I am looking for an amplifier to power a subwoofer. Most of the amps I look at advertise at 14.4 volts, which gives them a higher power rating.

I was ready to buy an Alpine MRD-301 (300 Watts RMS) only to find out that it would be closer to 250 Watts for my car's system. I I know it's not that different, but it seems like I'd have to fork out over $400 for a decent amp that puts out 300 watts RMS at 12 volts.


What I ask is:
With a WLaurent box (10" Speaker), can someone offer some good amp suggestions?
I'd also like to know what is involved in changing my car's system to provide 14.4 V instead of 12 V. Just for knowledge, because it'd cost more than just getting a better amp I'm sure. I remember reading years back that auto manufacturers would soon adopt this as the standard (I don't know what happened to that).


Thanks for the help,
Barrett.

 

When your cars running im almost certain you are getting over 13 volts...

 

You car running puts out 14.4 volts, 12 volts when not running.

 

Exactly. You already have 14.4volts

 

Wow! I feel like an idiot!

I'm going to leave the original post for informational reasons

So I will buy the amp. I'll just make sure to get a dual voice coil speaker then.

Yep, thanks. The amp is rated at 300 W under of 2 ohm load. Power output is less with 4 ohms.

 

Ah! It's a mono amp! Just wanted to make sure it wasn't one that can do 2-ohms in stereo only.

 

I like the Infinity Reference series amps. I have the 7520a, and it puts out 283WRMS (but at 4-ohms). There is a mono amp in this series, that puts out close to 300 I think. They are rather large, but have good sound.

Thanks for the info. I bought an Infinity amp years ago, when they weren't making many amps. It was a digital amp and it gave me more trouble than I was willing to deal with. Just wrote off the spent money as bad luck. Glad they have a better product now.
