You mentioned a 220 watt alpine amp...do you mean a MRP-T220? If so, that's only 140w RMS @ 4ohm mono, or 2x50w RMS. It's a small amp, the bare minimum for a subwoofer application, however it should be adequate for your Polk 8".
I'm not familiar with the Polk woofer, but it should accommodate a very small enclosure (basically big enough to hold the speaker itself) the amp that i will buy is the Alpine MRP-M450 stated at 220W RMS. i think it will be ok for the 8" 200W PolkMomo. right? Jazz |

BTW, how's the hearse coming along? Any new news? |
Well from what I can tell, those MOMO subs come 4 ohm DVC, meaning that either you will get too much power from the amp (400rms at 2 ohm) or not enough (100? at 8 ohms) So if you're looking at running only one sub, try finding a smaller mono block that will give you 200rms at 2 ohms. I might be wrong about the coil configurations, but I'm assuming that they only come dual 4's. I have an re8 and it is also dual 4.

Providing that it is a 4 ohm single voice coil sub it appears to be a good match. So how much room are you willing to sacrifice for the sub? I would make a decent (big) sized box and tune it low and you will probably be amazed that it's an 8. Do any of your friends have a set up with 8's? A buddy of mine had 2 8's in a big ported box and it sounded great. Best of luck.

Hi, I'm trying to find out what size speakers fit the front doors, and in the dash for a 2000 grand caravan. I know 6x9's are in the back. Any info would greatly be appriciated. Thank's.: stroke:

I know you're new, but read the rules before you start posting....please.....:newbie: |
Sorry Big Red Guy, I wanted to start a new post but couldn't find where to start one. I promise not to do it again. In the meantime could you help me out. I looked in the manual but nothing in there "NEGATIVE". Thanks.
