3 out of 5 eggsHit and Miss

Pros: The speakers knock well for some 6.5 woofers. Slap a passive crossover on them and they work slightly better. Nice bass. Not enough to shake pictures off the wall, but enough to shake your pant leg...slightly.

Cons: I bought 2 sets of these bad boys (totaling in 4 speakers). Well, 2 of them have crackled out while the two back ones are still knocking hard. i haven't returned them back to VMInnovations cause it has been 6 months out from purchase date.

Other Thoughts: I'd would buy anyways because customer service is the best and will fix any problem. Better than my dag gum bank.

5 out of 5 eggsSimply Great!!!

Pros: First of all, the company that sold these speakers is great. FedEx said delivered but my door step was empty. Not sure what happened but I never got my speakers, called the company, they contacted FedEx, nothing from FedEx, the company resent my speakers without hesitation. Customer services from these guys is A1. I would be more than happy to buy from them again. Oh yeah, the speakers are good for the price. They are not knocking pictures off the wall but they do rumble very well.

Cons: I think my next door neighbor stole my speakers. LAME-O. Or FedEx dont know how to deliver.

5 out of 5 eggs

Pros: price

Cons: none as far as I can tell

Other Thoughts: I bought these for my '98 land rover discovery who's stock subs had blown out. These fit right in the assembly but the truck door need a little modifying. The speakers themselves are absolutely wonderful and I don't have to listen to the screeching of broken sub woofers anymore.
