16 chip gainclone wiring

Matttcattt · 18th July 2003, 08:28 PM

i need some advice on the wiring of my 6 channel car gainclone using 16 chips. it will have 2x parrelleled and bridged, and 4x bridged. i have attached an image of the amp. should i have a star +v, and star-v? how should i run the signal connections? the red boxes are power, blue is signal, green it speaker out, yellow are the chips, and grey is the heatsink.

if people did not understand the question, i would like advice about where is should run the wires. i was thinking of running 4 solid wires from the front to the back (one above each row of chips) and running all the wires along these, dropping wires down to the chips. i then thought that having signal, power and output wires running parellel may cause a problem. any help is appreiciated.

when he says: "4) Starwire the positive and negative PSU lines to the chips using ideally twisted pairs of reasonably heavy wire, do NOT buswire the +V and -V lines." does he mean have a star +v and -v, and not to daisychain the chips, or the complete oposite?

NO buswiring/daysychaining of the V+/V- lines. ALL grounds meet at ONE point.

ok, i will need +v, grounf, and -v stars. how should i run the signal and output wires? should i run all the cables to the sides of the case? power and output on one side, and signal on the other?

That sounds like a good plan. Have you read the twisting thread? Also; shielded signal cables (coax) helps alot.

yes, i have, but i'll read it again anyway.

Hi,
I was planning a gainclone for the car but the +- PSU seems prohibitive...What is your solution?
