Great to keep your subs safe and not let them bounce around your trunk



Holds sub in place

Crutchfield Customer Review (What's this?)

Used these brackets to hold a Sound Ordinance B-8P powered sub. Mounted in the corners of the box. Holds them in place well. Yeah, I could have gone with hardware store L brackets but wanted an clean looking installation. The black color and rounded edges gives me that look.

Pros: Holds sub securely.

Cons: None

Not needed

Crutchfield Customer Review (What's this?)

Found out I didn't need these brackets since my sub box does not move in tight trunk space. I am sure they will do fine if you don't plan on ever moving your sub box out of the way.

Pros: good quality brackets

Cons: make sure that you really need this before buying

125B70KIT speaker box brackets

Crutchfield Customer Review (What's this?)

It looks like Crutchfield is using a different supplier for these box brackets, because I
also got the ones with two holes on each "L" bracket, instead of the four holes like in the
picture. Anyway, they do the job they were intended to do, which is to hold down securely
your subwoofer or full-range speaker box inside your vehicle. You can always drill the
extra holes in the brackets, if you need extra hold-down power, but it's not necessary.

Crutchfield Customer Review (What's this?)

They do what they were made for... to hold your box in place so it doesn't kill you when you get into an accident. But the ones I got only had two holes for each L bracket, not four like in the picture... But the box still seems stable and not shifting around the back.



It Does The Job

Crutchfield Customer Review (What's this?)

Buying a new sub and box? Make sure you secure them to the vehicle or that box will move around, destroying everything in your trunk including the box! Plus, it thieves actually make it in your vehicle, they will have a harder time removing that box!

You may find something similar at a hardware store that you can make (and maybe cheaper), but it's so convenient to add this to your Crutchfield order.
