replace facotry amp or add another amp?
 
my 1998 bmw e38 rear sub deck is completely blown and i am removing them and replacing them with one 12 ich kicker that is rated at 150 watt rms. should i replace the oem amp with a new one or just add a second amp for just the subwoffer?

Factory amp is a must, if not your audio system will not work at all. This includes your radio unit. Speakers might work but depends on impedance of the speakers.

no you can change you factory amp out.. just look up wiring codes on e38.org they will show and tell you how to change it out... im doing it to mine soon... im changing the head unit to a pioneer appradio.. and either keepin factory amp or ungrading that.. hit me up if u need some help

use an OEM integrator like the PPI ENT-5B it has high level inputs for speakers & 3 RCA outs for front, mid & SUB. No need to mess with anything. Hook that up, run RCA's to amp hook up amp as normal.


DONE.

google "OEM integrator" & you will see what I mean. Installed many & have one in my Suburban,

you can do it that way too.. Its really up to what way you wanna go with it.. stock or aftermaket. most ppl say aftermarket cause more power and you can get newer nav system and better speakers

So what ur saying is keep everything the same but just wire the new sub ( 12" 150wattrms) to the oem amplifier? Im completely reomving the OEM sub deck so they wont be in use anymore but i dont kno if the stock amp is strong enough to power my sub.

and i might eventually use the stock enclosure in the rear window for the sub but for now its in a separate box in the back of the trunk. ill post a pic prob this weekend when its all in.
