Thomas88DL

So I have a 1988 Subaru DL Wagon I got a few months back for $1400 with 60k miles runs great and It’s been my daily since February. But I’m wanting to upgrade the audio. I purchased the Metra 70-8900 harness adaptor, working on making a bracket to fit a new head unit but I realized with the set up I have I’m concerned that the alt and battery may need upgraded to compensate for the power I’m going to need for the amp. Has anyone done anything like this on their pre -90 Subie? I’m looking to install my 15s from my previous daily and the 1400w amp I have.

So, I got this Subaru DL Wagon back in February. It’s only got 60k miles on it it’s honestly in great condition but I’ve now broke both CV Axles, driver side was simple replaced in axle good to go but the passenger side broke and tore up my hub. (Think the previous “owner” The Subie dealer that I got it from) put the wrong ones in and just pressed till they fit. Any ways I have been looking for a new hub does anyone know if the justy front hub will be a direct replacement for the stock one on my 1988 DL? Thanks for any advice or any where I can get the right part I’ve called Subaru and the parts guy laughed when I said what I had haha
