New Subs

[Powerquest1]

I just bought a pair of new 10'' subs for the boat can anybody recommened what size amp would you suggest. They are boss 10'' subs. I already have 6 alpine speakers on a seperate amp for the cockpit & cuddy. Also should I port the boxes or not? I have not decided if I am am going to put them in one box or two seperate boxes.

[rweber81]

A 300 watt 2 channel amp should be fine. I wouldn't port the boxes.

Get an amp that puts out about the same rms watts as the recommended max rms watt powerhandling of the subs.

Power amp like Griff said.

I would port, much louder especially at certain freq. The port does allow more air to potentially get to the voice coil which could be a cause of failure down the road but as with most things marine, life expectancy is reduced anyway.

I hear an aluminum voice coil has less problems, usually found in higher capacity subs.
Also play it a couple times though out the winter to help prevent corrosion.

If you wanted a more specific answer, you need to provide more specifics, model, rating, etc.

"I have a 26' boat, how fast do you think it will go".........

Sloops right, if you want loud bass, porting is the way to go. If you want tight, punchy bass, sealed is the way to go.

Have you thought about a bandpass box? The speakers will be protected from damage that way.

No, but thanks good idea. Thanks everyone!

Over Power The Subs Then Turn The Amp Down So You Can Keep The Power Clean And The Amp Cooler By Not Running It At Its Maxes

They are 10'' Boss subs ava-100, 600 watts power handling, freq response 25-2.5 with 4 ohms

Thanks

My other question is if my other speakers are running off a seperate amp do I only need a 2 channel amp or just a mono amp. I don't think I need a 4 channel amp or crossover but I don't know.

Yours truly, amp dumbass

mono amps normally have some characteristics that are better for running subs, such as built in low pass crossover, subsonic filters & maybe class d circuity. higher end ones also support running at 1 ohm or lower. but in your case a decent mono or even a 2 ch would work well.

what size?

[BDiggity]

what size?

depends on the subs specs; rms/max watts.

I think if you check the specs, they are 300w RMS 600 max. If you are pushing them with a comperable quality amp, use the 300 figure.

or pdx1.1000 if you want some power to spare.

[Griff]

Those will be 600 watts peak. I would bet 200-300 watts rms. An Alpine PDX 1.600 will work just fine and actually will put out about 700 watts rms. Adjust the gain on the amp as needed.

Over Power The Subs Then Turn The Amp Down So You Can Keep The Power Clean And The Amp Cooler By Not Running It At Its Maxes

This is great advice. Many people often think they bought crappy subs, simply because they are underpowered. Only thing to be cautious about when amp shopping is that you want to check an amps efficiency. This is a relative number that reflects how much currenty draw on your batteries is taking place compared to output. I recently had some Rockford Fosgate amps. They are great amps, but they really dont belong in a boat unless you are listening ONLY when its running. They draw soooooo much power.
