Alpine Type R 12" Subwoofer Install

[Superpoo]

Hey guys, thought this might be useful if anyone is considering an spacesaving install for a bigger subwoofer. This is an Alpine Type R 12" that I build a custom fibreglass box for. I didn't want to lose too much boot space and was happy to sacrifice some audio performance. Believe me this still goes hard, to be honest I think it sounds tighter than in the larger sealed mdf box I trialed it in.

The install as it stands:

What is hidden by the carpet:

Amps mounted on back of seat:

Nothing special but might give people ideas. I have replaced the front and rear speakers with Type R's also and removed the stock 6x9's. A little bit of sound deadening and the difference from the stock BOSE is remarkable. Hardest part is pulling the 6x9's, half the interior needs to be removed!

I'm guessing but something like 20L? The optimum for the subwoofer (if I am reading it correctly) is 0.78ft3 = 22L, I reckon it is close? With the sub inverted I am using the net internal volume. I have also packed it with the fill stuff.

Are you thinking of setting up a cage to sit around that basket so that nothing pierces the cone?

[Superpoo]

I wasn't. To me it looked OK, the basked protects the cone a fair bit. If I cart anything that could damage it I will need to secure it.

Furry nuts then.
