A non-fused power or ground distribution block from the Stinger HPM Series two 1/0GA or 4GA inputs, four 4GA or 8GA outputs, satin chrome finish, protective cover included. Suited to larger multi-amplifier installations.
The Stinger SHD21 is an HPM Series power or ground distribution block with two high-gauge inputs and four outputs designed for larger multi-amplifier builds where a single distribution point needs to service up to four separate amplifiers. It accepts two 1/0GA or 4GA inputs and provides four 4GA or 8GA outputs.
The satin chrome finish matches the SHD20 for consistent aesthetics across a build, and a protective cover is included. Non-fused main line fusing must be provided externally at the battery.

What is the difference between the SHD21 and the SHD20?
The SHD20 has one input and two outputs — suited to two-amplifier builds. The SHD21 has two inputs and four outputs — suited to larger four-amplifier builds or installations requiring more distribution points. Both share the satin chrome finish and non-fused design.
Why does this block have two inputs?
Two inputs allow two separate large-gauge power runs to be combined at the distribution point — for example, two separate battery or power runs feeding a single distribution block, which then splits to four amplifiers. This provides greater flexibility for complex multi-source builds.
Is fusing included?
No. The SHD21 is a non-fused distribution block. Fusing must be provided externally on each power run at the battery using appropriately rated ANL or MIDI fuse holders.
Can this block be used for ground distribution?
Yes. Like the SHD20, the SHD21 can be used on either the positive power or ground side of the installation.
What gauge wire is compatible with each port?
Inputs accept up to 1/0GA (1/0 AWG) wire. Outputs accept up to 4GA (4 AWG) wire. Use correctly sized ring terminals or crimped connectors to match the wire gauge being used.
