What Amp(s)

[shag]

I am a novice at this..... So bear with me.

4 polk 6.5's in boat (60 watts rms)

2 Infinity 6000M tower speakers (don't laugh)

1 polk 10' sub

deck is a JBL MR18.5 (4 X 45 watts) 1 set of pre outs

What is the best way to power this system, and be able to control tower speakers separately (fade)

I know this is a hodge podge - but I am on a shoestring budget.... I'm thinking the most important part of the system will be the amp though - so I want to do it right....

Thanks for any help...

Mike

Oh, this is in a restored 91 BF.

Already upgraded to a two battery system and a 100 amp alt.

4 polk 6.5's in boat (60 watts rms): Kicker KXM800.5 or the Arc Audio XDi805

2 Infinity 6000M tower speakers (don't laugh): IIRC, these are a 2 ohm @ the pod terminals. I would suggest a 2 chnl amp with a 2 ohm x 2 RMS between 150-225. Kicker KXM400.2 or rewire the pods to 8 ohm and run them bridged on an Arc XDi804

1 polk 10' sub: Chnl 5 of the Kicker KXM800.5 that would drive the 4 in-boats or Arc XDi805

deck is a JBL MR18.5 (4 X 45 watts) 1 set of pre outs: Kicker ZXM-RLC will give you tower and in-boats zone control with only a single output needed. Add in the Kicker Sub control and you know have 3 true zone volume control. The ZXM is also a 9V per chnl line driver.

Thanks for the reply!
Is there any way to do this with 1 amp? is there a 6 channel? which If I'm thinking right, I would need the 4 channel part for the cabin speakers, 1 channel for Sub, and maybe 1 for tower speakers? I am on a budget too, soooo..... I know, you get what you pay for. Forgive my non experienced rambling....

Shag,

There are some 6 chnl amps that could drive the 4 in-boats, a sub and a pair of tower speakers, but odd are, the sub and or tower speakers will be way shy on power. JL has a new 8 chnl, but like the 6 chnls, its probably going to be more then 2 amps.

New JL should be around $700

I'd go with a PPI 900.5 for in boats and sub and a PPI 600.2 for the tower. About $350 for both amps and will provide decent power for your setup. The 600.2 will be a little strong for your tower speakers, but I'd rather have a little too much power than not enough.

If you want to control the tower seperately I'd just put a "bass knob" inline on the 600.2 to give you volume control for the tower. $30 and your set there.

[tommy1005]

Forgot about one set of preouts. Go with the kicker setup to get 3 zone control and the 9V line driver

[nyryan2001]

^^^ I think you are confused. 600.2 does 190w x 2 @ 4. That's underpowered, not overpowered.

the 900.4 does 450w x 2 @4, if that's what you meant...but most folks know it doesn't do that, 375w max at 14.4v. But yep, not a bad choice for towers. I have one.

the PPIs are a great value for the money... But their internal power supplies are weak, and they are about the most inefficient Class D's as they get waaaay hot.... That heat is Wasted battery power.

[tommy1005]

the 600.2 does 190x2@4, the Infinity speakers are 2-ohm at the terminal though, so the 300x2@2 rating is where I was saying it would be a little overpowered for the tower speakers. 4-ohms per speaker, 2 speakers in the pod makes it a 2-ohm pod.

I've run just about every brand of amp over the years and if someone is on a budget, there's not much on the market that will be better power for the money than the PPI Phantom series.

im not 100% pos, but i dont think the bass level works with 600.2 in any other mode but low-pass. So it wont work for tower speakers in hi-pass. If by bass knob, do you mean a line level POT? This allows one to lower the towers volume, but its the in-boats that blast the passengers when the volume is up to give music to the boarder. Id put the line level POT in line on the in-boat amp $.02.

300W per pod is 150W per driver. Thats a bit strong for those infinities, but manageable with proper tuning and some discipline on the volume knob.

[shag]

So I found this amp that I forgot I had. This is not what drove the infinty towers before, but I think that it will suffice. Now, how should I hook them up? I'm sorry, the OHM thing is confusing to me. :/

Being a 2 chnl amp, you will wire each pod's + and - to a chnl. The amp will need a single RCA pair. The one down side to that amp is that is looks to NOT have a cross-over filter to allow for hi-pass operation.

So do you think I'd be better using this amp for just the in boat speakers? And get another for the tower and sub?

[MLA]

Well, the 6.5" in-boat speakers, like the 6.5" infinity tower speakers, will be better off running hi-pass as opposed to full-pass. So unless there are more amp controls on the other side that I cannot see, id say it was doing a good job as a dust collector in the garage.

What make and model is it?
