what you really need to keep an eye on is impedance. dont use speakers or wire them so the ohms is less than the amp can handle.

Just for the record, amps don't push speakers . . . They supply power. Power(watts)=E (volts) X I (current)
Class D amplifiers are now commonly used in cars - especially for sub amps (in home subs too btw). They don't require massive transformers.
You have to carefully match the power cables from battery to amp. Keep them short and follow the specs for the guage required to avoid arc welding in your car.
