Building around 4 type R 12d2's

[Alec Kerchner]

I am planning my system build around 4 Alpine type r 12d2's. This is going in a 93 dodge shadow because i got it for free!

i want this to get low and set some car alarms off. I had 2 12d4s in my audi TT but they ruined the interior in that so i sold them.

So i was wondering what would be a good box size for max spl? Also how low should i tune it? I am adding a second alt and two large agm deep cycle batteries for power. A local shop recommended a Mrx M240 to power it.

Thanks alec

why do you want to set car alarms off?

which type r's? they have 3 different generations.

you'd need like 8 cubes after displacements. kinda hard to fit that in a trunk. you will likely end up having to fire it up, which will make your trunk and rear deck rattle like hell unless you deaden the absolute shit out of everything.
