Perfect amp?? alot of ppl please answer!!!?

Question

is this the perfect amp for two 12" alpine type e's?

http://www.sonicelectronix.com/item_6471_Alpine+MRP-M650.html

Amplifier specs

400 watts RMS x 1 at 4 ohms (600 watts RMS x 1 at 2 ohms)

Subwoofer specs:

Power Handling:

Peak: 750 watts

RMS: 250 watts

Impedance: Single 4 ohms

so that should put 200 watt rms to each sub. is that enough? or should I get a different amp

Answer 1

here are your wiring options http://www.the12volt.com/caraudio/woofer... so you can impedances of 2 or 8ohms

so that amp will give you 300watts RMS to each sub because you will be at a 2ohm load at the amp (not 4ohms)

its a good match because its better than under powering your subs

If you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub.

be sure to set your gain correctly- thats the main cause for sub damage- its not for power/volume

Setting the "gain" or input sensitivity control is an important adjustment common to all amplifier installations. Proper gain setting helps reduce noise and distortion and allows for the widest possible dynamic range.

Answer 2

Yes that amp will work fine for your subs, 300W each is not going to fry them. Music is dynamic, It's always changing, You subs are not going to be getting 300W all the time. The power goes up and down with the music, 300W is well within range of the subs. You can also always adjust the gain so that the amp does not even Put out the full 600W. I don't have the formula memorized, but JL audio has a section on adjusting gain. They only cover JL amps, but the general idea is the same. The values will change depending on the amp.

What you going to do basically is play a 0db tone  and using a multimeter adjust your amp to the correct gain setting. This will vary with the amp, it's fairly simple math.

As for the other post about it being a single channel or mono amp. You don't need two channels to run two subs, you'll just be wiring your subs in parallel to get a 2ohm load. Which is a fancy way of saying, hook the positive from one sub to the positive of the other sub, do the same with the negative then out to the amp.

Answer 3

i have the same exact alpines. i have a Performance Tecknique 1600 watt amp. how much is that amp? ya that would be good but alpines sound super clean. just not as loud as more expensive kickers for example. they might sound really nasty at first cuz u didnt tune the amp lol that happened to me. make sure you explore all the possible settings on the amp and on your deck. should push fine. get a ported box for those alpines. sound a little deeper on long bass notes. im currenty selling my amp. 125 bucks if your interested then email me it pushes really good. windows shake and all.

Answer 4

No dude, that is a monochannel amp, it will only fire 400 watts RMS into 1 subwoofer, you cant hook up 2 subs to that amp, sorry bro , if you have 2 subwoofers, find a 2-channel amp, mono amp is for only 1 sub.

i have the same subs as you, alpine type e, try to find an amp that will put out 250 RMS X 2. that will be perfect, dont look at peak power, only RMS, keep the RMS on amp and sub close to each other when buying your amp.
