A friend of mine is give me his old system . A head unit amp and 2 10in Speakers. But i have no idea where to put the Speaker im willin to put only one i Want some room in the trunk and my Tool kit. Is there a way to put it under or behind the seat or in the rear tray?

 

There are several people who have put a sub in the passanger footwell at the front (see link below). This appears to be a very popular spot. Under the seat does not have enough room. If you have your softtop, that area also will not work well. Some other very creative people have installed them into the secret compartment. This can be very difficult.
