Ok,
I am getting a 2000 or a 2001 Honda Accord within the next week. I would like to put some subwoofers to get some bump in it, but I dont want to tak up the whole trunk while doing it. I'm a golfer, so I want room for my golf clubs in the trunk also. I looked at some Sub Tubes, but I read reviews and people said that they couldn't hear the bass outside the car, and that's not what I'm looking for. I'm looking for something that will bump, but doesnt take up the whole trunk while doing so. Any help is greatly appreciated.

Work the problem backwards instead of conventionally. Put the gold clubs into the trunk and measure to see what space you have left over. This area in lxwxh will determine the cubix feet of enclosure space that you can build a box to. This enclosure will help to determine the number of subs, size of subs and type of sub to match the box best suited to this area, sealed of ported. Do you have a budget for the subs, box and amp?
