I am putting in 2 subs in my car with a plate so the subs look like the back of the trunk. Problem is that my carpet has quickly deteorated due to my previous box and I want to replace it. I am going to cut out a plywood sheet to fix the bottom of the car then install the carpet on that. The plywood is going to have a hinge to swing it up so I can get to the spare tired + add extra support. I need to do this by saturday before the subs are installed. What thickness plywood should I use (Thinner is better for me and I am going to drill holes in it for weight reduction) and how do I install the auto carpet so it's smooth and looks nice.Thanks!!!
Get a gallon jug of Acetone from Home Depot in the paint department. Pull all the old carpet up, pull up the tarboard sound deadening material, then pour out the Acetone and scrub the floor using steel wool to clean up any glue or tar that might be on the floor. Once you've got the floor pans clean, paint them with flat black paint to protect them from rusting. Finally, you can find replacement carpet at a parts store, just glue it down with contact cement.
Use 3/4 inch partical board not plywood you will have to remove seats and all panels. Watch out for those plastic hook pieces which hold the panels in place in the back
I would use 1/4 pegboard (already has the holes). It is stiffer than plywood. Attach the carpet with contact cement. Good luck.
Trunk carpet and most other carpets are preformed to fit, you can get one from a auto upholstry shop or the dealership, they are held in by push pins to install them, any mods you do to the trunk you have to mod the carpet to compensate, as for the ply wood, you might wanna go with 1/4 inch thick.. not being there it is kind of hard to imagine what your doing, but anytime your modding a trunk, there is alot of problems you can come across.. most modders when doing up a trunk say hell with the carpet and make a custom fiber glass mold (very professional job), so, all in all, write these plans out before you do them and also make some measurements, gotta remember you have only one shot at this so make it a good one.... best of luck to ya.
