to you too.

Guys:

I'll be wiring in my LC2i tomorrow as my amp should be arriving (box & sub the next day). Is it better to wire the LC2i on the sub output wires from the Bose amp or on the input side of the Bose amp before it goes in to it?

You had it right in your PM, sky blue and voilet 9 and 14 on the bose amp is the same 2 wires at the bose sub connector 1 and 2, tap into those 2 wires at either place.

Thank you for your question and interest in AudioControl. Where to tap in will depend on whether you have full range and how you want fade to affect your subwoofer. The LC2i does not require full range signal, it is an active line output converter and what goes in comes out. As far as using one pair from your sub output, that is fine. If your amp requires 2 channels at the input, you could y out either at the speaker level output from your amp or at the RCA output from the LC2i. If you can run fully mono, then just stick with the left side on the LC2i, which is where the GTO Signal Sense lives.

Mr Sparky:

Could you explain why you would need to connect to both left & right inputs on the LC2i? Your running a mono amp, so wouldn't all you need to do is connect to the left side of the LC2i? Am I missing something in the above description

I guess if your amp has a left and right input then to get a left and right output of the LC2i you have to feed it a left and right signal. As the bose sub only has a mono feed then bridging it to both is how this is achieved. It was just a question I asked and that was his answer so I went with it! Obviously your feeding both channels with the same signal and it gets summed in the amp but my amp manual said it would have low output if you didn't feed both left and right inputs.That's why I asked him how to do this and his answer is above, so I went with it. Hope that makes sense!

Matt will probably jump in here at some point and correct me I'm sure.
Edit: His comment above should read" you could y out either at the speaker level output from your BOSE amp or at the ..................

RonRizz · 01-09-2013, 10:02 PM

I believe the reasoning behind his reply is that not all amplifiers sum the inputs, in which case, even though you are feeding it a mono signal, you will only have output on the right or left side (whichever you have connected at input) The simple solution is to feed both left and right inputs.
This is why he mentioned that you can sum the inputs OR the rca outputs on the lc2, but if you use the outputs to sum pre-amplifier, you need to use the left side input on the lc2 for signal sensing turn-on.

So it's best if I just Y off the + & - outputs on the Bose amp into the left & right inputs on the LC2i and then RCA L & R from LC2i into my Fosgate R500-1D, basically like described from sparky & AC....

I just get confused as I've never installed an LOC before and for some reason it's throwing me off a bit

sparky · 01-09-2013, 11:10 PM

You got it right!

pfdaxe · 01-21-2013, 08:15 AM

Finally got more base

Thank you Sparky & bigaudiofanat for tech assistance

This set-up is night & day compared to OEM Bose sub and well worth it. Here are some pics and opinions:

Rockford Fosgate R500-1D Mono Sub Amp, Audiocontrol LC2i LOC, 4 Gauge Fosgate Amp kit mounted behind drivers seat:

Corregated cut for box to sit a bit lower. FYI: The cargo cover clip will STILL hit top of box:

Relocated tools for access. I trimmed some of the foam so tools would fit snug:

Wicked CAS Corner Box , JL Audio 10W3v3-2 Sub & JL Grill. I mounted the box with a couple of self-tapping screws:

Very clean, nice install. I've wanted to integrate an aftermarket sub into my Bose system for a while now, but have always struggled to wrap my head around how to do it. This thread has finally made things clear enough for me feel comfortable taking on the task.

RonRizz · 01-21-2013, 01:13 PM

Looks good

Hey guys: I'm back with more questions. I'm thinking about replacing my fronts with a set of 6.5 components (the roll-off of the highs starting to bug me a bit) . I know all about re-wiring which isn't really a big deal.

My question is more about the amp connection.

Do the front speaker output wires from the Bose amp send a full range signal? Right now I have the sub out wires from the Bose amp connected to the speaker input on the LC2i to send the base signal to the sub amp, but I cannot connect the front wires AND the sub wires to the LOC at the same time. So I was wondering if the fronts would provide enough signal for the amps that are for the sub and the second amp for the fronts? I spoke with Eric at AC and he said he wasn't sure if our vehicles had the full frequency or I'd have to install a second LC2i just for the main amp.

I guess I'm just looking for the easiest way to connect a second amp...

This is what I'm looking at:

Polk Audio DB6501 6.5-Inch 2-Way Component:

http://www.polkaudio.com/products/db6501

Rockford Fosgate PRIME R150X2:

http://www.rockfordfosgate.com/produ...?itemid=225201

Or perhaps:

Rockford Fosgate Punch P300X2

http://www.rockfordfosgate.com/produ...?itemid=120386

Rockford Fosgate Punch P400-2

http://www.rockfordfosgate.com/produ...?itemid=108228

Thoughts?

Boy...I'm starting to confuse myself...

bigaudiofanat · 01-29-2013, 03:21 PM

The front outputs do not carry a full range signal, the best way is to tap into the low level inputs going into the amp, this way you will have a full range signal to do whatever with.

If your going to amp your new speakers step up to either the DXI's from polk or alpine type R's

I only have the RCA inputs going into my amp from the bass output of the LOC, or are you talking about the wires from the HU going into the Bose amp?

Good call on the speakers. I really like the Polk DXi6500's and they're not much more
