unable to get 4 channels working

[vx-s_Man]

i have a 4 channel pioneer amp and i can only manage to get 2 channels working. the amp is running off the stock vx head unit. ive installed the hi-lo converter to turn the wires into rca outlets.just wondering if i need two hi-lo converters to make 4 channels work. ive also tried splitter wires and they arent making the amp into the 4 channel.any help would be appreciated

i think there might be a switch or setting on the amp, depending on the model, to set the channels so that channels 1/3 runo off the 1 input ans 2/4 run off the 2 input, but im not sure if its there on pioneers. If not, buy some RCA Y-splitters and use them on your hi-lo converters, so that there are 4 RCA's running into the amp

It probably has a 2 CHANNEL / 4 CHANNEL switch on the amp, as said above... Check that.

yer or it may say INPUT A or A-B, them being the channels.
