OK, when I step on the brake, the radio shuts off, then turns back on. This just started this afternoon, and it seems to be intermittent. The head unit, amp and sub tube were installed by the previous owner, and I don't know enough (or anything at all, really) about the installation to even know where to begin looking. Any advice?

I would pull the dash apart and see if radio was hardwired in or installed using correct harness adapters. Thats where Id start

 

A radio wire is possibly touching the wire for the Brake Lights.
Before you tear your dash apart look around the brake pedal for any wires that are touching.

 

Thanks. Checked around the brake pedal, didn't see any wires. I'm going to have a new head unit installed anyway, so perhaps that will solve the problem without me tearing the dash apart and screwing it up.

I'd just rewire the deal. The stock harness is crap anyway. Remove the crap the previous owner slammed in there and run your own.

How's your voltage. Just a shot but when my alt. was failing it would shut off the radio when the voltage dropped. And having a sub you could be pulling too much for the ol' girl.

 

Could be. The alt. should be OK, it's relatively new, but I'll check it. I'm probably going to remove the sub anyway, so that may eliminate the problem as well.

If you recently replaced your alternator.. it was probably because your car wouldn't start one day...which means that your battery was dead... and knowing RX owners they dont bother fixing things until they happen many times which means that you probably killed your battery a few times… I would say you probably have a battery with a few burnt cells… get it tested and replace if it is bad…make sure they test it twice, your local parts store should be able to do this free of charge

 

some one probalby used those junk crimpe connectors
why dont people just solder... sheesh...
take it out, and solder it...

 

Bad alt... not a connection issue. A voltage issue.

 

dude, we know your troubled. check your fuse block, see if the "other" owner hard wired it to the fuse block, then take apart your consol and look at the wire job, if it looks like wire nuts and duck tape, then look at the FSM and find the original wires, go from there and rewire the radiop, but keep an eye on your voltage, if it drops below 12 volts when running then you have a problem and need to start praying cause im not good at wiring, but im trying to help. make sure your battery is good, is fully charged and stays fully charged, then check your altyernator, then go into the radios wiring, remember to always start simple.
