I've always pondered the idea of going with a single 5 channel amp to simplify things a bit. It'd be nice to have one amp to power your entire system and to have all of the wiring going to this one amp.

There's quite a few threads on choosing a 5 channel amps but most of them advised the OP in going with a high end and expensive model such as the Alpine PDX-5. As much as I would love to buy a PDX-5, I just don't have the budget to spend that much on an amp :(. So what I've been looking at are sub-$250 5 channel amps and these are the ones that I'm the most curious about.

As we all know, Maxxsonics is the parent company of MB Quart, Hifonics, and Crunch. Unfortunately for people like myself, the same company offers three different 5 channel amps under three different brands. This makes it hard to speculate if there is a jump in quality going from Crunch to Hifonics or from Hifonics to MB Quart. Maxxsonics does, however, make three very budget friendly 5 channel amps that seem to have pretty promising numbers on paper.

I honestly wouldn't mind picking up any of these amps under the condition that they are not specifically known to be prone to problems.

The Crunch P5000.5 is a steal at $149, granted that it works well and doesn't overheat. The power numbers are strangely listed at peak power and Maxxsonics has advised that the RMS is roughly half of the listed peak power. At only $149, it's kinda fishy...that's where the Hifonics Zxi8010 comes in. Would the extra $50 net me some extra quality? And if I step up to the Hifonics Zxi8010, what's keeping me for paying $30 more of the MB Quart PAB-5400? You see this is what is frustrating, three products made by the same company with very similar numbers with less than $50 price difference between each of them. I mean how do I know that when I'm paying $80 more for the MB Quart PAB-5400 that I'm pretty much not getting a Crunch P5000.5 with an aluminum case?

Personally the two that I'm looking closely at are the MB Quart PAB-5400 and the Powerbass ASA-700.5. I'd be lying if I were to tell you that it isn't because I'm drawn to the aesthetics...because it is. But other than that, I'm hoping these also have a bit more quality in them. But when it comes down to it, if the Crunch P5000.5 works perfectly fine and has no glaring issues...that is what I'll be picking up for $149.

If anyone has any insight on the amps listed above...please please please chime in and make my decision a little easier because right now it all seems like a crapshoot.

I've been thinking about these amps too. With the first 3 amps you posted being from the same parent company how different are they really on the inside?

Sometimes you pay for cosmetics, sometimes tuning, sometimes quality... I have no idea

Look into the jbl 755.6. It's a 6 channel with a pair of class d channels that can be bridged for an underated 300x1 or something like that. I ran one for a short time and it did the job nicely for the install and goals it was presented with.

Out of your original choices I'd go with the powerbass.

Are you hung up on buying a new amplifier?

nicer stuff can be had.

What power do you need/want and at what price?
Yeah I'm shopping around for new amplifiers (4 channel and mono) and was curious about the 5 channel solutions. My price range is less than $250. Power wise I need something in the area of 50-70 x 4 and 300 x 1 RMS.

I just thought I'd get some input one some of the amps I listed. I've found that alot of people are curious about them because of their specifications and their pricing. I've kinda consolidated all of the cheaper 5 channel amps in one thread because there are tons of threads about each of them but it seems like none of them get a clear cut answer on how well they perform.

Look at HI-FI sound connection. I just picked up a Kicker zx700.5 referb for $230 shipped. I was considering the Hifonics and MB Quart myself until I ran across the hi-fi site. Kicker ZX700.5 ZX Amplifier Car Stereo 1520 Watt Multi-Channel Amp
I almost included the refurbed zx700.5 in my thread as well but the refurb part had me kinda iffy. Refurb stuff only carries a 90 day warranty which honestly isn't that much time...still $230 for a zx700.5 is very tempting. How long have you had yours? Did it come with a birth sheet like all of the other kicker amps? If so, what kind of power does yours put out?

I would have to agree with Hillbilly on taking a chance on the Powerbass amp. The quality on the other units are suspect in MHO. Not saying that there not any good, just not sure.

Hillbilly provided a much nice amp in the JBL.

The kicker would be my second choice - they do come with birthsheets, but ignore those

Powerbass is third

The birth sheet that came with my ZX700.5 tested at 900 watts total power at 4 ohms. I've had mine for about 3 weeks and have been waiting for the weather to get better to install it. This weekend looks promising :).

LOL! That looks a lot like my setup. I am swapping my DEH-P5900IB for an Eclipse CD7000 so I can go active on my front end and I just got that same sub.

All things considered, they are all pretty much in the same class and performance envelope. In fact I wonder if they are all the same board and parts inside.

$250, eh?

How about a surprise contender? The Scosche EFX amps are at or under your budget, but should perform admirably. At your price range, you can actually get a LOT of clean power. The HD1800 mono is capable of 1ohm loads (but does fine w/ 2ohm too), and runs a measly $149. The HD1400 is only $99 but makes more power than the other amps you've selected here. Its match, the 4ch HD4300, will serve your other channels with power to spare, or you could go up to the HD4600 for a few bucks more.

The money left over could be spent on getting you out of Infinity "abortions" for speakers. :) J/k, that's only my opinion.


Here's the amps

How much room do you have for amps? If you have the room, Fourthmeal's suggestion may not be a bad idea. You could get more power to your sub that way as opposed to the output of the sub channel on a 5 channel amp.

Thanks for all the help guys! I'm glad I stumbled onto this forum...you guys are super insightful!

I've actually looked at the Scosche amps before I stumbled on 5 channel amps. I think there are many reasonably priced and adequately powered 5 channel amps that I might as well get one since I like the idea of one amp to power my entire system.

Haha at Fourthmeal. When I first got my car I thought it'd be cool to have Infinity speakers in my Infiniti car and my friend worked at bestbuy and got me crazy good deals. Personally I'm happy with them...though the highs are sometimes overpowering and too tinny and the midbass is somewhat lacking.

I think what it comes down to is the Refurbed Kicker zx700.5 or I might go out on a limb and try out the Powerbass ASA-700.5.

There's no problem mixing different ohm speakers on these amps right? Like if I wired 4 ohm components and coaxials and then a 2 ohm sub up to it.

And thanks again...you guys rock.

As much as I hate to say this(sigh), I would go with the Kicker.

Mixing ohm loads are how 5 channel amps are made to work, so 4/2 ohm is perfect.

If not the kicker, seriously look at the directed I posted. Its a very solid amp with a powerful 4 channel and class d section. I used it (previous model) for a few years in my last car.

For the price I would take it over the kicker for the more power but either are the really good decisions here.

I dont know why youd take a chance on the powerbass when you have the kicker or directed option for the same price.

Considering you have a 2 ohm sub, you really want a class d channel with these inexpensive 5 channel amps. Other better options are not available in your price limit. I wouldnt recommend running a 2 ohm sub on any of your initial choices. Even though theyre rated 2 ohm stable, they tend to overload often when driven hard. Talking about the maxxsonics (mb, hifonics) specifically.

Directed or the kicker ftw

Unless youre open to two separate amps I dont see a better option.

So Id recommend a class d sub and 4 channel a/b amp instead of all the 5 channel a/b classes because of your sub.

Your options under $250 then are:

Kicker
Directed
Infinity posted earlier
And the JBL if its class d

But seriously, take a look at this one

Is the car deadened yet?

If not, expend money on that.


Now then, 5ch ONLY, eh? BTW, I think that is a BAD idea unless you need the space savings. Why? Because you are putting all your eggs in one basket, so to speak. Amp fails, you're done. If one amp of a 2 amp system fails, you're only 1/2 screwed and you can buy another amp.

Anyway, place a bid on this thing, hopefully you can snag it relatively cheap.
