Ok i have an rl-p15 run off a 9.1 at 2ohms. What is the recommended size for a sealed box when giving it 800 watts. I have it in a 2.5 cu.ft right now and i think it could sound a little better. im looking for some more sq b/c it gets really loud and low.

2.1 cu ft net volume (2.31 cu ft internal) is a good size for an SQ-oriented RL-p15 alignment.

Alternately, 3.15 cu ft net volume tuned to 28 Hz is pretty killer too! B)

I dont have much space to work with because my rear speakers hang down alot. It would have to be some kind of sealed wedge design. Im no good with making boxes but if someone could help me with a design I would apreciate it very much.

take the rear speakers out

Thats true I've been meaning to buy some components and a 4 channel soon. Need a better soundstage to keep up with the Rl-p. Was thinking about Alpine type R 6.5 components and and alpine mrp-f240 amp to run them.

X2 on removing the speakers.

You dont need them anyways

if you get the dimensions of maximum space, we could help you on the box design

Ok the space i have would be 17" tall 32"wide 19"deep but the height starts to get smaller as you move further into the trunk hence the need for a wedge design. so the second height would be like 7".
