Question about Alpine 12" Single-Voice-Coil 4-Ohm Subwoofer

1 Answer

3 subs in one month.

I have gone through 3 Alpine e 12's in one month, the first one I bought lasted about a week and then just died, didn't blow, died. Exchanged it for a new one, same story, about a week later it was dead. I tried once more, having nothing but good stories and experiences with Alpine in the past I was hoping it was just a bad batch. This one lasted just under a month, then same story. I had the subs in a single sealed box with an MTX RoadThunder2160 450watt max 225 RMS amp, which like all amps will overheat but i have never even blown a fuse on the amp, it pushed a JL Audio 12 for over a year without a problem, why are these alpines dying on me left and right?

    would adjusting the high pass filter in the reciever help to prevent these subs from frying out? With my JL I kept it at a constant 125, and it never had a problem, but with the Alpines I pushed it down to 80 and never even thought about it, or would the eq on the amp be pushing too many high frequencies? And what is this scope you talked about?

When you say these are dead, is the voice coil open? If so, the easiest way to fry a coil is to send it high frequencies that it can not reproduce or to send it a distorted signal. If you know anyone with a scope, scope the output when you have it running. Normally the low end will be a relatively smooth curve. If the curve is made up of a really jagged line, you may be passing harmonics through the amp that can heat up the coil causing it to fry. Check the output of the amp with a volt meter. When cranked up you should get no DC voltage at all. If there is DC, that too will do nothing but heat up the coil.

Keep us posted.

    80 is fine. There is something else going on. When you exchange these speakers, do you get any idea of what failed in them at all? That would help to determine the cause. Check the terminals of the amp for DC voltage. That is where the problem resides I suspect.

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!

if the wiring to the sub is correct, then you have something wrong with the amp itself... something is power surging to the subs which is causing them to blow

Have 4 - 12 alpine type R in custom box made just for them. Hooked up to a JL 1000 slash 1v2 mono. They all have power but when i really crank it one of them pops a little. Theres no way that amp could be...


It may not necessarily be pushing the subs to the blowing point, but you amp may be clipping. If you amp reaches a certain point where is strains for power, it cannot reproduce the frequency. The result is a "popping" sound. Your right in that the amp couldn't be doing that. Another thing to check is what is the ohm load on the amp. Is the amp 2 ohm or 1 ohm stable. You could be damaging the amp if it is not wired correctly. Hope this helps.

Internal damage to Mirage BPSS-210 Subwoofer amp


Something getting hot probably means something shorted out. You probably know that since you replaced the fuses already... . Can you give me some idea of what you do and do not know about electronics? Then I will say fewer dumb things. . When troubleshooting any electronic device, especially amps, open it up and look at the circuit board. Look for burned board and components. Then test to see if the burned/blown component had reason to blow (it probably did). . Often a shorted transistor runs too much current through some other component and the other component blows up. . Another cause, less common, is a shorted cap. . Look at the schematics if you have them, if not, you may have to create one to make sense of it. . Or take it to a shop where somebody does this all the time. The only one here went belly up in the last 12 months... . . About the pots . Try blowing out the pots which are popping with some tuner cleaner. Use with caution, and always with everything turned off and power cords unplugged. . Pots do not usually make popping noises unless they are very old or live in a very dusty place... . I found the manual, but no schematics... http://docs.google.com/viewer?a=v&q=cache:9Doi39-AcW0J:www.miragespeakers.com/images/download/374.aspx+Mirage+BPSS-210+schematic&hl=en&gl=us&pid=bl&srcid=ADGEESjBKgLSTb8wp5SRWIOWd-gE0INdBXbfz5QDNJ_3esye4_R2Q9aKba8cEePSWQWOebeXB9zXnJSelIel2bLSR5q6KExe8MVjOk1zqFKk4K-ruti_797yf1Ig3CIcUNjE49jx8DAr&sig=AHIEtbS6udedt_o6GqL7ALPunU0v3vMvuw . You might be able to get better, more exacting help on the Mirage Forum... http://community.miragespeakers.com/forums/ But maybe not, since the Subwoofer section gets less than one post per month, and the much busier Technical Questions section only has 23 in the last 12 months.

Is my amplifier giving my subs the full power they need?


no sony has like 400 rms on that amp. eventualy u will blow the subbs. buy the hifonics 1608d amp to power thees subbs connect them all positives together at amp terminal and all negative together at negitive on amp terminal. this will make it a 1 ohm load with around 1400 true rms so around 500rms each sub.this amp on ebay runns like 250 and is worth every penny

I have a set of Alpine Type R 12 inch subs... I have a 1500 watt amp powering them but when I turn the music up, the bass cuts out. Where should I start looking for the problem?


ground is loose(most likely amp), battery running low, subs might be damaged? feel free to keep me in touch if problem occurs more after checking grounds and power source and subs. Also might need to re-tune your head unit and amp?
