4 15" sub would be louder than 2 18" sub. I would go for 4 15" :hairtrick:

Hi! Does anyone here ever had underbody lightning kits?? Do you think it look cool to put on at night?? I thinking giving a try on these.

That a very big box. 8 cubic feet after woofer and port displace? I had 2 re SX 15 tune at 37 Hz after woofer and speaker displace in 6. cubic. Burp loud. The re is good for SPL at 35 Hz. Not all sub have to be tune at 40 hz for SPL.

I would make wall of sub if got money, time, and knowlegde. Just do it if you think it right for you. The only problem is that you wouldn't be able to see your rear windows.

You mean you wish you had more money = more power. Need to know what the wall of the sub look alike.

You got a upgrade on your electrical and still got heavy light dimming. You might want to turn the system down because heavy voltage drop can damage the amp. system need more power for sure. Got photo of the sub and wall?

You probably gonna need a external alternator with regulator to adjust the voltage. I wouldn't do this until you fully understand how to do this correct because running a higher voltage can lead to damage fuses and electrical devices in your vechicle. I still reading about this electrical upgrade.

I'm expecting to see that too.

Those are good sub to bump but is it triple stack magnet?
