y adapter needed

[CHUCKmfnNORRIS 10+ year member]

the owners manual for my mono amp says to use a y adapter to split a single one of the rca's to go into the two inputs on the amp. is it needed or can i just plug the two in without using the splitter? the local audio shop said it isn't needed and it will give a stronger signal to the amp, is he correct?

You'll be fine without it.

Not sure what make or model is your amplifier, but for my JBL BP1200.1 there is a 4 channel input for a mono output. Apparently this amplifier uses a differential type input so the input won't be sensitive to front-to-rear fader position. Use of this feature requires that all four inputs are connected to the source unit as labeled on the amplifier (front, rear, right and left).

In summary, if you have a strong input rca signal then your amplifier should be able to produce full power with only 2 channel input. If you have a weak rca signal, use the Y-splitter. The gain settings are different with Y-splitters and without.

the amp is a mb quart dsc 1500.1d, the directions do say to split just one of the rca's to plug into the two rca inputs, and the rca connectors on the amp are colored black and not white and red.

you dont need the splitter with that, i never ran one on mine and it played perfectly, also i have seen a couple bench tests where those have been clamped around 1800 at 1 ohm.

my headunit has a designated set of rca outputs for the sub so its a mono signal from the headunit.

youll be just fine, just plug the rcas in, it doesnt matter which goes to which with subs.
