Hey,i got a boston SPG555 Subwoofer with box up for grabs,price is $350
Paid $500 for it and used for about just a few month's.
this woofer sounds awesome,long distance traveling deep bass.
Basicly this is the sub made by boston along with box to compete with the JL Audio w7. The box is ported off the Boston acoustics factory
IM me of send me an email im in the tri state area

here's a pic of what this set up looks like

 

does it fit in the trunk/?? i might get that to replace my alpine ...

 

it should, e60 has good size trunk space. also just for reference here's a pic of this sub outside the box
just to show why boston gave it this size box off the factory

 

well.. most box did not fit in the trunk.. can you give me dimension of the box size please...

thanks
