Conclusion: I highly recommend this brand not only because its alpine, but because it's actually a great product. I only have these running off of the stock amp and they still sound great! I do recommend getting a small amp if you want to get the true power out of them.
Conclusion: I have a 1999 Oldsmobile Intrigue with the stock stereo and speakers. I purchased and installed the following Alpine components: CDE-W235BT Head Unit SPR-50C Front Component Speakers SPR-69 Type-R Rear Speakers KTP-445A Power Pack Metra 70-2001 Wire Harness Metra 95-2001 Double DIN Installation Dash...
Summary: These are a great pairs of Speakers. I installed them in a 2003 Buick Park Avenue. I rewired all the speakers with new wire and hooked it to Rockford Fosgate Punch P4004 50W x 4 Car Amplifier. I put the Crossovers in the trunk and ran 2 sets of wires to each door.
Pros: They mount perfectly in my car and sound great
Summary: I have been very satisfied with the speakers. They are paid with an alpine amp 110 rms. the sound great and never seem like they are working hard. Very satisfied as I got the second pair half off from Crutchfield special
Pros: Fit in car perfectly. Sounds very clean
Cons: Tweeter is very high... Even with crossover set at the 2nd highest setting. Probably need to adjust it all the way down. Crutchfield service was great!
Summary: Maybe it's the Alpine PDX-V9 amp I got to power my system, but something just isn't delivering the punch I had hoped for. While the sound is quality, I was really hoping for a more powerful system.
Conclusion: You will not be disappointed with these speakers. The sound quality is far and beyond what my oem speakers did for me. The only problem I had is I can't roll my windows down anymore because the speaker is so deep. However, this was a bit of poor planning on my part.
