Adjusting and mounting the system questions

[cloud_171 10+ year member]

Hi, I am brand new to car audio and so far I have been researching on this board. Most of my component choices were based on good deals that I could get:

JL W7 12" in a sealed enclosure built to JL Specs

DLS UR6 (on the way)

Cadence ZRS-10 (150W @ 4ohm, 1500W @ 2ohm, 250w @ 1OHM)

eD nine.2

Pioneer P5900IB (temp)

KnuKonceptz KLM-4 4 gauge amp kit

The box I got was cut a bit too big to secure the sub but I really wanted to hear the sub so I just put it in the box without securing it. So I am at the point of adjusting the gain and I checked the voltage with the volt meter and with the gain maxed out using a 60Hz 0db test tone the voltage is around the 54V which is what I need for 1kw. Does that sound about right? I am too nervous to hook in the sub and max the gain. Also what should I set the phase to? I am probably not going to test it again until my box is fixed.

Another issue I didn't think over is how to connect the nine.2. Could I just run that directly off the battery with along with the ZRS without a distro block? I figure a 4 to 8 gauge distro block would be too small for the ZRS and I really want to avoid getting a 0 gauge ampkit.

Also just as a benchmark when I do have it all hooked up again, this should hit harder than sony xplod in a sealed enclosure? So far it sounds much better than the sony, but I have been too afraid to max out the gain.

Also any ideas on how to secure the sub and amp in a 94 Accord? The only one I can come up with is to put a piece of heavy wood and screw everything town. I have searched and only other installs I have seen are screwing into the back seats but I am not sure how good of an idea that is.

ok, what do you need for rms power? you said 1000. first you need to tell us what load your running the ohms i mean. then i can do the math for you. also sony xplods the red ones at wally world are round 350-375 rms.

also do not max out the gain. your amp is gonna shit out. when you adjusted the gain did you use a 50Hz test tone cd?

"L" brackets from box to car, or before the sub is in place screws with fender washers through the bottom of the box...

oh sorry, 1000W @ 3ohms. I first used a 50Hz tone and with the gain maxed out it did not reach the desired voltage, when the 60Hz tone hit, it was about 54v. I have done the calculations with sqrt(1000*3) ~ 54V and also checked the chart.
