i had put one ten inch L7 and didnt know if i was gonna add another or not so this is how it looked right after install . decided to stay with one ten and have since mounted the amp on back of the box and shoved it into the corner . It knocks hard for one ten . 2 would be just right to even it out . Its not a sound quality sub IMO but more of a low boom boom hitting sound but thats what i wanted just a little more bass . At first it sounded ok then ripped out the foam or whatever that was in the holes next to the rear deck subs and made it sound alot better . only drawback is somtimes when knock the shyt out the system the smell of amp kind of lingers into cabin .
mounted the bass boost **** where the ashtray used to be , they wanted to mount it right by my knee under the dash but i said nah put it somwhere where it doesnt stick out
