Just bought this throwback to the 90s brand new in the box. Now to see if it can run some subs all the instructions are hilarious showing a tapedeck.

Built before amps had crossovers in them it used to have to be plugged into a companion box to get low pass curiously it can run as a 3 channel with this Eq box. As my headunit has a sub-out i wouldn't mind betting it'll work and sound beautiful.

If it cant run them i have something else suitable but not as cool.

If anyone is keen on this its for sale pm me. Decided to only run 2 amps and i need to use my 4 channel for the application.

thread dredge, i couldnt find another doof doof/ICE thread in 15secs so using this one

I am putting some very basic small doof doofs in my note. I need to change the headunit from jap nav spec anyway (DMH A4450bt going in), so i have acquired a pioneer TS WX610A sub for the spare wheel well, and some low-mid 2way spec speakers for the doors TS F1740s, fed from a teeny little GM-D1400 amp. Should be nice sound for a small car fingers crossed

Anywho - i need power supplies to both the sub (inbuilt amp) and little amp, in days gone by i would have just pushed these two yellow cables through firewall and bolted/smooshed to positive terminal but figure there's possibly a nicer solution? Best terminal bus bar type product to either hook both on to or run a little lead in to a junction box of sorts? I'd rather not have yellow cables weaving through the engine bay - whats best bet for sheathing thats not corrugated split tubing?

chur, this stz? https://www.aliexpress.com/item/1005003887563443.html

what i'm referring to as a busbar at battery/junction box internally, seems to be known as a distribution block (my bad) - any thoughts on what's better - bring both amp connections to battery terminal, or just run a single lead into the car to a distribution block and from there out to the amps. In either case, I'm guessing best to run a fuse close to battery

If the amps run different sized wire, won't it be an issue if the fuse used at the battery is rated to more than what the smaller wire is? Maybe I wasted my time running amp + headunit as separate wires all the way to battery end. With a fuse on each of them rated accordingly. Or with the distro do you run individual fuses after the block and one at the battery end? My theory, right or wrong, was that a skinny wire will light up before a large fuse will trip, if the large fuse is protecting both wires. What say thee?

Amps normally have their own fuses on them, the fuse at the battery isn't to protect any of your audio gear, it's to protect the car if the power cable ever shorted out.

 

Edit: re-read your post, yeah you could run fuses between the distro block and each amp if you're stepping down gauge. 

Or fused block
