Reccomend me a 4 channel amp

Good morning fellas. I'm in the market for my third amp for the truck. Let me give you the low down. I originally ran the door speakers off the headunit until I added the sub. The headunit did an alright job but couldn't really keep up. So I added the first amp which was a blaupunkt unit. Severely underrated that unit put out a clean 85 watts rms according to a few o-scopes. That lasted 3 years and finally started going into protect mode but holy crap did it have clean power. I replaced that with a JBL unit that never sounded as good and ran roughly 70 watts rms cleanly. That made it less than a year before it went into some random state where the output would drop and get all distorted at a normal volume that happens to be a listening level when you're on the highway and is getting progressively worse to the point where I can't even enjoy it anymore.

So now we're here. I would like to know what you reccomend as far as a 4 channel amp that I can fit under the drivers seat that pushes around 60-80 watts rms. I would prefer class A/B only because having the mini amp in the envoy I could hear the difference between that and class D but... I would imagine that a good class D sounds fine. I also don't want anything crazy expensive either. Under 400 or so. I was looking at Rockford, focal and MTX on their more entry level stuff but I overall wasn't extremely impressed spec wise... I know it isn't the be all end all but it's a decent way to go when you can't listen to them all.

Any input is much appreciated.

Mildly surprised that no one replied before now.

This is my non-scientific opinion, but if you've gone through three amps in the 70-85w RMS range...maybe you should look at something that has more power, but you wouldn't have to drive as hard. As someone told me long ago... 10% of 100 is going to sound better than 100% of 10 (even though it's still 10 watts, in either case.

It's gonna cost you more, especially if you want class A/B. Not sure what the warranty is on something like a JL Audio, but I'm thinking that's the type of amp you might want to look at. Something considered dead nuts reliable. Hopefully, JL still is in business - I'm going from old-school memory off the top of my head.

Another idea - look at something you can bridge 2-channel, and run a front soundstage + sub. With something like this, you could get a lower-wattage amp (but you'll be driving the output twice as hard, so...)

As far as the brands you listed...
Rockford - pair great with their speakers, otherwise, so-so.
Focal - speakers sound nice - but I'd never pay that kind of coin. I've heard them on multiple occasions and have 'picked' them a couple of times, if cost was no object (and this was when I was making decent coin.) I don't know that I've heard their amps, lately, but if they're like the speakers, they probably sound pretty good.
MTX - more entry level, but if they have a good 2-3yr warranty, might be worth a try.

If you want to try a class D, give Pioneer a look-see.
I've had experience with Alpine; those are good, at least when I had them.

Finally...what are you using for speaks? If it's something 'really good', they may need a good amount of power to drive them properly.

JBLs in the rear doors and a set of JBL components up front. Not high end but not entry. It's their mid level setup. I've always exceeded rated rms by a fair margin when I selected components and the speakers them selves are claimed to be rated for 65 watts rms. (But they seem to sound better when I didn't have the gain pulled back on the amp)

The first amp spent 90% of its life screaming so I understood that. But the replacement really wasn't abused all the much which is what bothered me. The speakers are some oddball 3.2 ohms or something like that but everything was 2 ohm stable so I never really bothered digging into that too. I'll give JL a look as well.

Very much appreciate the offer. However, I think my aunts and mom will actually kill me because as of now, it's like the only thing they have to go off as far as a Christmas present. :weird: So, I'll say keep it for you for now.

I'm a pioneer fan boy, currently eyeballing a 5 channel they offer. I don't have a lot of their stuff but what I do have is top notch and I'm sold on them for brand (all except subs, I have beat and abused my kickers and they're still kicking. Over-wattage for 3 years straight, only smelled them once lol)

My sub is actually a pioneer... well its RadioShacks house brand from the 80s which was made by pioneer. Kicker makes decent subs. For the money you can't touch them lol.
