I have a 2006 BMW 530i American spec. I want to install my 1200w mono amp and 10" subwoofer.
there is a 5pin high level input wires coming out the back of the amp,....how do I connect the high level input wires to the factory amp wires? Which wires do I connect them to? Please be very specific because I obviously have NO clue what I'm doing. I don't have an Loc or high low adapter.

 

you need to get a LOC to install it properly. if you have no clue, id leave it up to a shop. dont wanna mess anything up

 

I never use the high input on apps so I dont know how well that works but this is what I did to my 525i

in the left side of my truck there is the stock amp. there are 4 slim wires together those are the inputs the a slim blue and white that's the remote and the 4 fat cables to the right and left of the remote one pair has a red and white cable and the other a brown and white cable (I think) those are your sub out connections. and the 2 fat ones on the opposite end of the 4 slim ones that's your ground and power.

from the stock amp I cut the sub out cables and connected the harness side to my high to low converter. from there a pair of rca to an epicenter another pair of rca to boss riot monoblock. a cable from +battery to amp and chase ground to amp. tap into the slim blue cable to the remote. now the sub out cables I cut from the harness that go to the subs under the seats I connected those to my monoblock in parallel mode. meaning + to + and - to - and Vuala no sub box needed the ones under the seat did just fine. maybe will upgrade them in the future
