AMP suggestions - sep'r8 real from hype -

[Techspert 10+ year member]

I was told by an installer shop that McIntosh amps are top of the line and extremely clean; however, they also mentioned that McIntosh overrates their power ratings and will not give you the kick or dynamics of amps such as JL or the new MB Quarts-type amps.

Is there any truth to this?

I'm looking at possibly purchasing a McIntosh MC4000M 6-channel locally that produces 4x100 and 2x300 watts. I'm gonna do MB Quarts components and 1 13"JL W7 ported, OR 2 JL W6's in a sealed enclosure in an '02 Range Rover. I'm hoping the McIntosh will be appropriate and a perfect mate for this setup.

They're suggesting that their in-house JL 450.5 and JL 1000.1 would be a better match.

I'm not worried about the money spent of the McIntosh in comparison to the JL stuff, but I do want the best sound.

Your comments and opinions are appreciated.

Thanx.

power is power, so buy 3 mcintoshes

I would want to stick with the 1 unit since it seems to be powerful enough to drive the entire system.

it is NOT powerful enough to push a 13w7 OR 12W7 OR 10 W7

Not enough???

It has 4x100 for highs and 2x300 for the subs...are you sure?

I would think the 2x300 could be bridged or something to get at least double the power.

Maybe not enough to play at the volume he likes but for an SQ system it would be plenty.

Ohhh jeez, 600 watts (proly more like 800) would be PLENTY, especialy ported.

noooo u didn't consider ohm loads buddy.......

 

[helotaxi 5,000+ posts]

Depending on the enclosure, the amp will not "see" 3 ohms out of that sub, but rather something more. It should be able to be bridged into one of those subs and give it plenty o' power.

i disagree...

usually when u bridge an amp the min ohm load is 4ohms

 

[limitkid7 5,000+ posts]

pls don't spend that kinda money on an amp and have it not be stable....

u need at least 500 watts for the 10

need 750 at least for the 12

and need at least 1k for the 13

invest in something else........ go w/differne tsubs if u have to

The MC4000m is stable down to 2-ohms. I would consider trying another sub type of the w7 requirements were a little too high. The requirements on the w6's should be in my ballpark.

True. And usually a sub (or any speaker for that matter) will not present its nominal impedance in a real world application. It will be something higher and will vary depending on frequency and enclosure.

I agree that there is no reason in the world to spend that much on that amp, stable or not.
