Will my clarion remote fit other head units? Would I have to modify the wireing? I would like to get a unit with higher voltage output. Any sugestions?

No Your Clarion Remot Will not work with any other Units Get a "Pre-amp" It will bump up your Output voltage as hig as 4-7 volts Im using the Rockford fosgate PA 200 they cost around $200 <BR>But There are plenty of other Pre amps out there <BR>
