Everyone here is going to say "get it through an authorized dealer" I went and the cheapest I found was $550 canadian. So I ended up buying one off ebay from demension audio I think and im happy with it. Saved me alot of money as I only paid $340. So I could spend more money on a set of components from my local dealer. Spend whats within your means, just if the product fails you just cant whine about warranty
I'm not worried about warranty. I have been installing subs since mid 80's and I have never had one fail on me not have I ever blown one. JL Audio makes awesome audio equipment. Therefore, I am concerned with getting the best price available!
