The first part, as with most installs was the head-unit. As the standard Volvo radios in the C/S/V70's are a double-din unit an extra compartment had to be bought to fill the space, which can be seen below. The Pioneer outer cage fitted straight into the top section and the extra compartment just pushed in. An adaptor plug was used to fit the head-unit into the wiring loom of the car without having to cut any wires.

The main aim of the project was to create a sound system with loads of power (together with bass!!) but still be discrete and out of sight of thieving scum-bags. The speakers fit perfectly into the standard speaker holes and unless pointed out they don't stand out at all. For the rear fill I used the new Pioneer E-motion power blade speakers and as the TS-E2095 fit perfectly into the shelf, no modifications were required, despite being 8" they still are very discrete and out of sight.

In the boot is where most of the action is. The only access is by dropping the rear seats as there isn't anything visible from the boot. There are two GM-X944 class A amps, one powering the front components and the shelf speakers. The second amp is powering the two 12 subs. These are housed in a double custom vented box. There are three RCA leads running from the head-unit (front, rear and sub outputs). This gives maximum controllability from both the amps and the head-unit.

The power is delivered from a 100 Amp alternator and Optima Yellow top battery, through 4 Ga power cable, fused under the bonnet and fed to a 1 farad power cap. From there it goes to a fused distribution block and on to the amps, the whole electrical system uses gold-plated terminals including battery terminals, fuses and all cable terminals. Despite all this power there is still insufficient power supply to meet demand when the head-unit is cranked up on a bassy track. When the bass notes hit the power is in very short supply which tends to make the headlights and inertia illumination dim.
