Is this amp powerful enough?...

[lmx107]

I just purchased 2 Aura amps (2300 and 4200), will the 4200 be powerful enough to drive a set of 6.5 component speakers that are rated 150 Watts RMS? Is there anyway to configure either the speakers or amp to make the combination work?

Sure, connect them to the amp - something will work.

Could you be more descriptive with what you are trying to acheive? The 4200 bridged to two channels is about the same as the 2300 per channel power. However, with an active crossover (outboard, the Aura doesn't have tweeter-specific frequencies on its inbuilt crossovers) you can run two of the 4200's channels to the tweeters and two to the 6.5".

Ok... The speakers components come with a set of passive crossovers that'll take care of the midrange and tweeter frequencies. What I was worried about was that the speakers are rated at 150 watts RMS while the amp is rated only at 50 watt RMS/channel.

I was planning on using just 2 channels for the component mids and tweets and reserve the other 2 channels (bridged) for (2) 8 ohm woofers in the rear (wired in parallel for a 4 ohm load).

I have other plans for the 2300 amp and don't want to use it in this configuration.

Given that I have the following 3 options:
50 watts RMS x 4 (4 ohm stereo)
75 watts RMS x 4 (2 ohm stereo)
150 watts RMS x 2 (4 ohm bridged mono)

What would be the optimal configuration?
1. Wire the components in parallel to get a 2 ohm load so I can achieve 75 watts RMS? Since there's already a passive crossover included, I'll be using only 2 channels.

2. Leave the components at 4 ohms for 50 watts.

3. Bridge the 2 channels for 150 watts to the components (but this isn't stereo - right?)

In all the cases above, I want to reserve 2 channels for the woofers?

Did I leave out any other options?
What do you think I should do?

Hey Bruce I would go with your first option. Just use CH1 & CH2 for your components and bridge CH3 & CH4 to your subs. 50 watts is more than enough power to run your components, unless you are just looking for ridiculously loud.

If I bridged them like you said to 2 channels, are those channels still in stereo? I thought bridging the channels make them mono?

Yes - certainly will but can you answer this for me.

"If I bridged them like you said to 2 channels, are those channels still in stereo? I thought bridging the channels make them mono??"

Both of the channels. Bridge the Right and Left channels, so that you have two channels not four but still one left one right.

Where'd you find that one, I like it, very well done. Is that yours?

Yes it is. I used Smartdraw v7.0 and the awesome pics of the amp from partsexpress.

Thanks for your help.

The "knob" is a remote gain control, not technically "bass boost" which would give a particular frequency a boost; like an EQ.

You need to split your RCA input by using a y-cable.

This will give you your four inputs, 2 left and two right. plug the 2 left inputs into channels 1&2 bridge the outputs and repeat for the right side. This gives you stereo.

However I'd bridge to the subs and run the comps. unbridged. The 150watts is thermal power handling. In your door 50 watts could be more than they could handle!

Hav fun,

I hear lots of discussion on what that actually but I just used Aura's terminology which in their specs is "Remote bass level control".

I know what you mean though. Thanks.
