subwoofer in a 355 gts

I have seen some pics of subs in a GTB and spiders. I have a JL 8w7, zr components, and 5 channel amp I pulled out of my last car. The w7 requires quite some airspac. The only place I can think of to get it is between the seats a la the hi fi sub in the 360. However thats where the roof goes. I really don't want to put it under the bonnet. Can anyone else give any insight? I need almost 1 cu ft of space.

Also can a speaker with 2.65 in mounting depth fit in the doors? I believe factory speakers about 2.15 inches.

 

Under the bonnet is very audible.......... here is mine.....

Really? Even with the cappy and hyperflows? I swear I can't hear anything but the orchestra coming from behind unless I drive under 3500 rpm.

 

Thats pretty cool. Does it put any stress on the bonnet lid? Any vibrations or anything like that.

 

Yeah you can hear it fine most of the time.............after 5k RPM all bets are off.... !!!

No stress..........but when I do use it...... it is never very loud...

 

No--They will not fit. I had to put a spacer in between the door and speaker to get mine to fit in there. Just installed JL Audio Components in the car today with a Alpine head unit...

 

How much room is there between the mounting surface and the door panel when it goes back on? (ie how big of a spacer is allowed?) My car is in the shop right now so info like this isn't readily available to me.

 

Who needs a subwoofer in a F355 ? Just add a tubi and you're done

j/k I think you can only place it behind the seats or in the front. Or buy a soft top targa roof (aftermarket) and leave the hard top targa roof at home. It's much much smaller than the hard top.

 

Consider ditching the 8W7 for a 8W0 (if you can find one) or possibly two Focal 5" woofers (I forget the model number). I have done the Focals in the passenger footwell in a small (if I remember correctly a 0.45ft^3 box, ported). You will only loose maybe 3" off passenger foot space and the car will look 100% stock. Sounds AMAZING too.

Where are you located ? -- I can help you to locate a qualified shop in the area if need be.

I used a 1/4" spacer and it is VERY close...almost touching--Actually when the woofer hits hard --it touches a tad...
