8 12"s in a trunk?

[86yota 10+ year member]

Well I am considering adding 4 more CVR 12"s and another Massive p1500.1 amp to my Merc. Unfortunally, I will have to switch to a sealed enclosure instead of ported. Will I still be noticeably louder with double the cone area and power with a sealed box? I dont want to run a wall, but I can get about 10 cubes out of my trunk before sub displacement. Still not enough for them sealed im sure, but its all I got. What would you guys suggest? This setup, or 4 CVX 12s in a proper ported box on 3000 RMS? Gonna be running 1 extra Batt for now, but I know it wont be enough. You guys decide for me! I want to be breakin a 140+ in the trunk.

I would do no more than 4 12's ported.

I know those cars have big trunks, but 8 12's shoe-horned into there will not be good.

why not go 6 12 Cvrs ported.....

but if not go CVXs

Why would 8 12s not be good? just not enough space?

if you want to break 140's in a trunk, then get a new install... if you cant break 140 with 4 12"s then going to 8 12"s probably isnt going to help you do it...

i was doing 135 on the Tl with a single 15" in the trunk of a taurus running off of about 800 watts, for what its worth. i dont see any reason why 4 12"s couldnt do 140's in a trunk.

that, and because more is not always better.

4 CVX's Ported

I personally see the 8 CVR's turning into one hell of a headache.

Id like the 4 cvx 12s with 3000watts....that should be able to break 140 in almost any box haha....good luck man

If you can't break a 140 with even 2 12's then something isn't right.

I have no sound deadning, and only 1500 RMS right now. No extra batts or anything else, probally low voltage.

Sounds like you already know your system's weak points... why are you looking to upgrade cone area instead? You are trying to get fancy with 8 12's when you dont have the fundamentals done yet.
