Here is some pics of my center console.

Roger. Will do

Thanks everyone, dual 1 zcon 18's on order. Now it is time for me to work on the box plans.

I have no experience with the Xcon, but I believe you may get better response out of it vs the zcon. Or hell, you could try the Evil, that sounds like it would fit your goal even better!

Sound like a good idea but will be only able to run one (evil)with the price and power handling needed. I want to have clean power going to the subs.

Will I be running a Memphis Mojo 4kw but I still have two Brutus bxi2006 think that the one amp should be plenty.

Looking for low hard bass to balance out.

Well I am look at migrate install into the bed, so I have room in the bed. The amps and the batteries already install in the cab. I am also running In dash epic, Clarion els 740 and mdc360 crossover, she's zxi150.4 for delta lite 10's, autotek sm4-1000 for (4) 6.5, (2) selenium St200 and (6) dome tweeters.

Just low and loud (daily pounder) not really for competition.

Thanks lithium, I know that the 6th order is good only in the range that it's tuned between. The ported box will give me a wider range.

Looking 2 18's zcon or xcon for an Chevy Avalanche. Will be powering by a mojo 4 with upgrade alt, two kinetic 1400 for now. Looking more for sq right now, in at least 13-14 cubes after displacement (slot port). The zcon's do have a lower a qts, xmax, and bl compared to xcon. But spl is slightly higher on the zcon. Later might try an quasi 6th order. Thanks in advance.
