how much does the bp power option raise the rms on a 12" ssd?? would one need this option running 2 off a rf t10001bd 1633rms @ 1 ohm? what coil would be the best-regular, copper, or flat wind? daily driver (possibly a comp here n there for somethin to do but rarely), in trunk of an 00 impala, 2.5 cubes each tuned to around 38hz, i listen to most all music, lots of rap turned up loud, cuz its loud n low.

If you want "loud & low", you're tuned way too high.

^^^^^thanks for all that info . i would haffta say that, in my car atleast, playin rap music with a box tuned to 38hz is alot louder and a lot lower than lets say ummm rock or something else.

That's because the notes used in rap are, in general, lower in frequency and greater in amplitude than those used in rock music. Jim was saying that you're actually missing out on a lot of the low end because your box is tuned that high.

You will have a lower roll off point if tuned lower. The output will be less peaky, but I am not sure you are going to like that.
