Help with my JBL W12GTI mk2 and RUB1.2500D Amp

Chris New member Username: Chrisinoregon Post Number: 1 Registered: Oct-11	Posted on Monday, October 17, 2011 - 17:17 GMT Hey guys, I'm new to this stuff and would really appreciate all the advice I can get! I have just 1 mk2 12" sub that is 3 ohm or 12 ohm only. I understand that these subs were designed to run in three's to get down to 2 ohms? Or 1.5 ohms, I'm not sure. Anyway, I only have 1 and I'm thinking about buying the Soundstream RUB1.2500D amp to push it. 1) Is this the right amp and can I wire it to get to 1.5 ohms? Or do I have to run it at 3 ohms? Also, what would be the rms at 1.5 and at 3 ohms with this amp? 2) Do you recommend an amp that would better suit this sub...Thanks...Chris

In my opinion you should exchange the sub not the amp if you want to take advantage of all the power of that amp which can deliver 2500W RMS at 1 ohm.

However, I'm not in the market for a new sub cuz the mk2 will work just fine for the car that I'm putting it in. I haven't purchased the RUB1.1200d yet, it is the amp that I am currently looking at buying. Thanks for the education on the ohm of this sub. I just have two more questions 1) PLEASE recommend an amp for me that will work well with this sub, especially if you think the RUB1.1200d will be too much. 2) Can you send me to a link or maybe draw a generic diagrahm on how to wire my DVC sub in parallel to get it to 3 ohms? Thanks again...Chris

From the SS Rubicons below it seems that nothing less than the RUB1.1600D will handle 700W at 3 ohm, it will give 1100 at 2 ohm and therefore less at 3 ohm (not even specified at 4 ohm so who knows). http://www.soundstream.com/AudioProducts/Amplifiers/rubicon.htm There should be plenty other options to choose from.
