I'm about to have a Kicker Solo Baric L7 15 installed but I need to know if I should get a 2 ohm or 4 ohm. I don't know a great deal about audio stuff, the amp I am going to use is the Kicker KX800.2. If anybody knows about this amp and knows whether or not I should get a 2 or 4 ohm speaker let me know. I'd greatly appreciate it.
THanks

The minimum impedance for that amp when bridged is 4ohms.

 

wow 4 ohms , try going for an amp with a minimum impedence of 2 ohms or less

either way oit will sound great but u can get more power form less impedence

just dont try making that amp 2ohms or it wont last long, alot of amp will have a circuit protection if teh impedence is dropped below what it can handle

 

Damn, that sounds like jibberish to me. I've spoke with about 6 different shops, and I get a different answer from everybody. I ended up ordering a dual 2 ohm voice coil L7 just because I went with the majority. So you're saying if you run that amp at 2 ohms i'm liable to burn it up faster than if it was at 4? Sorry guys i'm extremely ignorant when it comes to this ****.
Thanks,

If you will be bridging the amp then you must connect a 4ohm load to it. If you use the amp in 2 channel mode than you can run it into a pair of 2ohm speakers. Since this is for a subwoofer I assume you will be bridging the amp? In that case take your sub with dual 2ohm voice coils and run them in series for a final 4ohm load.

Very few 2 channel amps on the market today can handle a 2ohm load when they are bridged. A better amp option would be a mono Class-D subwoofer amp that can run at 2ohms without any problem. In that case you would need a sub with dual 4ohm voice coils ran in parallel for a final 2ohm load.

 

It's not really the case that you won't be maximizing an amplifier if it's not run at 2 ohms. You need an amp that matches the subs you're using. Think of it as matching a cam to your motor application.

For example, my home amp is optimized for 8 ohm impedences. It will take a lower ohm load, but that means more heat and stress on the components inside. Sorta like using a huge cam on an otherwise stock motor. Won't run properly.

Your sub has a recommended power rating of 1000w RMS. Since you've decided to buy the dual 2 ohm sub, you need to find any amp that will produce that power at either 1 ohm or 4 ohms.

Good choices would include the MTX 7801 (If you can find a retailer with them yet) that delivers 1200w RMS At 1 ohm, a JL 1000/1 that delivers 1000w RMS at any impedence between 1.5 and 4 ohms, a Soundstream 1600.2 which delivers 1600w RMS at 4 ohms bridged and the list goes on and on.

Basically, find an amp that has a reputation for reliability and power output that produces the power you need at your final impedence in the price range you can work with.
