i want to put a pair of Infinity 150s on my boat and drive it with a car amp. I have a cass. deck, cd changer already installed, but the exisiting KLH speakers lack bass.

So, can i drive them (8ohm) with a system designed for car audio (4ohm)?

Do you shop the same for car amps as home amps? Wattage measured the same?

As always, i'm in search of better sound.
