Rated 5 out of 5 by from Works in the home as well! Preferred to build my own sub for the house: I have two of these in a sealed enclosure and powered by a 900x2 Carvin amp. These subs are not subtle, they pound and pound. Very happy.

So I want to buy two CS1214 what amp should I get to get the best prefomence. Wile supporting both subs?

Asked by: PaytC
Our best option would be the GTX-500 mono-block sub amplifier. When connecting two CS1214’s to this amplifier, the GTX-500 will see a 2-ohm load and drive the speakers up to 250W each speaker which the CS1214’s is actually what is rated to safely handle. This ensures that you maximize the capacity of your speakers, but not overpowering them.

If I am putting two of these in my car what would be a good amp to go with it?

Asked by: NickyG03
These subwoofers can handle up to 250W of power @ 4-ohms. So ideally, any amplifier that delivers this much power would be great. A recommendation would be the GX-A604, a four-channel amplifier that can drive 170W per bridged channel @ 4-ohms. The GX-A604 can already accommodate both of your CS1214. Or another option would be the GX-A3001, a mono-amp that can drive up to 200W per subwoofer, you need two of these if this is what you prefer.

It will fit my car but where and how is the best place to locate, trunk, floor, other?

Asked by: HEGAWN2
This speaker is sold as a raw driver without an enclosure because most setups will be a customer installation. You can put the sub anywhere you decide works for you. For example, if you want to build an enclosure that will fit on the floor in the back seat, that will be fine. But most people will opt to install it in the trunk.

how many cubic feet should i give each speaker

Asked by: timtom
If you are looking for tight accurate bass, your best bet is a 1 cubic foot sealed enclosure. If you are running 2 speakers in the same box, all you have to do is double the space, making it 2 cubic feet.
