Question about Alpine MRP-M850 Car Audio Amplifier

1 Answer

Wont turn on...

My Alpine 850 wont turn on.. I set up just a cheap little amp that pushes 130watts rms to my high range front speakers. Unfortunately i played them a little loud and the speakers blew also cause they were old. But my problem is i had 2 amps in 4 gauge wire to 2 8 guages then it was after the speakers blew the subs the amp stayed on for a bit but then the amp shut off and i thought it would come back on but it didn't i checked all the fuses and they were good i'm really hoping its not deffective cause i dont wanna buy a new one -.-'

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I have 2 6x9 speakers up front 4 6 1/2 3-ways


Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

What speakers


Hello enot99,

The CC-2502 is a bridgeable 2-channel amp. If you want to drive normal speakers in stereo, the best would be a good set of components with separate woofers, tweeters, and crossovers. They are available in many sizes from most car audio manufacturers. I'd begin by finding out what speakers fit the location where you intend to mount them. Then I'd browse the speaker selections in that size at www.crutchfield.com. You can also use the "outfit my car" feature to browse only the products that fit. Then select a pair that has a power range and impedance to match the amp: 250 watts RMS at 4ohms or 450 watts RMS at 2ohms.

If you want to use the amp in bridged mono mode to drive a subwoofer, again Crutchfield has a large selection of subs and some enclosures already fitted with subs (loaded). The amp claims 850 watts RMS into 4ohms bridged, so look for a sub that has a power handling rating of at least 850 watts and it needs to be 4ohms.

Hope this helps.

Installing two amps


No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

What amp will push 2 kicker 15inch cvr's


Hello herb31,

Kicker lists the RMS power handling range of the CVR's from 100-500 watts, with a peak power capability of 1000 watts. There are lots of monoblock amps within that range. It just depends on how loud you want them and how much you want to spend.

In the low range, an amp like the Alpine MRP-M500 will deliver 250 watts to each sub at 2 ohms. And it only costs $179. Currently, the MRP-M500 is out of stock at Crutchfield. I just bought the last one. So my 2nd recommendation would be the Sony XM-1S, which has the same power rating and according to Crutchfield is no slouch either. It's also $179. I really like the Sony, too. It has a small footprint that makes it easy to find a convenient mounting location. Both the Sony and the Alpine are CEA-2006 compliant, so you can be sure that the manufacturer provided specifications are not overrated. Assuming that your vehicle electrical system can deliver the current, both the Sony and the Alpine will deliver an honest 250 watts RMS to each of your Kickers. And 250 watts will make them kick pretty darned good.

In the medium power range, consider either the JL Audio G Series G1700 which delivers 700 watts into 2 ohms. It costs $419 at Crutchfield. Or perhaps the Kicker 08ZX750 with 750 watts at a cost of $399.

To push the CVR's really hard, close to their 500 watt RMS maximum power range, look for an amp that delivers 1000 watts. In this range, you will definitely some heavy-duty wiring, electrical system upgrades, perhaps a 2 farad capacitor, and be ready to spend at least $600 on the amp. Your best combination of power and price would be another Alpine, the PDX-1.1000M, at $799. If you buy one from Crutchfield, they will throw in a 4-gauge amp wiring kit. And if you use a "friend referral code", such as mine, which is p7sdj-hrx8q-9800g, and your order is at least $200, you'll get another $20 discount. And I get a $20 credit toward a future order.

Hope this helps. If it does, please rate as "FixYa".

550x2 subs....SPL z2x-820 Amp


Hello,

The 230 watt amp is a little small for your subs. They'll work, but if you are looking for max SPL, you won't get it. To push those Audiobahn's to their potential pavement shaking max, I would recommend an amp in the range of 500-600 rms (2-channel bridged) or 1000 watts rms monoblock.

Hope this helps.

When the bass cut on the speakers cut off


220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.
