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!

What is the best amp for one 15" alpine type r?


sub spec 250watts per coil you should be just fine I have 2 typr 15s on orion hcca 2500 1 and it kicks a$$ thats 1000 watts over the rated limits of the subs only shut the amp down once these subs can take a lot more power than they say just use your common sence with the volume and gain levels

I have the MRP-M1000 amp. I want to hook up 2 alpine subs to this amp. Which alpine subs would be the best for this amp? Please be specific with ohms and watts.


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.

I haw alpine mrp-m350 amplifier how many sub can i


Hook up the MRP-M350 to one 4-ohm sub, and you get 200 watts RMS; connect a second 4-ohm subwoofer and the power output increases to 350 watts! All that juice means that your subs won't just be loud, they'll sound clean and thumping.

I am wondering about car amplifiers, I don't know what kind to get, I have Alpine 6.5" 2-Way Car Speakers (SPS-600), 80 watt as my front speakers, and Alpine 6 1/2" 2-Way Car Speakers (SPR-17C), 100 watt...


I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck

I have one 12inch 1000 watt mtx sub what size amp should i buy


Hello taona80,

If the 1,000 watts is RMS, I'd recommend an amp in the 750-1,000 watt RMS range, perhaps like the Alpine MRP-M1000 or Rockford-Fosgate T1000bd. If the 1,000 watts is peak power, the subs continuous (RMS) power handling is much lower, probably 300-400 watts. In that case, I'd recommend the Alpine MRP-M500 or Rockford-Fosgate T500-1bd.

What is the best way to wire two alpine SWR 1222D subs to a alpine PDX 1000 1


First off excellent choice on audio equipment, i guarantee you won't be disappointed. So your subs are dual coil 2 ohms. So wire each individual sub in series. If you don't know what this means i'll explain. On each sub there are 2 sets of wire terminals. Connect a wire from the one set's - to the other set's +. Do this on both subs and you will have the coils wired in series making each sub 4ohms. Now to hook the subs together you'll need to wire them in parallel. Now since you have your coils in series, on each sub you have one + terminal and one - terminal left. So run a wire from the + terminal remaining on each sub, and run them to your amp. Splice the ends of the two wires together and plug them into the + speaker output of the amp. Connect the two negatives in the same way and plug them into the - port on the amp. You will now have your amp running at its desired 2ohms. When wiring this disconnect the fuse on your amp power wire to avoid short problems. And if you get confused at all, and aren't sure what to do, ask again don't guess, if its done wrong you could severely damage your equipment. Hope this helped, enjoy the bass...

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

Alpine amp and subs questions


it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation
