Re: tower and combo speaker/lights
Hey, I got the combo from ebay over the winter, probably the same you are talking about, 2 polk audio speakers with 3 lights packaged by Aerial. You dont need an amp. I use an amp for my 2 subs under my back seat, but I just wired my speakers on the tower with the normal stereo outputs which I think is 52 watts.
You can hear the music very well from the end of an 80' rope, its also nice in the boat because its loud but not overly "burst your ear drums" loud because the sound is projected towards the wake. I currently run 2 speakers in the bow, 2 under the consoles, 2 on the tower and 2 10" subs and its awesome.
You technically dont need another power source but I added a deep cycle battery, mostly for when I am chilling in a bay swimming, or at the beach, this way, i flip the battery switch and just use the deep cycle. That way i know that if I chill for several hours, I will be able to get back in the boat, flip the starting battery switch and go!
Hope that helps, and for the price (300ish), you cant go wrong with the Aerial combo! It fit awesome on my Monster Tower too!
