Can I run power and ground in series?

[ccajun4real 10+ year member]

I am going to run three small amps for my system. 1 X JBL 180.2@4 ohms, 1 X JBL 150.1@ 2 ohms, and 1 X MTX 4122@ 4 ohms. Can I run the power lead and ground in series or do I need distribution blocks for this? Also can I run the remote lead in series? Thanks

use a distro block for the power... for the grounds just run a ground for each one... the remote lead you can do like that

sexxxy car btw!!

I'd use a distro block...

For three amps, I'd probably use a relay as well, could be a lot of current demands on your head unit.

You could just run another +wire from the batt and put a switch on it and run that to the 3 amps for the rem turn on.

What is a relay? Please excuse my ignorance. Thanks

Ended up getting 3 x gold 4 into 1 distro blocks. I can now start my project. Thanks for all the help fellas.

relay is a small switch with a magnet on the end of the switch, and an electromagnet also inside -- you can then use a 12V signal (to the small electromagent) to switch something on/off.

the idea is that the HU's remote lead is made for low current. 3 amps should be ok. but if you wanted to run fans or such from the remote line, you could use a relay. the remote line would attach to the electromagnet and switch on a higher-current 12V line for fans, ect...

other devices also work, but relays work at high currents, and are easy to use, and are self-contained.

you might wana have a shop wire your amps/relay to turn them on, i would not recomend doing it your self.
