Conclusion: These speakers sound amazing. I have matching T152 up front and the T1692 in the rear deck in my 95 BMW M3. They put out some tight mid bass, sounds like if I had a small sub in the trunk. I'm powering them with R300X4 amp. Buy them, you won't be disappointed.
Conclusion: Installed these a couple weeks back & they jam! I have a 400w alpine amp pushing them along with my door speakers. I'm surprised how nice they sound, clear highs with good mid bass. I'm pretty sure they'll sound even better with a rockford fosgate amp pushing them.
Conclusion: I was a little bit skeptical about these,, but when I got them and opened up the box !! Wow they were huge , I mean very beefy,, unlike the cheepo crap that some discount chains sell .... Installed them , and wow !!!
