Hey, i've just bought a pair of sony XS-F1035 10cm speakers for the front (3-way coaxial, 140W peak power, 30W rated power), and some kenwood KFC-E6950 6x9s for the back (5 way 500W peak, 90W rated), along with a sony headunit that offers 4x52W output. Now, i'm sure i will need an amp to make the speakers sound good right? but i know nothing about them! if someone could give me some advice that'd be great! Thanks, james.
