I have a Forester premium that has base sound system. My previous Forester I had an aftermarket alpine headunit and hefts audio speakers put in and sounded great. Also had an infinity bass link sub. I was looking to upgrade the speakers again to hertz audio and put the sub back in. I saw the Rockford Fosgate upgrade and it looks like much less expensive than what I was looking at. Has anyone heard these speakers or knows the model of them. Wanted to read reviews online. I see also comes with an amp which is nice. Maybe I can find them in a car audio store near me to listen to first as well. So would have base headunit plus my sub woofer and new speakers. Just can’t afford the 700 or more to get the hertz now.
