The amp is located near the firewall just above the brake pedal. It has two connectors plugged in - one white and one blue.

The "spec" is 35 watts per speaker times 10 speakers = 350 watts. However, the fuse is 20 amp. Given that most devices would be fused at approx. twice peak load the amp can not produce at max more than 120 watts. My ear says the RMS output would be 5 or 6 watts per channel plus 10 or so allotted to the woofer. The speakers are high efficiency 2 ohm and are rated at 35 watts max.

If the factory speakers are replaced with 4 ohm semi good quality speakers one will notice a definite flattening of volume control response ie, increase the volume to about half way and after that increasing the volume setting yields very little increase in sound output. Typical for an underpowered system.
