Ok, guys I need some info. What do you guys think about the kicker mx700.5 amp. I was hoping to use just that one amp to power my six in boat speakers and my two tower speakers (since they are regular speakers not the high powered HLCDs) and the sub. I was thinking about buying the Polk db651 speakers for the in boat and tower. The speakers are new in the boat but they are Pyle and I want to switch them. I will at some point get tower specific speakers but right now too many things to buy like slip, lift, amps...etc. I found the kicker amp online for $349.00 is this a good price. I found the Polk speakers from one of the other posts at earmark? I think for $149.00 for 3 pair then another place for $52.oo for a pair. I like the idea of one amp. I have no idea about a sub. Thanks for your help.

The ZX700.5 is a good amp, but your asking too much of to power eight speakers plus a sub. Yea it can power six cabin Polks, mine does. But adding the tower speakers is just more than it should handle and you'll probably have trouble. Your better off adding another 2 channel amp for the towers.

Oh yea, i've seen better pricing than that for the amp.

So it will handle the six boat speakers and the sub. Then I will need another amp for the tower speakers? Can anyone recommend a budget friendly setup? Amp, tower speakers, cabin speakers and sub that is what I need. Tell me what I should plan on spending. I don't think I am going to put in the HLCDs in the tower this year.

You can always run the bow speakers off the h/u and just run the kicker to the rest right?

I unplugged my bow speakers, I have a triangle sac in the bow so no one sits up there anyways.

Razz I dissagree, (wow I've kinda been a pain in the ass here lately!):D
I used to run a 700.5 with the 8 speakers and a sub with no issued at all.
So you run the cockpit speakers to the rear channels that will put the amp at a 2ohm load and the bow speakers wired with the towers which will put the front channel at a 2 ohm load. Thats what that amp was designed to do. Provided you don't mind having all the speakers the same volume because if you want to fade the towers up/down you'll be fading the bow speakers as well.
That amp is a great dependable amp and you will be very happy with it for a long time. The only issue I see is when you decide to go with HLCD's and want to kick it up a little you'll need a seperate amp to do that. however leave the front speakers hooked up to the amp. It will run at a 4ohm load and be just fine there too.
I agree w/ Razz as far as price http://www.sonicelectronix.com/item_11535_Kicker+08ZX700.5.html
Yea... way high and these guys have free shipping.
Hope that helps.

Yeah i know it can be done, i just don't like running 2ohms in a boat with amps in an enclosed space with the heat we have around here in the summer. I tend to forget it's not like that for everyone. :o

Very good point. I think the kickers have fans on them no?
I used to run mine hard in 110 degree heat with the compartment closed.

03-01-2010, 03:47 AM
No the Kicker 700.5 doesn't have fans.

I would look at getting a second amp for the towers. I know your not wanting to go that route but its the best route.

If you realy want to keep it on 1 amp for now then your best bet would be to runt he towers with the front bow speakers and then the 4 cabins.

This will drop all channels to 2 ohms and then run your sub on channel 5.

I ran this amp all summer last year and it performed well. Only 1 time did it shut off on my and it was 110 out and i was cranking the tune for hours. I shut it off for 5 minutes and then it was back on never had it shut off on me again. Not sure if it was really the amp or a connection but i know it was very hot the touch when i checked it.

For that reason im installing cooling fans for my 3 new amps

What polk speakers do you guys run? I think there is a MM650 and a DB651 the MM650 are like $199 a pair and the DB651 you can get for $150 for 3 pair. The Stereo store here said the DB651 is a car speaker not a marine speaker. Is it ok to run the DB651 or not? I think I am going to run my bow speakers off the head unit and the rest off the Kicker 700.5.

03-01-2010, 10:47 PM
Most are running the Polk BD651,s

These are Marine grade speakers.

Cool I ordered the Kicker 700.5 today for $279.00. Great deal!! I am going to order 8 of the DB651 Polks. I will run the bow speakers off the head unit and the rest off the amp. I have to get a sub but have not gotten that far yet. Do you guys see any problem with this set up for a season. I will go big next year. Thanks

Nope, I think you'll be pleased.

03-02-2010, 10:40 AM
Nope looks great your going the same route i did last year also. I went with a budgeted system so i could enjoy it more.

The bright side of your system is as the summer goes threw you will realy see what you do and dont like in your boat, and you will know what you realy want to change for next year.

I have a ZX450.2 for sale in the classifieds, it can be used to run those 2 towers and 2 bow speakers for you as well, if you want to run a duel amp set up.

Let me know if your interested or not. Nothing wrong with the way your running it now just letting you know about the extra amp idea
