i thought about taking out the spare and putting a 15 in there around a coustom box. Then i said, no stupid. By the way right before i got the sol i had a 700 watt max 15 sub and a bandpass box, soon i realized that it wasn't going into the sol because the box took up the whole trunk. does any one want to but it?
Oh and i wouldn't put a custom box behind the seats because i use the storage bins all the time.
