2003 gm bose speaker system

  i have a 2003 silverado with the bose speaker system.  i have replaced my speakers with infinitys.  i would also like to add an amp to those speakers, in addition to the bose amp.   will it hurt any thing, to tap into the speaker wire coming out the bose amp, with a high/low convert.  then,  using rca's from there to connect to my four channel amp.  inturn, reconnecting to the speaker wires.

i know in another forum, i was told that connecting the 4 ohm infinity speakers to the 1 ohm bose system, would not hurt anything.  i was wondering if throwing my 4-channel mtx amp into the equation would cause any problems.

also,  would it be possible to tap into the speaker wires using a high/low convert like above, to add another amp and sub.

if you added another amp to that it f**k sh*t up

that is like adding two plugs on one appliance

it will either sound like sh*t cuz to much power or blow them up cuz some f**ked up wiring

don't do it

thanks,

that's what I thought about the sub.  Just the damn thing is hard to get to.

thanks
