Best quality grill for my Alpine sub
David M on Aug 28, 2015
My previous SWR-12D2 was punctured and has had inferior bass. I want to protect my investment.
CHRISTOPHER M on Apr 18, 2015
so that i could put other things like bags and stuff in my trunk without having to worry about hurting my sub
Christian S on Jul 19, 2015
The price was the best on Sonic Electronix.

which one of the clear or black brackets for my grill do I install for the SWS-12D4 Alpine subwoofer?
Bryan M on Jul 8, 2015
Best Answer: I assume you are talking about the plastic brackets that hold the grill to your sub. I poked around on the internet a bit and found this: Grille Lock: Type-R (Black): x8 ||| Grille Lock, Type-S (Clear): x8 .

I also read in another review that:
"... Only problem is apline gives plastic spacers. I own the type-S sub. I Snaped the type-s plastic spacer [clear] when fasten the screws. Wanted to get a nice face seal with the speaker, so you can to torque it down. I had to take it apart and used the type-R spacers [black]. Lucky they give you both spacers. The type-R will also work. Only difference the typeR is longer spacers because of more speaker cone movement."

Hope this helps.
