Hey guys, well I am pretty new to the car audio scene, I have used mostly a single sub setup with a mono amp in the past. I am looking to expand my system and I need some help. I am wondering if the Alpine MRD-M605 Amplifier would power my subs properly. The specs on the amp are Number of Channels 1 - Mono RMS Power (4 ohms) 300 watts x 1 chan. RMS Power (2 ohms) 600 watts x 1 chan. RMS Power (1 ohm) Not Stable Bridged RMS Power Not Bridgeable Peak Power Output 1200 watts approx. Min. Impedance Unbridged 2 ohms Min. Impedance Bridged Not Bridgeable
I am looking to push this sub setup... With 2 Coustic Cf1044 subs 400 Watts RMS/800 Watts Peak Music Power Dual 4 Ohm Voice Coils
Just wondering if I would be alright, any help would be greatly appreciated!
I am not familiar with that amp but from your description you are going to run into a small problem. With the subs being dual 4 ohm your amp will see either a 4 ohm load (series/parallel the coils) or a 1 ohm load (series all 4 coils together). The amp cannot take a 1 ohm load so that is out of the question and if you give it a 4 ohm load you will only get 300 watts to the subs. It almost seems that your best bet would be to see if you can get these subs in a single 4 ohm voice coil configuration that way the amp will see a 2 ohm load. Hope this helps, Tom
you need an amp that will push either 800 at 4ohms or 800 at 1ohm. Try to find an Orion HCCA 250, you might be able to find one for around $250 if you are patient. If your head unit has a built in x-over then you can get the 250r for $250 easily. Great amps by the way
yup it does! I would gen an Orion 250 if I were you. Look for the 250G4 but you will prob have trouble finding one for that price. I just got mine for $275shipped but I had to wait on it. If you are patient you can find one for around your price. If you cant find a G4 get a 250r or a competition,or digital reference they are all nice amps.
I just went to that website and checked it out. If you are planning to purchase the coustic preloaded enclosure ( CF10X2A ) tha Alpine amp will only push 300 watts RMS, the enclosure is setup for 4 ohm from the factory. My best suggestion for an amp would be to do some research on the major brands websites. Try Kicker, JL Audio, Directed Electronics, Precision Power, Orion, Alpine, Rockford, Audiobahn, MTX... Do yorself a favor and stay away from less expensive amps which promise mega watts but actually give out mega distortion and low watts. Look for an amp that will do around 500 to 600 watts at 4 ohm mono, that much power should push that enclosure pretty well. Hope this helps, Tom
Unfortunately with the subs that are peloaded into that enclosure you could reconfigure the voice coils to a 1 ohm load or leave at a 4 ohm load but not get a 2 ohm load and I dont recommend you to reconfigure to a 1 ohm load because you will have to get into a quality 1 ohm stable class D amp and I honestly don't think you will find one at your $250.00 price point. Keep the enclosure at 4 ohm and research a quality class A/B 2 channel amp that will do 500 to 600 watts at 4 ohm bridged. Hope this helps, Tom
