Great product

Be sure to break it in properly. Very loud. Shakes the s*** out of my f150. Need a new rear view. Might need to purchase some dynamat

RMS rating is overratted

I had this sub hooked up for 2 days and was playing it at about 1/2-3/4 volume and it blew up. Everything was wired correctly. From what I see from other reviews this seems to be a common problem. I replaced it with a Rockford Fosgate p3d12 shallow and am so far very pleased.

Rated too high on RMS

This sub is rated way to high on RMS wattage. I had it wired to 2 ohm and it blew up within the first two weeks pushing it at a mere 400-500 rms. Very disappointing. I have owned a ton of kicker products and this was my first poor experience. On a side note, Sonic Electronics would NOT warranty a blown subwoofer. I fought with a guy on an email rant for three days and eventually had to get my warranty through Kicker directly. I will say this. As far as the subwoofers sound when it worked, it sounded great. I had it in a ported box at recommended specs for the speaker and it literally sounded like a 1,000 watt sub in a large box. It just simply did not last. I have received my replacement sub and hopefully it will last.

Must know what you are doing

These subs are available in dual 1-ohm and 2-ohm models. If you are running TWO of these.....the dual 1-ohm subs can be used with a classic 2-channel bridgeable OR a 1-ohm stable mono block. If you get the dual 2-ohm subs, they can ONLY be used with a monoblock that is at minium at least 2-ohm stable. If you don't know the difference between series and parallel wiring, you should not be wiring up subs until you do. Most sub failures are caused by incorrect wiring and/or SETTINGS. Anybody can connect wires to subs and get sound. Whether or not they last has EVERYTHING to do with experience on settings. If you are using LOUDNESS or turning your BASS up on the deck that makes you an amateur. You can achieve more by using the amp settings and your subs will last longer too. The RMS rating on these is most likely over-rated. I would guess (by weight and experience) that they could handle a clean 500-600w RMS each when wired and setup properly.

Be Careful

My amp was only stable to 2 ohm and I got this sub from Kicker even though I asked for a 2ohm, they gave me a 1 ohm. It blew as soon as we hooked it up. Kicker is awesome stuff though and always take care of their customers. Hoping for the best on this deal.
