Hey. If you don't care about budget then the new JL Audio 450/4 is perfect for ya. You can bridge channel 1&2 for the sub, 300W (150wx2), and channel 3&4 75Wx2 for your front component speakers.
I already installed this amp for my 03 Accord V6 EX Sedan with all Boston Pro Series speakers, no sub. JL Audio makes very good amps though they are more expensive than other brands.
Good luck!
