Keep in mind that the recommended enclosure assumes you will be using recommended power. You amp is nowhere near that.

it is going to a a new box. The amp is currently in 2 ch mode. I cranked the system yesterday to my "Ear defining" levels inside the car and then opened the trunk to see what the movement of the sub, its barely moving by my standards.

Not enough power.

Not enough power.

I was not asking the sub to do more, I do not require a lot of SPL....... for now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

wait till you see how drastic the output drop is. A 12 is roughly equal to 2 8s and a bit more in terms of cone area. the E8 is not beefier by any means and the power fed is the same. You can expect a huge drop in output.

Expected that I will loose output at MAX levels, but I don't think I would be using near its max output nor would I want to be inside the car when that happens //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Understood that I would need to turn up the gain and use more power from the amp. Will find out later how this goes

i checked the specs for the e8, it says 0.5 to 0.75 for a ported box. how come i see e8 on larger boxes on Youtube ?

its probably within specs, The box looks big due to a good amount of port area most likely. Drives the gross cubic feet up high but the net cubic feet is the same.

Also if they underpower the sub or if they want deeper bass, they'll probably put it in a bigger box tuned lower.

How big a box can I go with the e8 ? How about the port (slot) area ?

So I'm confused as hell. I thought you wanted as small as possible. Now you want as big as possible. If that's the case then keep the JBL and get a decent amp.

I want to maximize a certain space in my trunk. roughly 32 long x 6-8 inch depth x 15 inch high. It might be slanted at the back. but i want it as thin as possible...

my apologies for the confusion...

Dont listen to slow ride. Hes clueless.. The e8 will take 600 all day..

I got the e8 !!!

we had to increase the gain, but it was doable. The box we used is about 2.5 cubic feet, sealed, not ideal, but it did good bass, so a proper box will only make things better //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
