Thread: Starting Fiberglass sub box!

So I finally finished up my fiberglass sub box yesterday. Well the fiberglass part was done since 2 days ago but the finishing touches were done today to complete the project. Here are the pics from where I left off last time.

Here is the shell that we left off from last time. I made a mounting ring for the sub and positioned it with dowels and hot glue.



I stretched T-shirt material over the whole thing and secured it to the back with hot glue. This creates the basic shape to complete my sub box.



Next the material is soaked in apoxy so that it hardens in to a surface that I can lay down fiberglass onto.



This picture shows the front after 2 layers of fiberflass. You can still see the blue material through the glass.



This picture is after about layer 6 where you cant see the blue much any more and it was becoming the right thickness.



After I let it set for 2 hours I cut all the excess off the sides and cut the hole out in the middle and also a hole in the back for the wires to come into.



I picked up some gray and black carpeting to finish up the box. The carpeting went on easy with some 3M spray glue.



Here is the sub in its placeall finished and blended into the car. THe sub is blurry in the picture because it was on at the time. Some foam tape helped to seal the sub to the box to prevent leaks.



This is a completed shot of my trunk just how I had planned it to look before starting this project. Also note the black material on the trunk lid covering the shiny silver sound deadening material. The sub sounds great and hits harder than it did before. I may have to turn down the power to it to prevent over driving it as it moves up to 4 inches in and out when all the way up.

So what do you guys think of my first sub box? It took a few days but now the sub has really settled in and it is using the whole trunk to reverberate the sound and is much punchier and louder than the old bandpass box!

lol It was my first time working with fiberglass. It's not that hard. I just read a lot about it before I started and asked a lot of questions here. I'm sure you can do it!

Yeah it cost about 150$ total for everything. inc the resperator tape rubber gloves etc etc. I could have used wood at some points but decided to go with all fiberglass.
