View Full Version : Polk Momo 465 Components in 92 Civic
12-06-2001, 06:19 PM
I was wondering if there was any modifications needed to fit the 6.5" midbass driver into the doors. I have the Infinity Reference series 6.5" coaxials in there right now and I cut the factory basket down in order to get those in. Would the midbass driver interfere with the window and also would I need to shave the factory basket down to just the ring? Thanks.

Also, I was planning on running one Momo 12 off of the Nakamichi PA-1002, giving it almost to 400Watts bridged. Would this be enough power?
Yes you will need to shave the back off of the mounting rings. Plus you may have to build a custom spacer ring to accommodate
the depth requirement for these drivers. I would suggest using ABS plastic, or a marine grade of plywood for the building material. You can also pick up about a 1/4 of an inch if you remove the "beauty cup" that is mounted to the back of the driver. If you have any questions, give us a call at 800-377-7655
between the hours of 9 AM to 6 PM Eastern time and we will be glad to help.

Thanks for your help Kim!
I have another question:
I currently have the Alpine 7875 headunit right now which pushes 60Watts x 4 (approx. 30Watts RMS/channel). When I get the Polk Momo components, I won't have an amp for them yet, so would it be okay to power the Momo's off of the headunit? I don't listen to my music too loud, but I'm afraid it might not be able to reach moderate listening levels if I do not have an amplifer to the components. Thanks.

i would not suggest doing that, i don't know what kim will have to say about it though but if you turn up you reciever than you will distort the subs some also it will draw power from everything and you probably won't be able to hear it hardly at all i would suggest getting all of your components hooked up and then buy an amp for them if your reciever doesn't do the job and then going out and buying an amp for the subs and getting them all hooked up

How does running the components off my headunit distort the subs? =P The two subs will probably be powered off either the Nakamichi PA-1002 or the MTX Thunder6500D. I'm just worried that 30Watts RMS might not be enough power for the components.
The problem with "high powered" head units, is that the power rating is a peak power rating, not a continuous power rating. Plus the distortion levels can reach as high as 20 to 30 percent at their peak power levels. This is what causes drivers to fail.
I would suggest waiting to install the components until you have a dedicated power amp to drive them. Look for a power rating of 85 to 150 Watts per channel.
