if you buy a sub that is running over 1000RMS it goes alot louder than the speakers when fully bedded in i found that i needed to amp every speaker in the car so it would sit at the same volume as the sub i like my music loud and loads of base with the amps i was able to set the speakers up so they would not run any bass so it was just treble and was able them to go louder than the head unit then i set the sub up to run at the same volume it took a while then i had to buy a power cap to stop my lights flikering through out the car but its worth it
