I was looking for something that puts out a little more volume, with clarity, than my stock 2000 S4 system, and a guy at my local audio shop said that memphis speakers would be awesome. The passengers door speaker is blown, so I have to do something. I heard these speakers at the shop and I thought they would do the job, but the price (for 4 of them) is $225 installed. That sounds really low for good quality stuff. He also said that Memphis is really big on the east coast, but I've still never heard of them. Does anybody have any opinions? What else do you guys have in your systems? I already have a 10 inch sub, and MTX amp, and i would prefer not to replace the deck. Any help would be appreciated. Thanks!!
