When I bought the boat, I got the package with the tower Rev 10s and 4 speakers cabin speakers. I now want to install some bow speakers. Are there speakers wires ran for both sides of the bow? I dug around and found some available for port side, but couldn't find on the starboard. I did also notice there are 2 opening on the back of the head unit...do they need to be plugged in there?
Thanks in advance

You cannot effectively power 6 speakers with the head unit's internal amplifier. You would need at least 2 external amplifier chnls. If the boat does not have an external amplifier for the existing 4 cabin speakers, I would suggest a 4 or 6 channel amp and relocate all the speakers to the new amp.
Kicker KXMA500.4 is a solid amp.
Anyone know if speaker wires are already in place in the bow?
My 2015 had speaker wires pre-ran. However, the white clips behind the radio and by the amp rack was not connected. By the correct size hole saw and it is a simple install.

I have a 4ch amp running 6 speakers (cabin left 2 are in parallel and cabin right 2 in parallel) amp is 2 ohm stable gain is adjusted to only 50-60%. Other 2 channels are the bow speakers and the gain is at 80% to equal the same volume.
Towers are ran off another amp and set to zone 2.
Sub is the kicker 200x2 bridged at 2ohm to a 12" sub in sealed box under helm.
System hits hard and is plenty loud. No distortion at full volume and not over powering anything.
Being on a budget, get a 5 or 6 channel amp...run cabins and sub off of that and bow to the deck.

No need to have any speakers remain on head unit with this, or any, 4 chnl amp. All the speakers will get 65W rms or more. Thats thats 3X what a typically head unit will supply.i would run the 4 main off an amp and just run the bow off the head unit if you are on a budget.
Appreciate the information...time to buy an amp![]()
