I've always had hatchbacks, and have enjoyed the sonic benifits of them greatly. I'm just about to do an install in my first vehicle with a trunk, and I'm curious how bad the SPL losses will be trying to get through 5" of seat foam. I'll be running 300rms to a 10" Comp VR, will I even see 120db with this?

can you pull your rear seats down to expose the trunk? if not, then your up poop creek without a paddle. you'll still get a lot of bass, you just won't get the spl.
i hooked up a box in my GF cavy (w/trunk, no access to cabin), and it's tuned low enough so that the bass still comes thgough the trunk and into the car, so that you can feel it and hear the pounding, but on a meter it doesn't displace as much air = less SPL.

 

At least you don't have a metal wall like I do

 

Take out the rear speakers, that will be a few dB gain since your seats don't fold down.

Not really much else to tell ya, other than test all different box positions to see what works the best.

I was thinking the same thing with threee 12s in the trunk.. [img]graemlins/cry.gif[/img]

 

What kind of car is it??

When I had my Sunbird with a solid back seat,I went to the junkyard and grabbed a 60/40 split seat back and put it in place,ripped out all the sound deadening and voila!

Just my own experience...don't know if it will help...

You could also run a bandpass box and have it ported up through the rear deck...

Somethings to think about!

 

ask one of the mods, they are Gods at this SPL thing
