Does anyone know if the audio out on a TV (RCA's) has approximately the same signal level as a car HU's audio out (RCA's)? Will I run into any problems by conecting the TV's RCA's to my car amp's RCA's ?

A review of TV specs may tell you that. However, most TV systems are very low voltage RCA systems. They probably max out near 1 volt.
Video was an indoor feature until DVD's came into the game a few years ago. Since there are few noise issues, HT units can operate on lower RCA signals w/o noise problems. My guess, the typical TV RCA's will net 0.75-1.0 volts on average. A car amp with sesitivity range > 250mV, should handle it.

I don't see any problem other then tripping over a very long rca going from the living room to the garage....

No long RCA cords. The car amps are in the living room.

OK. I hooked everything up and when I turned the TV on, the volume is too loud. Turned the TV volume down as far as it would go, turned the gains down as far as they would go. Still too loud. I just read the specs for the TV. It says it has fixed audio out. Is there any way to "adjust" the volume? Any ideas/suggestions?

are you coming straight from a TV or from a cable box, vcr, etc??

Straight from the TV into the amp.

Would this work?

with the gains on the amp all the way down, you should get almost nothing out. A fixed audio out will not allow you to adjust the volume on the tv.
never seen a toy like that. That would do the trick, but 12db is alot...

Would an RF modulator work? Connect the TV audio outs to the modulator, connect the modulator to the HU, and connect the HU to the amp/amps.
