600 rms 2 ohm sub ... what rms for two subs?

[kenstewart 10+ year member]

Have two DVC 8" Image Dynamics subs (300 rms @ 2ohms each). Looking at getting the MTX MXA6001 amp: http://www.mtxaudio.com/caraudio/products/amplifiers/mxa6001.cfm

When you put two 300 rms 20hm subs to a 600 rms 2 ohm mono amp, does this mean the 600 watts are split at 300 to each sub?

check out the wiring sticky for the final impedence load of your 2 subs. then match that to the amp.

Don't have them yet, due to arrive this coming Wednesday. Went on the Image Dynamics site though and all it says is 50-300 rms. Others have said as long as my final impedance matches (2 ohms) then the subs will push what the amp produces ... 300 watts is what I'm after or a suitable substitute (is 200 rms good enough???).

are the subs dual 2 or 4?

Dual 2 ohm

Wire the subwoofers like this:

And they will each recieve 300w.

Thanks squeak. For clarification since I'm a novice, that diagram means to wire the voice coils in series right ... then wire the subs in parallel to the amp to get the right ohm/power????

Yup. Each individual sub's coils are wired in series (for two 4ohm loads), then the subs are wired in parallel for a final 2ohm load.

Awesome!!! Thanks a ton //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Did you have any opinion on whether or not the 200 rms amp (being MTX usually underrates) will be enough? I'm looking at an alternative MTX amp which will save me around $60-70.

Where are you getting 200 watts from, the only amp I see mentioned is the mtx. The mtx will give your subs 300 each.

The alternative amp I mentioned which is the MTX MXA4001 ... if using two subs won't it split the 400 rms to 200 each sub? Just like what was discussed earlier with the MXA6001.

ah, might notice a little difference...not huge, not much money though either. J/c what are you paying for each amp?

Around $200 for the 6001 and $140 for the 4001
