Some people will develop their own car subwoofer enclosure out of wood since it is mosting likely to be much cheaper for them normally. There are troubles with this that people could face though. Timber is fine for some people but other individuals need to have the ones that are constructed of fibreglass.
When somebody has a smaller sized vehicle, they are typically trying to find extra room all the moment. This can be a trouble if they need to have a big box sitting in their trunk or rear. Fibreglass is mosting likely to permit them to have even more area and permit them to tuck their subwoofer in where they desire it as opposed to where it will fit.
