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.

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:

Rockford Fosgate PRIME R150X2:

Or perhaps:

Rockford Fosgate Punch P300X2

Rockford Fosgate Punch P400-2

Thoughts?

Boy...I'm starting to confuse myself... :shakes head:

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

:confused:

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? :confused:

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

Nice job on the install, looks clean. :tup:
I'll leave Matt to answer your front speaker question. :icon14:

If you tap into the speaker level outputs of the bose amp, you will only get highs or lows depending on which set you tap into. The reason is the bose amp splits the signal before going out to the speakers.

So instead of trying to sum multiple signals, tap into the low level signal going into the bose amp. This will give you a full signal with everything from highs to lows.

Thanks Matt....as usual ;)

So basically I can disconnect the wires from the bass output of the Bose that I tapped that I have going to the LOC (for sub amp) and replace them on the LOC with the low levels that would be going into the Bose and this will be good for both amps (high & lows)? Then I can completely remove the Bose amp? I wasn't sure if the frequency limiting was at the HU or the Bose amp.

Yes you can just use the low level full signal, I am not sure about removing the bose amp as I think some things go through it such as volume and a few steering wheel controls (BT phone)

Matt...you know this was coming...ha...ha... :tiphat: :

I haven't looked at the wiring diagram yet, so do you know off hand which low level wires going into the Bose amp to connect to the L & R (+ & -) inputs on the LOC?

:bowrofl:

PS: I think I'm going to go ahead and order the Polk Audio DXi6500 and FOSGATE P400-2 to power them along with a set of base speaker mounts and Zenclosure spacers. Should finish it off...

I looked at the wiring diagram, and I might just be able to remove the amp. I saw that the Nav voice and BT go from the HU to the front speakers. So, if I'm snipping the front speaker wires before the Bose amp and connect to my LOC like planned, then I'm hoping the Nav voice (which I don't use) and BT will continue to the speakers. Unless for some reason they are processed at the Bose amp. I didn't see anything else going through the Bose amp.

I received my Polk Audio components and Fosgate amp along with an 0 gauge amp kit, distribution block (for the 2 amps) and some new 12 gauge speaker wire. Nissan just called to notify me that my speaker brackets are in. Now I know what I'll be doing this weekend ;)
