i bought a set for the dash in my 86 caprice,and these are by far one of the best pair of speakers i've ever owned,quality is 100 percent,if you are looking for quality get a pair of these
They are not designed for bass but if you are taking out factory speakers you will wonder how you were even tolerating the factory crap. One word...CLARITY. Very nice product. Installed easily and really woke everything up. I am hearing little nuances in songs that I didn't even know were there. Some of the best 4"x6" coaxial speakers that I have personally heard. Impressive.
Put these in Malibu frt doors. HUGE improvement over the stock GM junk. Of course you must replace the Delco deck also. The bass is limited because of the 4"x6" size, but the midbass is decent with good mids and very good highs.
I put these speakers in my 92' Sonoma. They sound really good, alot better than the stock speakers.They almost dont fit in the dash but i got them in there. These speakers sound so much better than my buddys sony 4x6".
