Alittle aftermarket radio install help please.
 

Hey guys, I just installed an aftermarket MP3 player in my '92 LS400. Everything went pretty smooth for the most part. Actually, there are 2 things that I need help with. First off, Anyone know what the deal is with the power antenna? I was using a schematic I found on these forums awhile back and everything was right on the money as far as the power/acc/ground/speakers went. But when I hooked up the power antenna lead, I don't get anything when I turn the unit on or off. I metered the lead and it seems right. But nothing. Any ideas on why that would be?

Number 2, right now I have the sub completely disconnected. I just spliced into the power and speaker wires since this was on a bottom line no amp Pioneer unit. But the sub has me slightly confused. The stereo I bought has a sub out on there, so I was hoping there would be an easy way of converting it to work with the rca outs on the radio.

Any help at all would be greatly appreciated.
Thanks
