The "can you" question is a complex one. Yes, one CAN install the Alpine amplifier as a replacement for the Bose amplifier, but it will likely result in a poor outcome. I say that because the Bose amplifier is more than an amp: it has electronic crossovers that shape which frequencies that are...

Your response let me know I should have been a bit clearer on the "balanced differential" inputs. What I'm attempting to clarify is that if the aftermarket amplifier has this type of input, the amp doesn't need dedicated "speaker-level" inputs; it can receive either line-level or speaker-level...

You will. That filtering happens in the Bose amplifier, so because you'll be sending the speakers a full-range signal, filtering is needed. I'd look at a 300Hz filter as a starting point. Know, too, that the Bose amp has equalization that's speaker and car-specific, which you'll also not have by...

To chime in on what is a very frequent topic: the use of a line-output converter (the AudioControl LC6 is mentioned frequently): these are NOT needed IF the aftermarket amplifier has "balanced differential" RCA inputs. The Mazda head unit's speaker wires can be connected directly into the...

If you really wanted to do it, you could install the Bose speakers, but you'd need to install the Bose amplifier as well. And there'll be quite a bit of complex wiring required because the speaker cabling is different between the two models. Candidly, the benefits would not be worth the effort...

The Bose amplifier will handle higher impedance speakers without problems. The higher "load" means the amplifier will deliver less electrical current, rather than more. It's only when a speaker with an impedance lower than what the amplifier is designed for is paired with that amp that problems...

All, Does anyone know if the spare tire well will hold an 18" x 4" spare? There's about 1.5" gap between the OEM 17" x 4" tire and the surrounding foam tool support structure, so it looks like the area has enough room. Of course, I realize this is something of out-of-the-ordinary question, but...

I second that request.

As to the question of whether the head unit is different than the non-Bose head unit, it is. The head unit in the BOSE system has pre-amp level outputs (think RCA connections) that feed a low-level signal into the amplifier mounted just above the passenger kick panel. Of course, the CX5 speaker...

The center speaker can be put to use in a variety of ways. If you were to install an aftermarket processor such as the JBL MS-8, to get optimal performance from the processor, you'd need a center speaker. You could also make use of it with, for example, an AudioControl ESP-3 or the amplified...

Yes, the amplifier is in the passenger foot well just above the kick panel. There aren't any adjustments on the amplifier, which makes sense because the system was designed with known signal levels between the head unit and the amplifier. If you're looking to add a subwoofer, you can tap the...

One additional thing: the D-pillar speakers are wired in parallel, making them the same channel. So, technically speaking, Centerpoint is actually a 4-channel system (Left, Center, Right and Rear). There is no ".1" channel because the system doesn't have a subwoofer.

To expand on IgoZoom's response, Centerpoint uses the D-pillar speakers as the "surround" speakers, and uses the front Left, Center and Right speakers for those signals. The rear door Left and Right speakers carry the same signal as the front Left and Right speakers, though at a very reduced...
