Well for my chevy s10. There is no other place to put a computer with out heavy modding. I have no back seats so no one will be kicking the system. Plus the seat is as far back as it will go since i have a speaker box behind me. So its not moving anywhere. Ive had an amp under the seat since 98. The carputer comes and goes

I will probably end up putting it under the seat just like the amp.

no place else to put it.
