E46 HK Sub Amp Wiring Diagram

Hey guys.

IM trying to install a LOC in my 05 E46 330i Sedan has the HK system.

I want to tap off the Sub amp on the rear deck, I have used the full range method from BSW in my M3, and I found that I couldn't turn the volume up very loud without losing output with my subwoofer.

anyone have any ideas?

Do not tap on the oem sub amp or rear deck speakers. If you want a clean signal, tap into the head unit outputs, which can be located going into the oem (main) amp on the left side of the trunk behind the liner. 4 twisted pairs with orange/brown grounds are coming from the front the blue/black and yellow/black are the rear channels.

Make sure the loc can handle a balanced-differential. Some amps can also handle a balanced-differential signal directly and do not need a loc. You probably didn't have good results because the adapter wasn't appropriate.

Can anyone clear this up? The last two people said different things. I tapped these wires from the factory harness leading to the oem amp and connected to a LOC and ran RCA's to my old alpine amp. The amp powers up but there is no sound from the sub...

EDIT! Search is my friend, looks like these wires are wrong

Actually both would work, but tapping into the rear speakers (wire colors above) is not the cleanest way to do it.

In your first post said you wanted to tap the rear deck speakers. That was the info I gave you. I also linked you to a post that had a detailed pin-out of the amp plug.

I tapped into my passenger vanity light circuit for signal wire for amp. Everything else could return to absolute stock.Couldnt think of a better circuit that wouldnt matter to me if fuse blew. Know of any better not in engine comp? I removed the 2 "subs" haha in pod and ran speaker signal wires from speaker connectors to high output converter( transforming speaker signal to rca outputs) then to amp. Had a rockford 800a2 powering a 12" boston g5 at 1 ohm and of course cooked amp by turning up converter controls too much and not stopping soon enough when could smell the overheating. Mmmm.

Your amp has speaker level inputs, which are superior to RCA. You could have avoided both frying your amp and purchasing that LOC. I also bought a LOC, and discovered that my JL JX500/1d amp also has Hi-level/speaker level inputs. Good thing I sold it on ebay for the same price I bought it for.

Ya i saw the input on side of amp but for some reason didnt want to look into buying the connector i prob threw out. I used a $35 LOC b4 and it wailed subs for years. Should have got connector. The LC2 i bought for $100 was too tricky for me to set both amp and LOC i guess. Whats best way to hold sub box solid! And look good? I used 1 ratchet strap over top of box to hooks but moved way too much driving hard
