View Full Version : AMP for Prostar 190
05-11-2012, 01:20 PM
I have nice Clarion Head unit and just four speakers....two in the front and two in the back...
I want to install an amp to get a little more out of the speakers (which I know will handle). Any suggestions on an good econimical amp? I don't know much about them...channels, etc? Just want a little louder when riding. No can speakers, no tower...

You can run either a 2 or 4 channel amp, depending on your preference. With a 2 channel you'd have to bridge two speakers together onto one channel to run all 4 speakers, which isn't a big deal, you just lose fade or balance. A 4 channel would keep your current configuration, the speakers would just all have more power.
How much power can the speakers handle? That should determine what amp you're going to buy.

sounds like i might need to go ahead with a 4 channel or even a five if i ever want to put a sub-woofer in bow?

I would go ahead and get a 5 channel in case you ride in a boat with a sub and think, man, I want one! Makes a huge difference - an amp will definately help your 4 speakers. What kind are they? JL's are top of the line but expensive - I have a Memphis Audio 5 channel, but not cheap. I think Malibu uses Kicker now, they are moderate -and I think they are generally considered good. If you plan on keeping the boat long term, go ahead and invest in a good amp.

I bought 4 Pioneer TR1640's near the middle of the summer last year...my boat is a 96' Prostar 190 LT1. Speakers are max 160 watts. I don't want to break the bank, just a little more power. When I installed the new head unit and speakers I used all new larger speaker wire anticiapting an amp later.

Those are 30 watts RMS@4ohms... looks liek 60w RMS@2ohms. Don't try to push 160 watts to those, you'll blow them. RMS is what you need to go by, and honestly, 30 RMS really isn't a whole lot of power... Your head unit is going to push probably ~20w RMS to those speakers (probably a little less), so adding a little more power might not get you the sound you're looking for.

I'm putting the Onyx 4.80 in my PS 190 this weekend. $120 from Amazon. Will let you know how it comes out!

I used the MB Quart 660 (6 channel). Decent power, marine rated, run the 4 speakers and bridged last 2 channels for 12" sub.
About $170 as I recall online.

Here is my MB 4.80 on a cutting board right behind the observer's seat. It's VERY tight working in there so be sure to take some yoga classes before starting work on this kind of project. There is more info about how I secured mine on the fourth page of this thread: http://www.mastercraft.com/teamtalk/showthread.php?t=46548

I run just deck power to the four Infinity Kappa speakers in my Prostar. For added punch I have a 10" sub in a generic enclosure with a 200 watt amp in the bow. Sounds great. The deck pushes plenty of power to the main speakers and the sub really helps fill in the lows. My amp is mounted on the partition between the bow and drivers foot well. I have it so I can quickly take the sub out or move it around in the bow if need be.
I think this is a much better route to take than simply adding power to the four speakers you already have. With the size and the free air they don't have any low frequency response.
Here is a pick of the amp mounted.
