Yes, that'* what I would do.
just out of curiosity wouldnt getting a separate equalizer just fine tune it from the stock head units integral equalizer or does that become useless if the bose amp is removed? it doesnt make much sense to me how that would work
Many complain of OEM sound quality. Most times, the poor quality is due to a response curve that is not flat. Speakers have a resonant frequency and will be more efficient at that frequency. This causes a part of the audio spectrum to be louder than it should be. If this isn't allowed for in the design of the system, it can sound pretty bad. Speaker location, upholstery and interior shape can also affect the audio spectrum.
The Bose system is "tuned" to the car and speakers to eliminate this (or at least that'* the hype). Then there is no telling if Bose tailored the response curve to be flat or something THEY think you really want. Since the head units are the same for the Bose and Monsoon systems, it'* likely the amp that is "tuned".
If you are installing an aftermarket amplifier, it will not be tuned in this way. Plus, if you change the speakers, something else is different still. An equalizer gives you control over the audio spectrum. I have found by experience that an equalizer is the single most effective way to improve sound quality.
I will be installing equalizers for both front and rear. This is because the front and rear are intended to do different things. To simulate a concert, most of the music is in front of you. The wall in the back of the concert hall will reflect some of the music, so if you have speakers behind you, it simulates an additional dimension to the sound.
However, the sound that bounces off the back wall will not have the bright highs because they are easily absorbed in the room. Therefore you don't need the highs from the rear channels.
The rear deck of cars is suited for larger speakers than the front. This makes it ideal to generate your bass from there. Low frequencies are difficult to determine where they originate. So it doesn't sound funny to have the bass behind you because you can't tell.
Anyway, there are a number of products that provide this very thing to make an OEM system sound great. They are called OEM Audio Integration or something similar.
Sorry for the long winded post.
I hope this didn't get too involved.
