Hi, I got a LC 4-800 amp which i can high pass the underseat subs. Is there anyway of low passing it too (i.e. band pass) so its only plays 50hz to 150hz.

is it possible, would i need the D4.800? would these work??

Nope unfortunately not band passable. The 6.1200 can. I assume you're trying to keep it from getting frequencies below what it can reproduce? If it's a factory head unit you probably aren't getting much at all below 50hz

Channel 3&4 is what you need to use for low passing the subs. But it does not have a SSF. Do you need one? Do you have sealed or ported subs?

hi , I am trying to band-pass my underseat woofers. so I have set the high pass at c70hz, but I also want to low pass it at around 150hz to 180hz?

to be fair, would the HK amp from BMW have a DSP in it and would naturally cut off the EQ at around 180hz to 200hz anyway? i just don't want the HK Amp to play anything silly like 1000hz on underseat woofers and would make the voice voicals coming from floor if you know what i mean. just want mid-bass from the underseat woofers.

equally would the woofers naturally tail off anyway and therefore would naturally cut off at a certain hz range? its an Audio Development Neo 800 woofer
