woofer wiring bought wrong amp?

Just got a killer deal on a brand new still sealed alpine mrx-m110. 150$ I had two 12" type r's originally powered by a 900rms kenwood, but the kenwood wore out eventually and kept blowing fuses. I think I clipped it. These are the first gen type R 4 ohlm dvc. Anyways I always thought that the lower the ohlms the better. I may have been wrong though. The m110 make 1100 at 2 ohlms and only 800 at 1 ohlms and only 650 at 4 ohlms. This is confusing to me because I was planning on wiring at 1 ohlms to get maximum power. What is the best method to wire up my system now and did I make a mistake in my purchase?

Funny how often I read on car audio forums how the lower the ohmage, the better the sound. If they mean power or volume then I agree. But if "better sound" means better quality as in clarity and faithful reproduction (which IMO it usually means), then LOL! Not that I'm an audio expert, but the all the authoritative texts and people I know have said the same. None have said lower ohmage/impedance is better quality. And that is consistent with what I'd expect from the theory etc that I know. I often wondered if it was a chicken & egg misunderstanding, ie that people assumed lower impedance speakers were made because of better quality (as opposed to extracting more power from a low voltage amplifier; like why would anyone want to increase current consumption when increasing the voltage overcomes the higher current issues?) or if it was more marketing bullsh (like audio stiffening caps etc).    That doesn't solve your issue - I'll leave that to others. I'm merely supporting everyone's right to my opinion.

is this a purley mono amplifier or is it a 2 channel amp? some 2 channel amps will give you more power when bridged across the channels but in return the ohm load must be raised. for example it might give you 400/channel at 1 ohm each channel which would equal 800 watts but if you bridge the channels you must raise the total ohm load to 2 ohms and the amp might give you more power because of how it is designed to be most efficient at 2 ohms.

this is a mono channel amp. there is only one negative and one positive terminal. Sucks huh? I guess I'll just wire it a one ohlm and deal. I'm sure it will run fine. I also have a scope to check for clipping now so that's cool.

I can not find any info on an MRP-110.   Are you sure it is not an MRP-1000? If so, that amp is not 1 ohm stable. 600 into 4, 1000 into 2 with a peak output of 2000 watts X 1 I think that is where you are getting the 1 ohm info. It is NOT 1 ohm stable.

it's the mrx m110. not mrp. It says it's peak power output is a 2 ohms (1100wattsx1) The rating for one ohm is 800 watts x1. I have two 12" woofers each with 2x4ohm voice coils. I believe the best way to set this up would be to wire it to one ohm, but then I won't be getting the amp's peak power and the amp would be working harder than it needed to in a sense. Is there a better way to set this up?

You could use both woofers to get 1 Ohm, or one woofer for 2 Ohms. It is a mono amp, and it's 1100W into 2 Ohms or 800W into 1 Ohm. (Being Alpine, that's Watts RMS - naturally!!) They are obviously limiting their 1 Ohm output (current limiting?). But using only one speaker means a limit of of 500W versus 1000W using two, hence power-wise, using both as 1 Ohm may be better. (Unless they mean 500W per coil, but that IMO would be clearly stated.) And using your existing 2 woofers means no set-up change other than their wiring.

The MRX M110 is a great little amp, but it is only 2-ohm stable. Use the wiring wizard in the left column and wire for net 4-ohms would be my suggestion.Support the12volt.com
