Can anyone tell me the dimensions of the factory amp in a 2005 Lexus SC 430. I'm looking to replace it with a five channel and was wondering about the fit.

Also, would disconnecting the amp stop anything else in the vehicle from working?

Thanks

 

some controls at the steering wheel. when you change the Amp you go from 8 ohm speaker front and side and 16 ohm sub. all replacement Amp are 4 ohms

 

Question not sure you can help me. If i running two 10 inch subs equaling 1000 watts would I need to run a capacitor or is the alternator strong enough for the amp and two 10"?

 

you dont need a capacitor, just make sure you have at least 4 gauge power and ground wires and do the big 3.
