my friend got all this free car audio stuff and we went to put it in. it is awful equipment, but its free and he has no money.

the hu is alpine cda 9811 i think

some awful pyramid power amp, 4 channel

2 12" alpine type e's

we hooked everything up, but the subs didnt work. he had 1 set of rca's, so we ran 1 sub of channel 1, and the other off channel 2. what could the problem be?

 
yea the led is on. its getting power. im wondering if its an rca cable...

the cable we used was a wite and red cable that look like rca's, but arent really. one was torn and we taped it back together. could that be it?

 
so you have the subwoofer level channel to one side bridged channels 1\2 to sub1, and the front or rear rca channel to channel 3\4 and briged them to sub2?

get a Y splitter that takes 2 racs and converts to 4, and plug them into both channels.

but the amp is prolly broken, or you wired it to somthing like 2ohm that it cant support. maybe its not bridgeable, and when you bridged channel 1\2 & 3\4 it fried instantly.

go get a cheap mono amp stable at 2ohms (i suppose they are svc4 on the subs) and bridge the subs to 2ohms (parallel?)

that should fix it (if the amp is broken that is - it might be the wiring or the subs, or the HU has broken pre-outs, maybe your RCAS are shot, what if your remote wire is broke\cut?)

could be many problems. i would look at the wires first. espically how the subs are wired. try and hook the subwoofer level RCA to channel 1\2 and just hook one sub up to JUST channel 1. NOT bridged.

just troubleshoot.

 
no we didnt bridge it at all. i mean, we ran 1 sub where 1 speaker should be, and another where another speaker should be. no bridging.

so we have 2 open speaker channels.

and he has no money at all. i mean like not a cent to his name.
