20 Most Recent Alpine MRP-M1000 Car Audio Amplifier Questions & Answers


Is the amp in protect mode? Maybe a red light on the amp. I would also open the amp and check the RCA connections aren't loose. It's usually a solder joint. Swap the amp out as well. Or check your power wire. Sometimes amps come on when it gets remote power, but actually the power wire has a bad fuse or connection.

The amplifier may be going into protect mode (even briefly) because you are driving them too hard. Back off on the volume and see whether the problem goes away.

ok its all in the way you wire them, just remember when you wire your speakers in series, the ohms build(add to eachother) which would make them total of 8 ohms, and if you wire in parrallel the ohm load cuts in half (2 ohms). So you want to wire them together in parrallel then run your wire to the amp. Just so you know though, if you bridge your amp, it will also cut the ohm load in half, so you would see total of 1 ohm which gives you more power, just make sure your amp is 1 ohm stable and your subs can handle it.

Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

Where is your subwoofer gain set? Also, what crossover frequency do you have the sub set to?
