Am I Hurting My Sub?


Recommended Posts

hi...i have a ported kicker L7 12" in the trunk of my car and at first i faced them towards the front and they hit hard but i wanted louder. I then faced them towards the rear and it sounds alot louder....but it SOUNDS like the sub is actually hitting harder too... Is it hitting the same and just sounding louder or is it bc of the pressure of being sealed in the trunk is it hitting harder?

This happens with MOST trunk cars. Even mine sounds WAYYY louder with the subs facing backwards. Don't worry, you're not hurting your L7. It has something to do with sound reflection off the rear & back into the cabin. I bet it sounds louder outside the car too right?

yea it sounds pretty loud outside the car. I just shot spray foam on the supports of my trunk to stop some of the rattling so well see in a couple of hours how good it works... I'm gonna dynamat it too but the first step is the foam

pretty interesting.....i learned at a very young age that it sounds better most of the time facing towards the trunk unless you got multiple subs...when i was about 17 me and my friend built a huge box had to be about 6 cubes for a jl audio w3 15 and it was on a sony amp i think it only like 300 rms and that shit was bangin...needless to say my whole system was worth more than my car which was a 1979 plymouth :lol:

i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?
