Rated 5 out of 5 by from Hits hard and smooth! Like the title states, it hits hard, and it hits smooth. Moves my entire car in all the right ways. Definitely a smart purchase, and a great deal for a beautiful box and sub. This sub blows my old one out the door, and I couldn't be happier that i picked one up.

What is the best amp from JBL to pair up with this sub? 

Asked by: Cameronc
The S2-1224SS can handle 275 watts of RMS power handling. This means that any sub amp with an impedance of 2 or 4 ohms and a power output of 275 watts will work fine with these speakers.

Is there a different RMS at 2ohm and 4ohm settings?

Asked by: nbeda
The S2-1224SS can handle 275 watts of RMS power handling. This means that any amp with an impedance of 2 or 4 ohms and a power output of 275 watts per channel will work fine with these speakers. That said, the power that the speaker can handle remains the same whether it's switched to 2 or 4 ohms.

Hello, what is the best JBL amplifier for this sub ? I mean an exact product like GX-A3001 or CLUB 5501 or something that will fit better with this sub. Thanks !

Asked by: spusLuci
The GX-A3001 is a better choice than the CLUB 4505. Since this sub can handle 275 RMS in 2 or 4 ohms, the GX's 300 watt RMS at 2 ohms will service better.

Hello. I want to buy this with a GX-A3001 amplifier for my BMW 4 Series. Do you thing it will be a good match the sub and amp with my car?

Asked by: Gabitzooo1
Hi. Yes, this should be a very good match, and work fine in your car. You will want to secure free passage of sound from the trunk into the cabin, if those are separated by sound-proofing materials.
