I am going to be designing a custom box and have many ideas but am wondering what is the best for good SPL and some nice boomy bass. Do you think its best to have them shooting right at trunk, how would it sound pointed straight down mounted on the trunk deck? I plan on either going with 2 10'' Image Dynamics DVC's for the small enclosure space or the ADS DVC's.

Also want to run the whole system off one 6 channel amp. I got separates in the front. Wut 6 channel amps you guys like? Anyone you think is good and semi-affordable?

Also since the subs are 4 ohm DVC I could drop load to 2 ohm and run it mono on 5 channel amp?

Thanks for imput.

For what you're looking for, DEFINITELY aim them towards the back.

you mean like at the back part of license plate when trunk closed?

for a few reasons...

1. the rear deck is made of very thin, flimsy sheetmetal and is not rigid enough to support the vibration of the subs.

2. you'd have to buy specific subs designed for free air applications... and to tell you the truth, it's difficult to get them to sound good.

3. Whenever you use subs in a free-air setup and not built inside a box, you introduce the potential to hear the air escaping out of the voice coil through the hole in the center of the magnet. Depending on the specifics of your application... this could possibly become an annoying sound and detract from your music listening.


My suggestion... one or two subs in a sealed enclosure yields the best all around sound quality and still a decent amount of spl.

with a baffle board. Yes, aiming the subs towards the rear of the car does yield boomy bass, but at the same time, you are wasting a lot of potential energy. This is great in hatchbacks, but not in trunks. Think about it, bass is nothing more than moving air. If you want to hear and feel the bass, you have to allow air movement. What happens if I throw you into the trink and slam the lid? You kick and beat the hell out of it trying to escape. Subs' output is the same way. Close them in a space and their output is exerted on their surroundings. Rattling trunks, plates, bumpers etc is all wasted acoustic energy. Facing them forward and isolating their output to only moving forward into the passenger area will allow for the most efficient design in your situation.

But they are in a box which is also extended to the floor, I don't think he was talking about free-air speakers

I'm not going to use free-air,I'm building enclosure.

Do you have the subs pointed down or up through the rear deck?

Yes, the back.
