Wetsounds SD6 amp Question

Recommended Posts

Hiifive

Hey everyone!!

Looking to do some upgrades to my stereo this winter. I came across a good deal on a SD6 and now wondering what the next step is.  Currently I have 4 6x9 speakers (60 w RMS each currently,  looking to upgrade 6x9's to 130 Rms each in near future) in the boat and a 10"  (450 w RMS ) enclosed sub. My questions can I use four channels to run the 6x9's and the remaining 2 channels to run the Sub? Sorry if this seems to be a dumb question, but  I am very new to this whole 12v stereo stuff.

Yes, that's the way to do it.  I'll be installing a similar setup in the next few weeks.

Why a 10"? Stepping up to a 12" in that boat should be super easy. There would be little cost difference between a 12" woofer and a 10" of the same series. The enclosure needs of the 12" would be very close to those of the 10". 

You could also drive a pair of two of tower speakers with the SD-6. 2 pair in-boats on 2 chnls, woofer bridged on 2 and remaining 2 for tower speakers.

I hear ya! Unfortunalty the 10" sub is what the boat came with.

Thanks for the suggestion MLA!  Correct me if I'm wrong though, what you suggest could only be done with the current 4-60w rms 6x9's in the cabin already. If I up grade to 4-130w rms 6x9's that would be too much on this channels correct?

If I understand your question, no it would not be.  The speakers do not require a specific power to run (or draw a specific amount)...

The speaker's wattage spec does not determine any load on the amp, but rather the speaker's nominal impedance. So, if your current 60W rms and future 130W rms speaker are both 4 ohm, the amp will never now the difference between them. However, the speaker with the higher power handling, will allow you to make use of more of the amp's available wattage.
