Papaslim.....
Nice edit on your post... However the specs on the SSA site are WRONG. I have installed this amp in a buddies jeep with a pair of Sundown SA-12s, box tuned to 27hz, and that amp had no problem playing well below the boxes tuning like a champ with authority.
It would be STUPID for any company to make a monoblock amp for subwoofers, and than not have it play over half the frequencies that the sub stage of an audio system to play. I cant believe a person would be so blatant to think that, and continuously argue the specs that are listed on SSA are correct against people that have hands on experience with these amplifiers even after the owner of the company posted them in this thread, where as SSA is just a retailer of the product and many other products and made a typo.
Now if you want to continue your Disbelief of the specs listed in this thread posted by the owner of the company and continuously argue about it, you will be having a short vacation from the forums...
PS: if you would even goto Skars website, and look at this amplifiers specs, you will notice they are the same specs listed in this thread, and show you that SSA has listed the specs wrong and made a typo.
