Installation Description

Factory head unit and speakers were all upgraded. After bypassing the factory amp, I installed Sony's CDX-M8805X CD/MP3 Head Unit and an Infinity 610a Mono-Channel Sub-Amplifier. The two were wired with Tsunami's 4-gauge power wire and 8-Gauge speaker wire. The power connection made at the battery was topped off with a Tsunami digital LCD volt meter. The door speakers were upgraded to an Infinity Kappa Perfect 6.1 6.5" component system. The rear speakers were also swapped for Infinity 693.5i Kappa 3-way 6x9's. Two brand new Infinity Kappa 100.3 SE 10" subwoofers in a Q-Logic sealed enclosure were stuffed in the trunk and all topped off by a Tsunami 1.2 Farad power capacitor. I recently completed a custom trunk enclosure made with 3/4" MDF Fiber Board all padded and covered with black suede and brushed aluminum hardware. The false floor for the amp and power cap was a last minute addition but completed the installation quite nicely. Overall, the system completely blew me away after seeing and hearing it for the very first time.

Q&A Section

Why did you decide to upgrade your A/V system?
The factory system was okay for stock, but my car was begging for some serious power.

What's the first thing you show people about your installation?
The custom trunk enclosure I made myself.

Why did you choose these products?
My car came with an Infinity system from the factory. If a stock system could sound that good, I knew right away what brand to upgrade to.

What was the most difficult part of the installation?
The factory amplifier gave me the most trouble when I tried to bypass it.

What plans, if any, do you have for future upgrades?
My next system upgrades will be another Infinity amp and Tsunami Power cap. I think a 3-channel amp for the interior speakers to give some much needed power to the components.

This unit without button or knobs disappears when turned off.

    If I wanted to swap out the factory head unit could I just use the mounting brackets off the factory ?

    Bruce, unfortunately, we don't carry a steering wheel adapter that works with your vehicle.

    Are the steering wheel controls still able to work? I have a 2004 diamante vrx and the metra axxess or PAC interfaces will not work when changing too an aftermarket radio!!! Any pointers??
