ok guys, its time for me to re do my sub box for the new truck. my question is how can i save weight? the previous box that i had was 3/4 mdf. it housed 2 W3v3 subs and a 500/1 amp. my thoughts were to make the trim pieces on the floor and the rear wall of the box out of fiberglass. but im not sure if the rear wall of the box will be strong enough.

my second thought was to maybe make the box out of a thinner MDF and reinforce the interior of the box with fiberglass.

what are your guys thoughts?

i want to save weight to keep performance but don't want to sacrifice sound quality of the subs.

 

its a truck. not a porsche

 

the amount of weight your wanting to save wont do much for performance...just stick with what you have rather then compromising sound quality

 

yeah its a truck and not a porsche. but when looking at performance in the eyes of 1/4 mile times every 100 pounds lost is about a 1/10. and in the eyes of gas mileage, well , gas isnt getting cheaper exactly. i was just wondering if there are ways to do it without sacrificing sound quality. if there isnt then i wont do it.

styx, i know you didnt mean any harm by it. but if you dont have any advice then dont post. i didnt ask for a comment like that. im perfectly able to make a decision based on what is possible and what isnt. and whats to say that i dont have plans in the future to develop light weight carbo panels to replace the sheet metal? it may not be a porsche but i can damn sure make it one hell of a performance truck. have a good one. by the way the truck looks good and the system design looks good as well.

 

cool....what all you got done performance wize midnight? what kind of truck ( year, motor, etc) you kno...sounds interesting

 

its a truck, not a dragster

 

ok well apparently you have something else going for you. but thats cool to each their own.

marc, nothing is done to it yet. i took delivery of it 2 days ago. but right now i have a 2.5/4 drop and 22's sitting in the apartment waiting to go on it. then i have to put my system back into it and then i have plans for a whipple.

 

so wait..... your worried about performance/weight reduction yet your not worried about the added unsprung weight running 22's?

 

@ styx.

Just a thought, but if you are talking about taking it to the track, why would you race with subs in at all? That's like racing with an extra passenger -- pointless and just extra weight. Anyway, to "answer" your question, I don't know much about fiberglass, but I would think that mixing materials would just be silly. If you are capable of making one wall of fiberglass, why not make the entire box of fiberglass? Fiberglass is fine for SQ, assuming there aren't any leaks and whatnot...

 

when i go to the track i will remove the box and put on different rims. the main factor of looking to do some weight reduction on the box was for daily driving. but if its not worth it then i wont do it. i was just looking for some feedback on if it was worth it or not.

 

Unless you are going to make the whole box fiberglass, I don't think it would be worth the trouble. The weight reduction would be so minimal that I doubt you would see hardly any change at all. You just gotta remember that the Speakers are a large portion of your weight, not so much the box (though, yes, I realize the box isn't exactly feather-light). So... in MYYYY opinion, it's not worth the hassle to whip out any fiberglass unless you are going to go all the way and fiberglass the whole thing.

 

thanks grif. thats what i was looking for.

 

not worth it if your gonna run 22's daily

 

thanks styx. thats the answer i was looking for.
