Alpine amps?

Since all my Jl audio stuff got jacked and the insurance isn't paying for I'm looking at going a little more cost effective route.
I've always used the alpine head unit and type R speakers and subs and been happy with them so thinking about going with thier amps too.


I'm running 4 5x8 type R's in the door and a single 12 sub.

Anyone used these amps or have any input on them?

Though about maybe going this route too and just having a single amp.

i have that last 1 but mines a 600 watt that i use for my 2 jl 10s. works pretty good to me. that last amp should work just fine for 4 5x8. they will be getting 75 watts each and that plenty loud unless you want ridiculous loud then you'll need more power of course.

i used to run an older series of alpine's vpower amps.

a 2 ch mrv-t320 powering 2 type r 6.5 components
and the mono mrd-m500 (still got that one sitting around) pushing a 12" type r

i liked the setup a lot. it was very clean.

i was told alpine were great amps for mids and highs but not so good for bass. but this was about 7 years ago. not sure now.

Why would that be? It doesn't make any sense.

Alpine's older stuff is nearly unstoppable. I'm still running a 3554 (50wx4) that I bought from Sound Idea in 1990. It's powering a pair of Polk Audio 5501 5.25 mids and a pair of JBL T06 titanium tweeters up front, and channels 3 and 4 are bridged, powering a single Petras 10" sub. The speakers are all from 1990 as well and the whole system has been in several vehicles over the years.

At one time, I used a 4Ch VPower amp with a built in bridge and x-over to push 2 8ohm Kicker 15's in parallel. It was a very effective setup to run the rear channels cleanly while pushing the subs plenty. Unless Alpine's build standards have decreased, I would not hesitate to purchase one of their amps again.

My favorite amplifiers were the old Orion HCCA's. Unfortunately, I think they quit making those a long time ago.

i have an alpine v12 4 channel amp powering the focal door speakers in my car, and a jl 500/1 for the subs. i am very happy with both.

It has to do with how much power you with little distortion. Most alpine amps aren't terribly powerful, but they're relatively clean. You can get away with less power on mids/highs, but you'll obviously lose some output. On subs, where you can mask a little bit of distortion due to frequency and subwoofer position, the lack of output is very apparent.

Clean power is clean power. Most alpine amps don't have much of it, with a few exceptions.

I have a pair of 225HCCA's in the closet, still brand new in the box. Baddest 50 watt amp ever built. I ran a pair in one of my old competition trucks back in the day, pushing 12 15's. 1/2 ohm stable operation FTW! Just for the record, the HCCA series is still in production. This one is rated at 1250w X2 at 4 ohms and 5000w X2 at 1 ohm - http://www.orioncaraudio.com/Product...?ProductID=573

There are 100 other amps that would put more power out and cook less stuff than that old HCCA. Unless you plan on competing in a power restricted class, then I would sell it to someone who is.

That's what I used them for before. One of our cars had the entire system running off of a single 225. The looks on uninitiated peoples faces were priceless. All that sound coming from just 50 watts?! They don't make the 225's anymore, so I'll hang on to them. Never know when the itch will strike.

Yeah, but people don't understand electricity. So the "25x2 @ 4ohms stereo" is a hell of a lot different at .5 ohm mono... I'll stick with an amp that makes its power at a reasonable heat level. Those things were unreliable back in the day because of the heat they generated at ridiculous impedances.

MRP amps are ok. I run them (the F300 and m500) in my niece's car. 50x4 @ 14.4V 4ohm is not that much power. PDX-5 is better but 300W on the bass is just ok imo. JL XD400/4 and XD600/1 would be my choice for budget system but will cost more. Or, you could use a PDX-F4 running 3 channel and get way more power on the mid/high but around 250W on the sub.

Nope. Less than 50W rms at 4 ohm (which is what he would be running on 5x7's) and my guess is more like 40W rms @ 12.5V.
