I have never heard them in action, what quality should I expect if I were to buy two 10's?

ps. In my focus hatchback I had 2 infinity twelves at 1000 watts.. was alittle too much..

There is probably a reason you have never heard them in action. ;)

They are not that great....

They're not terrible if you just want to add a little low-end to a factory system. As long as you don't expect miracles I think you'll be pleased. Personally though, I'd just go with a single 10". If you're going to go as far as to get two of 'em, I'd suggest getting some 'real' subs and an amp to power them.

My opion the bazooka bass tubes SUCK!! I had one a couple of years ago, it was a complete waste of money. I sold at a garage sale for $30

I also heard they suck that is why i went with two 12s.
