Not only are you maintaining a much higher signal-to-noise ratio (a good thing) by using some other input method (USB/AUX/BT), but you can control the frequencies to each channel. With an aftermarket headunit (let's ignore the Scosche unit for a moment), you get better sound because you'll have more ability to control it. The amp is just amplifying a bad message. In your current setup with cassette adapter, you're introducing noise. The front speakers are easier.you just wire the input and output signal to the new crossover. You'd only do this with an aftermarket headunit, while running all speakers at 4Ω (typical for aftermarket radios). The wiring harness stays unplugged, and the amps collect dust. I'm familiar with it I have it in my truck.īypassing the amps is easy: the audio signal both enters and exits each amp, so you can just unplug its wiring harness and jump the input wires to the corresponding output wires. Sorry the answers are pretty 's because of the unknowns (specs) about the Bose system. Im still confused because I keep thinking no matter what is sent from the HU to the speakers, the amps adapt and just output the same amount of power as it did with the factory headunit.
#PATHFINDER AMP FULL#
If i were to just replace the headunit and use the Scosche adapter and not bypass the amps would i still get a significant increase in speaker sound quality, like closer to the speakers full potential. But back to what you said about bypassing, that seems like a huge task, how is that easy. Finally there is an amp in the rear cargo area powering just the rear speakers. One in each front door powering each front speaker. Second, I'm not sure if I have already told you this, I probable have but there are 2 amps in the front apparently. But as I said before the volume still dropped. Ok well I used JBL GX602 coaxial speakers for the rear doors and they are rated at 2 ohms which I was led to believe is the same as the amp. Out of curiosity, what speakers did you buy? Maybe there's something we can determine from their specs. Plus, with features like USB, AUX, and BT, those are 3 ways for music playback without degrading sound quality. I wouldn't even be surprised if a new headunit has a more powerful internal amp than the BOSE amp(s), so you might get better results just by bypassing it (which is easy to do). New speakers are only going to take the same stock signal and.well, hopefully expand on it if they have better frequency response, and integrated cross-overs. A new headunit with built-in EQ settings, custom EQs, a loudness setting, and adjustable ranges and cut-offs can liven up even the most basic speakers simply by filtering (HPF/LPF) frequencies and focusing sound where it belongs. IMO, the gains from changing the headunit on a stock system far exceed those of changing speakers on a stock system.
Not saying that's the case here, but a possibility. Perhaps it has a LPF that was suitable for stock speakers, but now you've added 2- or 3-ways that are being under-utilized. Without knowing the specs of the amp, though, it's hard to know what's going on. The BOSE system is exactly that: a system. You'd expect things to be plug-and-play, but when other non-standard components exist in a system, it could easily be apples and oranges. In all honestly, there are a few variables that can influence things. Not sure how new front speakers would react. A cassette adapter will definitely introduce noise and degrade audio quality. I have the unit, and quality seems fine to me (as fine as can be expected from stock speakers, anyway). I guess that's essentially what the Scosche unit does, though its description is a little vague. I think you're talking about line-out converter that takes a speaker level input and converts to a pre-amp output. You've got a couple things going on in there, so to tackle those first: Im wondering if when I replace the front speakers they will drop down in volume too just enough to where they match the back speakers so when I turn up the volume on the HU they both increase at the same level. Also I use a tape aux converter as an aux chord for my phone and its static anyways when I increase the volume a lot while using the tape aux. I also heard using an outline converter drops some of the quality and clarity of the sound is this true, I'm wondering if its that noticeable or not. Yes I have played with that but once I move the fader towards the rear speakers, the sound up front becomes less clear in quality and drops a tiny bit in volume each number I go in the rear speaker direction.
