Hello everyone so i finished my stereo install new head unit , speakers & 5 ch Amp . My only issue is the bass . I ordered some small 5 inch subwoofer and i fitted it into the original subwoofer box between the 2 seats . it worked fine but it blew up since they dont have much power. I ordered a 6.5 subwoofer and it barely fits and wont work . The only other option i see is the behind the back seats arm rest is a plastic panel I am thinking to it out and put an 8" sub and boom matt the panel . I dont want a box in the trunk any ideas ?
