i have an xtant 50x4 and i am going to run 2 chanels to my mb quart rsd216 and bridge the other 2 chanels to a sub. when bridged it will be 200x1. i need a sub recomendation. also where do i ground my sub if it is mounted under the floor in the glove box? plus any recomendations for some rear speakers that can run off a deck and still sound decent. the deck puts out 22 rms. thanks for the help

 

wow there is alot of variables going on here

i think you mean ground the amp, not the sub... just ground the amp to bare metal, any part of the chassis will work

I would buy one of the lower end mb quart 6.5in speakers for sound fill in the back (i recommend infinity, but might as well match the fronts)


get a 10" sub, 12" would be too big for 200watts

again i recommend infinity ....hehe sorry im biased.. but they are badass speakers
