Not a bad set of speakers but wanted matching front/rear, and they 651s was too deep in front for my application. Had these installed for just a month or so, but was overall quite happy with them- EXCEPT- they were very bright. Had to have a lot of high end cut to make my ears not bleed.

I got these to use as rear fills in my Tacoma and they sound great. Much impoved over the stock spearkers with just my HU powering them. They sound as good if not better than a set of CDT's I had in another vehicle that i paid twice as much for. Great deal.

I love these speakers. I installed them in my 2000 Toyota Avalon and they sound absolutely great! I already had the JBL system in my car and the speakers were getting old so I upgraded to these and couldn't be happier. Thanks Sonic Electronix for a great price on some great speakers.

Great speakers, I used these speakers on my Audi A6 1998 as replacements and sound quality is amazing so is the bass. These speakers exceeded my expectation. These speakers are fifty times better then the standard factory speakers that came with my Audi.
