Constant-power lead for '95 Corolla?
Hi,
I'm doing a simple head unit upgrade in my mother's '95 Corolla. She has the factory AM/FM Toyota radio currently. Anyway, the replacement radio is a new Panasonic, and like all HUs today, is a high-power one that needs a 15A constant power line from the battery. Clearly the tiny little radio in the Corolla now won't have a constant power line that can handle this kind of current. Now, I'm sure I could do something half-assed, but I like to do things right. So where in the Corolla can I most easily get a high-current constant-power line? Are there any spare, unused circuits in the fusebox I can tap into? Or, if I have to run a line to the battery myself, are there any grommets in the firewall that are particularly easy to snake wires through? Any experiences from Corolla installers would be appreciated! TIA, Jonathan |

Just buy a wiring harness, and use that. No need to run a new lead to the
battery for this. "Jonathan" wrote in message ... Hi, I'm doing a simple head unit upgrade in my mother's '95 Corolla. She has the factory AM/FM Toyota radio currently.

You don't think I need a dedicated lead, in order to get max. power out of
the internal amp? I mean I know it will work without it but the amp. will clip at high volume. Like I said, it's my mother's car, she won't crank the volume, I just want to do the job right. -Jonathan "mayhemkrew" wrote in message news:R2Gsd.140637$V41.2339@attbi_s52...

I install stereo's that output 52x4 (max) in cars all the time without any
problems. You'll be fine. "Jonathan" wrote in message ... You don't think I need a dedicated lead, in order to get max. power out of the internal amp?
