Rear deck port?

[efm80 10+ year member]

has anyone cut a port in their rear deck to increase bass?? I have a 4 door '08 Accord sedan and was thinking of cutting a hole and making a port in my rear deck for my bass to come more into the car. I have heard some people swear by it. does it really work and increase bass alot??? any suggestions or tips about it?? thanks

I've built a box with 4 4" ports coming up through the deck (subs firing foward into the car), it sounds pretty good, better than i thought. nice flat response

this box was tuned to 33hz

this might be the only way i can do my next setup. i dont think i will be able to face both my subs and ports forward with it all sealed off. so i think im going to have to seal my subs off firing into the cabin and my aero ports through my rear deck....

so i would also like to hear the pros and cons of doing this

the box i built like that was for 2 SPL SPLW 15"s (basically P.A. MOFO's) and a SPL 5500D (maybe 2000-2500rms). I was impressed, but with better equipment im sure it would sound real good. but that is just one instance and might not have the same results for everyone.

Yea, if i do what im planning on doing next summer I will have a port in the rear deck firing up...but my subs wont be in the trunk so it isnt the same situation.

I guess what im trying to say is if you have a box in the trunk and this port isnt a part of the box, i wouldnt do it unless youre trying to make a bandpass out of your trunk. But if youre talking about sealing off the opening into the trunk (behind the rear seats) and making that a wall with your subs in it and make a box behind them and the port in the rear window is that boxes port, then yes I would agree with doing that.

Ive done it by taking out the 6x9s and that way it sounds way louder. I didnt see any issues of cancelation. If your backseat does not fold down, i say remove the speakers in the deck if you have them there and try it out. Also, deadening helps bunches.

heres a few pics,

we didnt have a plan really, so we designed as we went to make everything fit.

The ones I've heard sound great, this is a bandpass, here's pics in a '96 Impala SS.
