So bought, connected correctly and ready. Installation wasn't difficult but there are a lot of wires and for me they were a bit long. So cable management is very important! Anyway, they're not that loud. I would like a 600 watt version. The only reason I didn't do this was because I didn't know where to place the amp. And now that I've got them all plugged in and shut, I don't want to go back. The reason I gave it such a low rating is because they drain the battery. I had to install a toggle switch on a hot wire so I could leave it overnight without pulling the battery out and tossing it on the charger. 1 battery killed in a month. So buyers beware. If you buy them, add a separate switch.
