Alright, so my ?88 244 is having an electrical issue I believe. About a month ago, the alt belts started squealing as well as all the lights in the car occasionally dimming. This problem persisted for about 2 weeks till I took it to the local euro mechanic in my area & he let me know that my alternator was overcharging, & he recommended getting a new alt & installing a new battery as well since all that overcharging fried up my battery. Fast forward to now, I?ve installed a brand new alt, as well as a new battery & it?s been riding completely solid for about a week. However, the belts started shrieking again just now & the powers giving signs of going dim again. Now I have a very good suspect in mind for what?s causing this. Before all of this ever started occurring, I had just installed 2 new front speakers in the car. (https://www.bestbuy.com/site/pionee...l-speakers-pair-black/6065206.p?skuId=6065206). I never really did any research on speakers for my Volvo before purchasing them & I believe that they may be sucking too much juice out of my alternator & that?s causing it to overcharge? What do you guys think? I even just uninstalled them off the wires & the car actually does seem to be doing better. I just want to be sure that it?s the speakers. Thank you.
