Mobile Audio Systems & GPS

[smckenna03]

Hello All,

I am looking to replace a system of two amp's and one sub (10"), I am looking to replace the amps and the sub in either order, the sub is the cheaper one so I would most likely go that way first.

What id a crossover and a 2 channel over a 4 channel, i am not into car audio stuff so the more info the better.

Thanks,

Shawn
