Default Blind mounting speaker crossovers?

Anyone have experience with blind-mounting crossovers for stereo speakers? I bought some Polk-Momo MMC650 6 1/2" 2-ways and didn't realize until they were delivered that they have external crossovers. I have no access to the backside of where the speakers will mount in the boat other than the speaker holes that are cut in the cockpit. The crossovers are fairly large (5" x 2.5") and do have some weight to them. I can only think of two ways to mount them - zip tie them to the speaker basket where they would be hanging loose and flopping around or try to velcro them to the backside of the gunnel through the hole cut for the speaker. Neither of these seem to me to be secure or optimal mounting techniques. Should I just return the speakers and get ones with built-in corssovers? Thanks.

If you are using an amp you can mount them by the amp and run the speaker wire from there. Other than that you would have to mount the securley some where inside the speaker hole.

I just mounted those exact same speakers in my boat, last week. I ran crossover forward and mounted it next to the amp just like by u boy said.

Like was said, the crossover can be nmounted anywhere after the amp. You will just have to run more speaker wire.

Thanks for the replies. The boat is an open bow with the stereo mounted in the enclosed head compartment. There are 4 existing speakers - 2 in the bow and 2 in the cockpit. You cannot follow how the existing speaker wires are ran to some of the speakers. I think the wires were ran before they mounted the deck to the hull. So, running additional speaker wire from the amp (which I have to mount vertically in the head on the wall the stereo is mounted to) is just not feasible. I have to use the existing speaker wires. I think I need to just return these speakers and go with ones with built-in crossovers. Thanks.

The head is located to port. On that side, I think I could. The starboard speaker wires appear to cross under the floor. Not sure I could be successful pulling those through.

Pulling wires is fairly simple if you get a carpet snake.

Another option is to mount the crossover to a block of wood, connect all the wires and then use some 2 minute expoxy or 5200 and glue it. You could glue it right to side of the hull.

I was thinking about that last night. I would just need to make sure I could unscrew the crossover from the wood if it were to ever go bad.

Carpet snake?! Never heard of that.

If you open the crossover it has two mounting screw locations in it. Just remove the cover and you can place two small stainless screws holding it against the wood.
