Help Using 07 Bose Head Unit & Upgrading Speakers & Amp

[michaelinmech]

Can anyone help that has experience making this upgrade? I would like to retain my 07 Bose factory head unit and upgrade speakers and amp (if necessary) to achieve better overall sound. It would be preferred if the upgrade was easily reversible down the road for resale. I have an 07 Touring Roadster. I'm new to Z ownership and the Forum. Thank you for experienced advice.

I'm doing a similar upgrade to my Infinity G35 right now as I too don't like the Bose speaker sound. I've gone a little crazy with my upgrades, but the concept should be the same for you.

To keep your factory head unit in place, I believe you need a signal processor such as the Rockford Fosgate 3Sixty. This will take the outputs from your head unit, clean it up, tune it, separate it, whatever and then send the signal to an amplifier of your choice. Then the amplifier sends the signal to all of the speakers in your car. Of course you will want to replace the stock OEM speakers in your car with your choice of custom speaker components. If you want a subwoofer, add a subwoofer. If you want two amps get two.

The key I think is at minimum replacing the stock OEM speakers in the doors with better quality and then driving them with an amplifier. Again you need the signal processor (3Sixty) though to handle it all.

JL audio makes a similar unit called the cleansweep. However, these are not needed if you get an amp that can accept speaker-level (high) input.

I have a setup that uses the rear seat "subs" as the input for a pair of MTX subs, pushed by the 7801 amp. 1000x better than stock!!!

The Bose outputs are low level already so you are all set.
