8 speakers on one 4 channel amp

[imq707s]

I have the original Clarion marine tape deck in my boat with the two speakers under the rear bench, and two speakers in front of the front seats. I'm in the process of trying to figure out exactly what I will need to add two bow speakers, and two more speakers in the rear up on the side panels.....for a total of 8 speakers.

I'm going to swap out the old Clarion deck for a new Kenwood marine deck with 6 line-outs...2 for sub, 2 for front speakers, 2 for rear speakers. I know I will need an amp to run 8 speakers off of this deck, and I'm assuming that the best option is a 4 channel amp? Can I run two speakers off of each channel? Or should I run two 2 channel amps?

I was thinking about an amp like this Infinity.....is there something else better for the money? Just looking for something that will sound good, but not drain my batteries too fast.

Any advice would be great! Thanks! http://crowniehq.net/forum/images/smilies/thumb.gif

Assuming you're running two 4 ohm speakers on each channel you will need an amp that is stable at a 2 ohm load or run each pair in series instead of parallel.

You will need a 5 channel amp, that will give you one sub, 2 front speakers and 2 rear. You can do 4 front/rear speakers if you run them like johnr said.
If you want stereo sub you need a 6 channel amp.
Yes you can do it with 2 apms also one for the sub and the other for the front and rear speakers.

I have a inifinity kappa 5 channel amp in my truck hooked to a kenwood and love it, one jl 10 inch sub

4-channel Infinity Amp

10" Infinity Basslink subs for under the engine hatch

4 extra 6" speakers...2 for the bow, 2 for back in the cabin area

The amp is 2 ohm stable...so I should be able to hook 2 speakers up per channel wired in parallel for a total of 8 speakers. For now, I'm going to leave the cheap Clarion marine speakers that are under the bench seat, and in front of the front seats. With those 4, and the addition of 2 in the bow, and 2 more in the back....it should sound great (I hope).

I think I have just about everything I need...except for some wiring. Does it look like I matched all of the components pretty well?

I would avoid the powered subs, I looked into the same one for my truck but after reading alot of negative reviews about it not lasting very long I decided against it. I would imagine its because the amp cant get enough cooling or the sub vibrates the heck out of it.

u could do 4 of u speakers in series which doesn't drop the ohm level of the amp,wire the other 2 straight off the neg.and pos.and sub has own amp just needs rca pre-amp outputs.otherwise use the amp for the subs only n wire the front 4 speakers in series off the head-unit.

[bigbore]

u wanna do series cause it maintains 4-ohm.the other 2 2nd channell straight neg. and pos.(for mids n highs) off other channell of head-unit.Amp 4 the subs,amp might b 2-ohm stable parrallell pos. to pos. (n neg to neg.)on subs,best u can do with that equipment which should still rock.
