Cutting in the rear deck to enhance subwoofer bass

[Jack Yak]

Hi guys,

i have 12" Alpine with P400X1 Mono Block Rockford Fosgate amplifier, the subwoofer in a vented box in the trunk. -Yaris Sedan 07 -

it sounds good and powerful, but as you know that the Yaris trunk's is well sealed !! and this prevent the bass to get into the Cabin !!

so i need to get my bass from inside my trunk to the cabin area, someone told me to cut two holes in the rear deck beside the 6*9 speakers holes, and this will let the bass get into the Cabin !!

he said that it will make a substantial difference !!

would those holes worth it ? anyone done it before ?

any idea about that ? any suggestions ?

It would be better to make the trunk a subwoofer box itself by putting a speaker into the hole to be cut ;)

I wondered the same thing once.. I listened to it with the seats folded down to compare, but I didn't really hear a substantial difference. You could try that and decide whether its worth it to make the holes.

I'm assuming you don't have rear folding seats! right?

Remove 1 or both 6x9 rear speakers and test it!

If you feel more bass comes out through the 6x9 openings then just open up the deck, there is a 2" or 2 1/2" hole right in the middle of the deck, that would be good enough.

Also if you aim your woofer + vent towards the rear of the trunk, the Bass will increase. But you will have to play trail and error here too, and try a few different positions.

And let us know how it goes!

Some thing like this would work but with an Infinite Baffle subwoofer playing in Free air configuration. And his 12" subwoofer wont fit in the rear deck, and probably won't work as IB either.

Also beefing the rear deck to hold small woofers would be a little hard to do, but not impossible, and since he already has this 12" sub in a vented box, I would just test with different options like I wrote above.

I have the same car. Remove 6x9's.

No need to cut holes.

Its not going to sound much louder.

Do you have a type r ? Subwoofer. 600 watts Rms ? Dual 2or4 ohm coils. (Pray they're 4 ohm )

Options :
Bigger box
Bigger amp
2x12's on about 6-800 watts rms is where you'll want to be.
