Hello everyone, we’re getting back to the beginner questions. Check see my profile for my post from a few days ago.
I am planning to install an 8-inch slim/underseat subwoofer with an integrated amplifier. You may choose between 120 and 150w RMS (peak power is irrelevant, I think), with one option rated at 1500w.
I think this is 4 gauge wire going from the 12v positive terminal to the battery with a fuse, and it’s connected to my four-channel 800w amplifier that powers the front and back speakers.
Can I utilize the present wiring to power both my current amp and my new subwoofer with its own amp? I know it’s best to install a separate wire line to the battery for 12v power, but is it possible?
Much obliged

A distribution block would be ideal. This one is very pleasant to use; I’ve used it several times.

For both pieces of machinery, 4 Gauge ought to enough. Typically, it can handle about 130A (1300W), however this might vary according on the wire’s quality. Make sure the wires are properly fused and connected, and then put a distribution block on the current wire to provide another short run across to the powered sub. While you’re doing it, sort the wires so you can avoid shorts, make sure nothing gets twisted, and lessen the likelihood of noise interference.

It seems like the fundamental circuit is as follows: from the battery to the fuse, then a 4-gauge wire to the distribution block, and finally, two 4-gauge wires to each amp, each of which has its own fuse?

A fuse safeguards the wire. You should check that your distribution block is compatible with the wire size that your powered sub utilizes, which is likely 10 to 8 gauge. If it doesn’t work, you may need to find another distro or junction point to reduce its size. A separate, lower-amperage fuse will be necessary to safeguard that wire if its gauge is just 10 or 8 ohms.

Even if it doesn’t create any problems, I would be concerned about the protruding cable from the battery terminal.

The wire with the brown connector? That is for the seatbelt sensor that connects to the seat which is taken out here

Huh, the more you know! Lol.
