User questions & answers

Question: Do you need the crossovers for the tweeters for installation? Or can another amp be used? If not, where can I purchase them
Answer: The pir sensor can be used as a door sensor (its uses motion to go off). If you can find them. They also sell additional door sensors separately. Yes you can use a camera, but it has to be compatible with the system. (I haven't found one yet).
Question: How do these hold up in a salt water environment? Are they waterproof
Answer: Yes
Question: Do all four speakers come with speaker grills
Answer: Yes. But only by phone call, not by any direct wired connection. The built in cell phone will call up to 6 numbers (if I remember correctly) and give a message you prerecord. So, it will call a monitoring service or the police if you like. It also has a built in battery backup that operates everything except the led screen.
Question: Does anyone know how these compare to the discontinued DB 651's
Answer: Dear Friend Hello, thank you for your inquiry, I am very sorry to give you a late reply. This alarm host is WIFI+SIM+APP. It has no 8 wired defense zones. Thank you!

User questions & answers

Question: Will these speakers fit 2018 Dodge Ram 1500 crew can
Answer: I am not sure. It didn't exactly fit my Delta 10 inch band saw but I made it work
Question: Do all 4 speakers come with the protective plastic cover? Photo shows 2 yes and 2 no
Answer: They are a good replacement when the old plates get chewed up. and I suppose using a fresh one when working with tiny parts could be useful. I have them as backups when the one gets pulled out and cut by the blade. But I cut a lot of odd materials.
Question: Is this price for two sets of 6x9s
Answer: it is a hard plastic, a tad brittle but works well. I did not have my saw guides set well with the first one and it was "eaten" up. However after re-adjusting the guides the second one is working very well. Fits well in the saw.

User questions & answers

Question: Can this pair fit a door on a Nissan, that requires 6.5 sized speakers ? If yes, how so ? Thanks
Answer: You can try to find conversion plates since they are a smaller speaker for the 6.5 inch speaker hole for the Nissan. However, I would recommend that you just go with a pair of 6.5 speakers since they are what would fit without modification, plus the speaker size between the 6.5 to the 5.25 will be better. Better quality, Deeper midbass, etc.
Question: What is the thickness of the speaker
Answer: 2 5/16"
Question: whats the cut out size of mounting hole
Answer: It calls for 4 and 11/16" but I used a 4.5" hole saw and it fit perfect..
Question: What is the shipping weight / dimensions
Answer: Approximately 1 to 1 1/12 lbs, 13"x7"x7".great sound for the size,great marine application
