Yes, Tod and I noticed this with the infinity system and the OEM-1.

However, we did notice that the empeg sounded BETTER than the stock system, just not as loud. Note that this is the OEM-1's problem, not the empeg's problem. The PAC OEM units are just tiny little amplifiers, and it simply isn't strong enough for the infinity system, at least not strong enough if you want it as loud as the factory system was.

On the good side, Tod can cap his volume at 0db and spin the knob to crank it, and not worry about distorting his speakers.

edit: I see I already said this earlier in the thread...
