ok...im lazy and dont wanna pay to install the subs...

i just bought some kenwoods and a 920w amp pak with a box. since i have a b15 sentra se, there is a factory sub. can i just disconnect it and how would i set up the wiring the proper way without having to drill holes in my firewall?

can i just run the cord through the dash and under the floor carpet. also how do i get the frequency to my amp...do i really have to sauder/strip and tape together my speaker wires to get the frequency to the amp or is there an easier way? thanks.

leave the sub in connect it like a speaker
just run the cords thru a hole in the firewall thats already there. for instance the hole for the wiring harness.

actually what you should do is since the factory sub is a 6.5", and there is a spot for it on both sides, you should buy 4 6.5s and wire them all to a 4channel amp. that would be sick. or id bet with some careful cutting you could fit two 6x9s in the stock speaker housings and make it look clean as hell.

lol....im planning on setting it up to have each sub pushin like 460w @ 4 ohms....but i need to find somewhere that i can get two 2gauge wires that are like 17 ft long each to power the 2 amps. kinda gotta build my own amp kit kinda sorta. i did think of what u said before, but i diddnt really wanna get into customizing and drilling into it.
