Metra Premium Integral Amp Harness Mates Perfectly
Review by LexusOwner
Install (5 star for easy)
Harness mates perfectly. Comes with 4 RCA plugs to connect to the 2 front and 2 rear pre-amp outputs of the new radio. Does not come with the RCA plugs for connection to the sub-woofer and that is because Lexus for the SC 1992-1999 model years does not power and take inputs from the radio directly for the sub-woofer...instead Lexus chose to tap the low freq from the rear speakers inside the old power amp and amplify/signal condition those low frequencies and port them directly to the sub-woofer. So, you will need to run two RCA lines from the new radio to the new amplifer (mono-block amp just for the sub-woofer) which you need to buy to power the sub-woofer. OR, do as I did and replace the old power amp with a new 5-channel power amp but you will still need to run two RCA lines for the sub-woofer from the radio to the new amp. So, this Metra harness works great to take care of the front and rear speakers but you will need to do some work to connect the sub-woofer...which is just the way Lexus spec'ed this car for the factory audio vendors (Nakamichi and Pioneer).(Posted on 10/7/2015)

It very easy to confuse your self and order the wrong Metra Wiring harness.
