I put these in my Ford to keep the factory size w/o modification. They are deep, so the doors needed a spacer, but these speakers are WELL worth it! The bass is INCREDIBLE as compared to stock, as well as the highs. The crossover is awesome, you can really hear a difference. These speakers are running AMAZINGLY off of 18 watts each (Ford Mach amp) and would sound amazing off any headunit. Add an amp, and these suckers will blow you away! My friends thought I had a 10" sub with these running off the stock amp.
These Speakers are what I was looking for, Just put them in today. The sound from them is awesome, the highs are perfect and the lows could be better but they are 6x8, am use to old school 6x9 with 20oz mags, don,t find them any more since subs came into play, They are matched with a Kenwood kdc-x592 Head unit and a Clarion apx 4241 4 channel amp, Thanks onlinecarstereo for completing my system..
