I connected a 8673135 Volvo amp to the SC-816 stereo in my 2000 V70. I had earlier changed out the speakers, (two pairs of cheapo Hertz K165) which sounded better, but the head unit sounded like it was working too hard. The bottom seemed to drop out as the volume when up. I got a 6 pin din cable and...

Good day. I have a 2000 V70XC. On the Rock Auto site, I see two different styles of head gaskets, from 3 makers. The difference is in the placement of the water passage holes.
