These subs are a steal for $50. I see a lot of people online saying bad things about Sony Xplods. But they're entry level subs and Sony doesn't pretend they're more than that. You can't compare these to Rockford Fosgate "Power" series and then say the Sony is junk because the Rockford outperformed it. The Rockfords literally cost 10 times more. Dollar for decibel, these are tips. If your looking for a hard hitting, every day subwoofer, this is exactly what you need. I had a pair of these I bought here from Crutchfield awhile back. I powered them with 600 watts RMS each. And they were far louder than I ever thought possible at this price point. I had them for a few years until I had to sell them. Since then I've had several pairs of subs. All in 500-600 watts range and triple the price of these Sonys. But the Sony's were just as good as all the others. Including Rockford P2s and P1s, Pioneer Champions, Kicker CVR.
If you want a windshield cracker that will hit 150 db, then you better dig deep in your wallet and buy something else. But if you want loud, clear, bass that rattles your mirror off and the kick drum feels like a punch in the chest, these are the way to go. For $50, if you send these enough power, people at stoplights will be mad at you.
Pros: PRICE, PRICE, PRICE
These perform like far more expensive subs.
Cons: The only con is when you tell people you have a Sony explod, they roll their eyes. But if you have the right amp on these, one listen will change their mind quick.
