Streetwires CBR44A Combo Fused Distribution Block is an ideal power distribution solution for anyone who needs efficient, protected power transfer to multiple amplifiers (up to four), and who wants a clean, high-profile look to their installation.

Connect a power cable from your battery to the set-screw input — the Power Ring® input accepts any gauge cable. Then run power cables and ground cables from up to four amplifiers to the compact, machined-brass block. The positive and negative outputs accept 4-gauge or 8-gauge cables. Finally, run a single ground wire (any gauge into the Power Ring® input) out to a bolt on your chassis, or back to the negative terminal on your battery.

The Combo Fused distribution block has a highly-conductive, corrosion-resistant Diamond Plate Nickel finish with gold details for premium power transfer with minimal voltage loss, and show-quality appearance. (You will need to purchase separately AGU fuses for your amplifiers, as well as a pair of power rings.)

  • dimensions: 6-5/16"W x 3-1/4"D x 1-1/4"H
  • Lifetime warranty

Great value

Written By John C, Charleston SC on Wednesday, August 22, 2007

I installed this in no time flat. It's nice and solid and I have a few extra slots for whatever and don't have to worry about a new fuse or ground. I'm glad I didn't have to run an inline fuse to both of my amps. I didn't use this to ground the amps but it was still worth it on a tight budget.

Thank you Streetwires!!
