I have opened up an older infinity amp out of a Jeep Grand Cherokee and a couple of Honda/Acura premium sound amps. What they all have in common is that they don’t have an onboard power supply to step up the rail voltage for true high watt outputs. They also use common 4 channel amp chips that have 1% thd rating of around 20 watts per channel (the limit possible with the nominal 12v provided by the car). The three chips in that bose amp mean it has a potential 12 channels. Every speaker in the car, including tweeters, gets its own channel and subwoofers get two channels bridged on the board. In my Accord’s case, it had two chips driving 4 speakers, two tweeters, and one sub. According to the chip specs, it was a 180 watt system but Honda advertised it as 360 watts. The active equalization and crossovers on the amps are what helps them sound ok for their size.
a speaker that is 94dB sensitive will put out 94dB at 1W. Thats 100dB at 4W. Most people prob listen at 70dB which would be less than 0.004W An $800 LC-6.1200 is 125wpc. For it to be twice as loud (+10dB) it would need to be 10x as powerful. 125 vs 12.5 (In reality I suspect it is at least 10x as powerful as the stock bose)
Newer Bose amps apply a horrific response filter to the signal and make a huge mess. I'd love to put one of these amps on the bench and see if it is possible to locate an unmolested signal to jail break; instead of having to cope with the reasulting mess that comes out the amplifier pins.
Where did you get the wiring diagram for this amp, I have a 11 impala with bose and want to upgrade speakers and aftermarket amp, I would love just use the wiring already in car since bose amp is in trunk, my amp/plugs are identical to one in video
Is there a harness that you can get that hooks up to a new amp to mount in the factory location? I’ve got an 04 Silverado with Bose and am lost on how to actually swap out the amp lol
amp looks identical to the 10 speaker system’s in 2010ish mazda 3’s. ~240 watt system and supposedly 2ohm. still a mystery to a lot of us in the community. im here cause mine finally blew and was just silence w/ radio, bt and the door chimes etc
I have a complete Set of bose amp, 6 speakers and 2twitters and 1mid speaker of Nissan Altima SL 2017 and I want to install it in some other car as it sound amazing in Altima. Can you help in wiring
My 2007 Escalade has the Bose system. Every 25 seconds the radio/cd sound gets interrupted. With the key off and door open or closed the speakers give a thump thump thump every so often but I have not timed that occurrence. There has also been static battery drain and the battery will be dead in three to four days. I’ve pulled the AMP Fuse because I believe it’s causing the issues. There is no interior sound of any kind (no chime, back up warning either). Can you do a video talking more in-depth about the installation of aftermarket stereo and amp with required components to retain all sounds?
Did taking it out cause any negative issues with chime or any other notifications that run through the radio. Or is that just running the speakers. I have an 07 that I took factory HU out of so I already have the PAC device that runs my chimes. Just not sure what all the amp runs in these vehicles.
If I have removed the amp out of my Acadia, which of course the amp that was removed does not work. But I have a replacement amp out of another vehicle, how exactly could I test that amp with a multimeter?
I have a 2004 Tahoe and the sound to the speakers and the ding ding cuts on and off and I read it’s the amp do you know anything about this I went to buy one and ther almost $500
Hello my brother. I own an amplifier BOSE and I want to put it in my car with speakers, but I don't know what each of its electrical wires does. Could you please help me? Give me your number to contact you on WhatsApp and I will send you the enlarged picture and direct us to the correct wire link.
you didn't say if you replaced the head unit? if you kept the HU, i would be interested why you opted to opted to remove the bose amp instead of taking advantage of a strong signal into a DSP (like a bit nove, etc) then to the whichever amp(s) you chose. this is how my regal is setup and i'm wondering if the loss of signal strength offsets the gains of being rid of bose in my car once and for all. what i would like to find is an awesome pre-amp to get a strong signal from the factory radio (can't swap radio in my buick) to the DSP.

I wish I could put this on the dyno and oscilloscope
@@stereomojo I set the EQ flat and ran the outputs from a 21 GM Bose amp into a calibrated input and the result was 🤮. Far worse than I anticipated.

I have the plugs I'm trying to load my 2 6x9s in the back dash and 2 6.5s I need to know how to wire it to speakers and to car
Quality doesn't have to be packed with components My PBR 400.4 d doesn't have that many components

Pode ser a bobina em curto circuito de algum falante de porta.
Verifique todos os falantes.
What did you put in it's place
A D4S JP84

will a tahoe amplifier work in sliverado ? that’s bose stock and need replacement

400 watts
I have one from my Cadillac and I hate it with a passion.
lol. I hear ya!
Dear plz where location this amp in gmc envoy 2006 ??
Idk about the Envoy, but ours was under the front console. This was a 2008 Tahoe

I have a question for you if you have time about regal gs bose systems
