Well, you could get one of those RCA to OEM adaptors but it doesn't seem like it would be all that great. Unfortunately, even though it's a nice sound system, nothing is compatible with any of the parts, so probably the best option is to replace the amp too. I used a Hifonics Eagle which is very small but sounds good. Then Infinity Kappa components because they came with crossovers so I didn't have to deal with the seperate tweeter lines. You could just buy 4 crossovers and keep the delco speakers, connecting the tweeters to the midranges. The subs are now Rockford Fosgate Punch and the amp for those is a US Acoustics USX2100. That's way too big and hard to hide. It's zip-tied to my spare. It's really hard to find any kind of amp that can be hidden anywhere. From my experience, this car is probably the most painful if you just wanted to replace the HU.
OK, I could try and keep this on topic with another pic of my LCD?
