93 chevy silverado small SQ build

    Ok, so im about to tackle my truck design. I currentyl will be running two RE audio pro sr subs. 10" My box is going to be like a box under each side and fire the subs towards each other and place the amp in the middle. plexi on the front to see the subs. I figure if i angle the subs towards the front a tad bit I should get a real good sound from them. Im still unsure on porting the boxes or to keep it sealed. Sealed has always sounded great to me, but ill get a louder sound from ported. Either way it will be a unique build for sure. The rear florr hump is going to be removed becuase the truck has a body lift and nothing is under there to even hit. Itll make my box building easier. Ill get pictures once i get started on it. Still thinking ill have to do a seat raise of about 2 inches.

    Re: 93 chevy silverado small SQ build

    So changing ideas, going to throw both subs over on the passenger side under the seat firing forward. running the port toward the driver side, and doing the amp rack under the seat behind the driver. Using winsd with my subs, my port should be tuned around 28-29hz to have a nice flat response line. Port should measure out to be 3" by 12" according to there program. Im just waiting on a router to start so i can get some nice circles. Box is going to be roughly 1.9cft before any speakers or ports, so i figured it all up for a 1.8 cft box. Hopefully it gives me the pucnh i need.

    I would put the subs on drivers side port passenger side. 8f you have any port noise putting it opposite side of you will help and you want hear the plastic vibrating from the air coming out of the port and hitting the truck panels

    Re: 93 chevy silverado small SQ build

    i thought about that, but most of the sound is going to come from the port, so i would believe it would be louder that way for the driver. ive noticed with a plain ported box thrown on the back seat, its loudest to my ears on the passenger side with port and sub facing forward. so in theory it would be the same under the seat. the box will be either side universal, ao i can always throw it under either side.

    If you port to the side rear corner the box will load off the rear door and amplify the subs out put kinda like subs facing the rear of a trunk car

    I dont have a 3rd door. I thought about that as well. I can move the port around since my terminal ring is 3in, and so is my port. so ill have it positioned on each side and swap around till i find my sound.

    That can work you need to have at least 2.5cubes of air space though of the box will be real peaky. Unless you are using dayton ho

    2.5?!? The subs recommend .65 compact or 1.0 optimum. 2.5 seems real large

    No, the .65 to 1.0 is for ported. Sealed is .3 to .5 I believe I'm going to get around 2-2.1 Cft before subs and port. So I think I'll be happy. I'm not going for spl level.

    Re: 93 chevy silverado small SQ build

    I'm taking all advice. I just wish I knew whether to stay around recommended or go a bit bigger. I tried winisd with 2.5 Cft and it showed a higher peak at my port hz but wasn't as flat of response. I'm not sure. I've always built an ran sealed boxes.

    I can put money the if you build it bigger and keep tuning low it will sound better.

    Winisd is for houses not cars. Good for finding out port legths but not for modeling subs in a car

    Re: 93 chevy silverado small SQ build

    Ok, well I have it tuned to 28-29 hz. I believe I can get right at 2.8'cft feet in the Area Im building by measuring it. But it's a big box. Here's another question. Is a bigger box going to give the sub more power handling? Or smaller box? The subs are rated to 320rms but I want to be able to safely run them at 400-420 each.
