Audio Systems: amp recommendations, hifonics brutus, voice coils

Question
QUESTION: I have a DVC 2 ohm alpine typr r 15" sub. Its around 1000 rms watts. I just want to buy the right amp for it and get the wiring correct. The wiring options and ohms confuse me. Can you help with a couple amp recommendations and wiring diagram? Right now the only amp I have in mind is a hifonics brutus on ebay. Thanks

ANSWER: You forgot to mention which Brutus model are you looking at.

As to power, anything over 1000 RMS is probably going to be ok as long as you set it up properly.
You are more likely to blow up the amp and/or speaker by using anything under 1000.


A wealth of wiring info is here:

The enclosure is just as important:

QUESTION: its the hifonics brutus 1600D. its 1600 at 1 ohm. 1100 at 2 ohm and 550 at 4 ohm. the wiring diagram shows i have to wire it at 4 ohm which would only be 550 watts. is that correct? if so i will need a stronger amp at 4 ohm. if i could wire it at 2 ohm id get 1100 watts which would be perfect

Answer
Ok then, CJ.
From what I understand so far:
You have a sub with two, 2-Ohm voice coils.
You can wire those coils together at either 1 Ohm (Parallel) or 4 Oms (Series).

From the Crutchfield page:
"NOTE: Low-impedance systems have been omitted due to the relative rarity of amplifiers capable of driving one-ohm loads (or 2-ohm loads when bridged). Call your Crutchfield Advisor for help in determining how to wire a low-impedance subwoofer system."

So...you CAN wire the two, 2-Ohm voice coils in parallel for a one ohm load.

Wire it just like this one:

Then your two, 2-Ohm coils will end up at 1 Ohm.  ò¿ò

Once you have decided on the tuning point (type and size) of the box, build a seriously strong enclosure for high power applications such as this one.
**Be sure you do not overpower it when setting up the crossover and amp level since it is now a 1600 watt potential you will be working with!

Have fun and best of 'luck'.  Though I have found that the better an audio idea is researched and handcrafted... the better the 'luck' is!


If you have any further questions let me know.
