Hey there -
The Honda amp puts out 270 watts PEAK (not RMS):
4 x 50 watts peak (reality is 18 RMS @ 4 Ohms stereo) for the door speakers
1 x 70 watts peak (reality is 40 RMS at 2 Ohms mono) for the dual voice coil subwoofer
So in reality it's a 112 watt system.
Not very funky at all.
The reason people are recommending highly efficient speakers to you is because high effiecency speakers simply do more with less power.
But if you use those speakers on a well amplified system they'll sound like hell because they are too sensitive - conversely, good speakers will sound terrible on poorly amplified systems because they are starving for the power to properly run them.
If you're on an extremely tight budget, get really sensitive and highly efficent speakers only.
If you can spend a little more, upgrade the head unit too and wire the extra power from the head unit into the amp.
And if you can spend more than that, do all of the above - and add a good amplifier.
And if you want to go all out - again, do all of the above and add another amplifier and a subwoofer.
This was all probably too much info - but I'm feeling verbose today.
