the jl audio 10w6v2's continuous power rating is 400 rms.
does that mean i have to buy a amp that is also 400 rms or should i buy one that is 500?

someone was tallng me about getting a 500/1 amp and since it puts out only 70% efficency it's a good amp to go with (talking about the jl audio 500/1 amp)

 

The efficiency is dependant on several things including power supply to the amp and guage of speaker wire. 400 watts RMS should be perfectly fine. I am going with 4ga power and ground/14ga to the 6.5 Momos/12ga to the sub.

JL has a cool chart on their website that shows both extremes and the sweet spot. Try this:

500 puts it in the danger zone.

 

so a jl 500/1 amp and a jl 10w6v2 would not be the best?

 

I think I looked at the wrong sub on the chart. Looks like that set-up would put you in the yellow-orange area which is OK.

That sound like a nice match.

 

ok new question

which amp should i use to power up two mb quart pce216
and also to power up two mbquart pce213

(4 total single speakers (two sets))

 

The way I have always done it, and this is just me of course, if I had a sub that I wanted to run 400 rms, I would get an amp thats 800 rms, and run it half a$$. Running an amp at full power WILL cause it to shut off in the summer (immense heat) and kill the lifespan of the amp.

 

What, do you mount your amps in your engine compartment?

That is a very interesting philosophy. Do you think going say 600wrms powering a 400 watt sub nets the same results?

I will be curious to see if that happens to my Soundstream next summer. Surely there are amps out there that can keep cool enough to not go into safe mode.

 

Yes. You always want more power than you actually need.

 

so to power up these speakers
which amp should i use to power up two mb quart pce216
and also to power up two mbquart pce213

i would need 200/4?

 

bump for my question
