How to add together a subwoofer amp to the X5 mill audio

Introduction

The bass is used to convey power & force and to requite the listener the fullness and depth necessary to really enjoy the music. When I bought my X5 the very first thing I noticed was that, although the audio components were of pretty loftier quality, there was a definite lack of lower bass. The sound system tin be easily improved by adding a subwoofer and a sub amp. In this certificate I explain how to connect a sub amp to the X5 stock amplifier equipped either with DSP or not DSP. I have described 3 different connector types that I have seen on X5�s stock amplifiers and explicate where to get the sub signal for each of them. This is to connect a subwoofer amplifier equipped with high level (speaker level) inputs. Loftier level inputs enable tapping into the speaker wires to feed a subwoofer amp. It is called high level because the signal has already been amplified every bit opposed to a low level signal (pre-amp level) which needs to be amplified before going to a speaker. If your amp only has low level inputs and you want to connect information technology equally explained here yous will need to add a line level adaptor earlier feeding the subwoofer amp. Connections to the manufactory wires are made using crimp & snap connectors similar the one shown in the pic below.

Powering the sub amp

In addition to feeding your subwoofer amp with the appropriate sub indicate input, the subwoofer amp volition need to be powered past a constant (+12v) direct from the battery, a proficient basis and a (+12v) remote 'plow-on'. You can get a good constant (+12V) from the power and basis betoken. The power and ground betoken is a plastic box (normally green) located near the spare tire nether the trunk floor. Y'all should detect several �empty� power taps that y'all can employ to ability your sub amp. Each available power tap has enough current chapters to ability your sub amp and is protected past a fuse. Picture 2 shows the (+12v) remote 'plough-on' source connector where I got the remote on/off +12v. I institute the connector (shown on the picture) somewhere nether the CD changer. I tested all the wires with a voltmeter and institute ane which worked with the ignition. Not sure if you will accept a similar connector in yours. Use a voltmeter to bank check which of the wires is a +12v connected to the ignition. To prevent whatsoever damage you should always employ a voltmeter and ohmmeter to double check all wirings earlier making the connections.

picture 2 Identifying the type of connector The very first affair to practise is to identify which type of connector you accept on your factory amp. To examine the connector remove the flashing (normally on the left side of the cargo expanse). The CD changer (if equipped) and factory amp are located in the lower part of the mounting brackets, plant behind the flashing. If your automobile is equipped with the CD changer yous volition have to remove it to accept full access to the manufactory amp connector. To look at the connector you must squirt it from the amp. This is done by sliding the connector with the assist of a tool such as a screwdriver for example. Picture show iii beneath shows my X5 factory DSP amp, cd changer and the added sub amp.

Type of Connectors

1) if you have an X5 with premium sounds and DSP: You should be able to count 15 pins in this connector even if all pins are not wired. On this connector you can tap into pin # 7 and 14 to feed your high level (Speaker level) subwoofer amp inputs. You should notice 2 cables thicker than the others. These are pin #8 (power +12v) and pin #15 (basis). That should help locate pin #7 and pin #14.

Motion-picture show four below shows the 15 pins connector on my X5 with ii reddish snap connectors connected to pins# 7 and fourteen and two added wires (blue and white) which become to my subwoofer mono amp high level input. If you have a 2 channels amp instead of a mono amp then verify that it is bridgeable which means that you lot can span the two channels into ane to feed a subwoofer. Not all amps are bridgeable. This should exist clearly specified in the documentation of the amplifier. As well be aware that by bridging there will be twice the ability on one speaker. The bridged rating is usually listed with the spec of the amp. If you accept a ii aqueduct amp you can feed your amp�s high inputs from pin # seven(-)/14(+) for right speaker and 10(-)/ii(+) for left speaker. I simply used seven/14 in my case considering I used a mono channel amp

2) X5 non premium (no DSP): You lot should run into 12 pins in this connector even if all pins are non wired. Picture 5 beneath shows the wiring of this connector. Yous can tap into pivot # five and 6 or eleven and 12 to feed the high level (speaker level) inputs of your subwoofer amp. As explained in the previous section if y'all have a two channel bridgeable sub amp yous will be able to feed your amp�south high inputs from pin# 6(-)/five(+) for right speaker and 12(-) /xi(+) for left speaker.

Picture 5 3) Other Harman/Kardon equipped X5: After ejecting the connector you lot should now see 2 connectors next, a gray one and a black one. The pins are numbered from 1 to 13 on the gray connector and from 22 to 34 on the black ane. The pictures 6 and 7 beneath show the 2 connectors. On this connector Pivot #1 (-) and #2 (+) are for left rear woofer and pin #24 (-) and #25 (+) are for correct rear woofer.

You can tap into #24 and #25 to feed the high level inputs of your subwoofer amp every bit shown in the moving-picture show eight below.
Flick eight If you have a 2 channels bridgeable sub amp you volition be able to feed your amp�s high inputs from pin# 24(-)/25(+) for correct speaker and one(-) /2(+) for left speaker.

Savor!!
