How many Alpine Type R 12" subs in a hatchback?

Question

I want to get subs for my 2008 VW GTi, and was wondering if one sub would be enough, considering it's a hatchback. I'm looking for pounding bass but nothing to make anyone in the car go deaf.

Answer 1

"I'm looking for pounding bass" then you will need one h**l of a 12, and it needs to be able to handle at least 400watts RMS

when it comes to bass there are a few important factors like

the box being used should be ported for more bass and the RMS (continuous) wattage is important but bass is also determined by cone area (the subs surface area) and one 12 cant more as much air as two 12s

so even if you had one 12 getting 400watts RMS someone with two 12s getting 300watts RMS total will be louder

Answer 2

Then one 12" sub will be plenty.  h**l, one 10" sub would give you enough bass to make your head hurt.

Answer 3

i have 2 12" subs in my car and its in the trunk of the sedan. anyone sitting in the back seat is basically bouncing out of their seat so 1 12" should easily do it.
