[QUOTE="The Car Stereo Company, post: 1625004, member: 7124"] first off, nice job on your build. but have a question and some comments for you, and hopefully it helps. by no means am i saying anything but constructive criticism here. so dont take it wrong. define full volume. if you are at max on the head unit, you will definitely have distortion. if you set your max volume at 25 on the head unit, you are at roughtly 3/4 max of what the head unit will be. normally you get most output and least amount of distortion at 2/3 - 3/4 max volume. however its a little lower on these trucks. dont pay attention to rms power. it means nothing. there are some facts you havent considered with your amp rating. no amplifier is 100% efficient. if your 100 watt/channel amp is 92% efficient, then you are getting 92watts. now also figure in the length of power cable and size of power cable and you could be as low as 85watts. also, (to a certain extent) more power is better. it gives you the dynamic headroom to make sure you are giving the speaker the power it needs to play. for example, i have the focal 165wx-p in my truck. they are rated for 135 watts. i am running active so the tweeter and door woofer both get 200 watts a piece. so 400 watts. now my amp is a class a/b amp (mosconi as200.4) and i believe is 89% efficient, so 178 watts/channel. l/0 ga power running to a distribution block to a 1.5ft 4ga run to the amp. so in reality im probably getting 170watts/channel. the reason i bring this up is that if you are hearing distortion at higher volumes, it could be because you arent supplying enough power to the speakers. a good way to test this is to get the song "dont know why" by nora jones. her voice will test even the most extravagent systems. you will hear her reach the high points in the song, and if you hear a fluttering type sound when she does, you should focus on the amp rather than the speakers. also, what are the crossover settings for the speakers?
