will this be a good amp for 1 rockford p3 12? and if so which will be the better fit? the 2ohm or 4ohm sub?

Rockford Fosgate P3D4-12
Best Answer: Hello,

Your answer is in the specs. =]

Two Rockford Fosgate P3D2/D4-12 will be asking for 1200w RMS. The MS-A5001 is only able to produce ~500~750w RMS @ 2ohms. So, although the MS-A5001 is a Fantastic amplifier, it is only able to put out enough power to drive One sub at its full potential. The best match for two drivers will be the Rockford Fosgate R1200 or NVX JAD120.1; of which, will need the Dual-4ohm version wired down to a 1ohm load. If you wish to go with the JBL amp, you will need Two amps and the Dual-4ohm drivers wired to 2ohms respectively.

Does this include remote control for bass and volume?
Mnnmat on Feb 11, 2015
Best Answer: Hi,

The MS-A5001 does NOT ship with a Remote. However, the JBL MS-WBC is the compatible remote for it. Unfortunately, we no longer carry, it is discontinued, and we aren't sure where you will be able to find one. However, we suggest taking the model number and doing a quick search. In the even you do not find one, we suggest going with a Universal Remote Level Control, which may very well be the best/practical option anyway. We us the NVX XBRC in our Install Bay when faced with such a scenario.

This amp does not turn off after the vehicle is off. All settings lost when the ignition is turned on. Please help.?
A shopper on May 4, 2015
Best Answer: Check your wiring. Use a multimeter to verify your positive reads 12v always, and that your remote only reads 12v when the car is on, or the key is turned to acc. If everything reads correct, then I would suspect that you may have a bad amp. However, it sounds like a wiring problem.

Does it matter if this amp is mounted in a flat position or a vertical position? Read the whole manual and it did not say. Thanks in advance
A shopper on Oct 23, 2015
Best Answer: Hello,

I have this AMP installed vertically but don't think it matters how you mount it. As long as you give it at least 1" for ventilation all the way around.....

Would the amp pre out put a full range signal to daisy chain a two channel amp for component speakers?
A shopper on Jul 4, 2015
Best Answer: No cause the rca cables coming from the deck only hold a subwoofer signal. You'll have to run separate rca for hpf (high pitch frequency). Same with any and all amps.

Does this amp have enough power to push two 10'' gto1014d subs?
Andrew L on Apr 12, 2015
JBL MS-A5001
JBL MS-A5001
Best Answer: This amp will not work for those subs. Since they are dual voice coil, you need to find a sub that is 1ohm stable, and preferably bridge capable. Wiring the voice coils in parallel with each other in each sub brings each sub to 2ohms, then wiring the two subs in parallel it's the amp makes a stable 1ohm system. This is the best possible way to get these subs to hit hard and tight like a kick drum or an 808 bass drop. Don't put too much power into them though. I put 750watts through mine and they blew. Obviously. Keep it at 450-500watts at 1ohm. Hope this helped.

What's the best way to wire these subs? 4 ohm to 2 ohm or keep it at 4 ohm?
Logan H on Jun 25, 2015
Best Answer: It depends on the sub and the Amp you are using....If the Amp is stable at 2 ohms then you could wire it and see if it thumps...Otherwise, keep it at 4 ohms...
Read the manual on your Amp.....Always wire per manufacturer's recommendation!

I'm looking to power the polk db1222 dual 12" 2ohm enclosure. Would this be a good amp?
Ruben G on May 20, 2015
Best Answer: I think you would be pleased with the amp performance, I'm pushing 2 10" JL's in a Stealth Box in my Camaro at 4 ohms, and don't have it tuned to its full power. The digital interface is really nice, and makes adjustment a snap. Hope this helps.

Does this mean that it has a built-in line out converter?
Ryan D on Dec 22, 2014
Best Answer: Yes, There is a pair of RCA output from this amp and you could connect another mono amp from that output. So, for example, all you'll need is a pair of RCA from your head unit sub woofer output into one amp, then another RCA from that amp output RCA into the other amp input RCA. Hope that help and make sense.

I just recently installed it for the first time. Everything is hooked up to my factory system. My issue is when I turn my car off the amp send a "test signal" every time to my subs, causing them to bottom out. According to the manual I should be able to adjust the level input to prevent this. However every time I try it still ends up doing it. Any suggestions?
Chad P on May 28, 2017
Best Answer: Toggle switch to power off the amp before turning off the car or radio. Cheap and easy solution.

Other than figuring out another way to get the amp to power down at the same exact time or before the OEM radio, as it sends a voltage spike upon powering down that your amp is amplifying for a split second before it loses power itself.

I know it's not optimal, but if I use my vehicle's head unit speaker leads running to the stock rear speakers to feed this amp, would I totally disconnect leads from stock speaker, or just tap into them, leaving the stock speaker hooked up?
CohoCarl on Aug 19, 2015
Best Answer: Hi

If you are using the rear speaker wires from a stock deck, you are tapping into the rear sound and you will still get the left/right sound out of your stock rear speakers. If you want to just use the rear wires for a subwoofer then you have to disconnect rear speakers.

The other option is tapping in directly from the deck output wires and running a separate wire to the subwoofer. You would still have to connect rear subwoofer RCA's from pre-outs of the stock deck.

Best Answer: Just depends on how you wire your subs. Dual voice coil subs particularly these can be dropped to 2 ohms. Pay attention to impedance matching.

If I am using my factory amps sub channel as hi level inputs does the "auto sensing " feature mean I do not have to run a dedicated switched 12v wire as a remote turn on?
Dcfis F on Sep 19, 2016
Best Answer: Yes, it is supposed to be sound sensing, and you can adjust the sensitivity as well.

These amps have a set up CD included. I plan to run a tablet as a head unit and input to amps via jl Audio mbt-rx Bluetooth connection, do I need to see up the amps with the CD software in order to use them or do I have FULL functionality without said software?
Jeff S on Jan 17, 2016
Best Answer: Hi Jeff,

The Setup CD does not include software - it is basically test tones to setup the levels appropriately. To your point, you are not obligated to use it.

is the jbl 5001 mono block power hungry or very efficient i want to put it in my 2011 dodge charger i currently have a ssl 1500 mono block it hits ok but not the way i want i no the power rating is low on this amp?
A shopper on May 8, 2015
Best Answer: Hello,

Compare to any SSL amplifier, literally Any, the JBL MS series is Very efficient. Coincidentally, it likely makes better power , being CEA Compliant, than that amplifier as well. Even if the latter isn't true, you will be able to keep your power for a longer period of time, which, in of itself, makes the MS a better option.

Do the audiopipe 1500d mono takes a lot of power I have a 1997 suburban I running 4 guage 3,000 watt amp wire and do I need a dry cell battery with this amp I have a 2 frag cap already?

Audiopipe APMI-1500
Audiopipe APMI-1500
Best Answer: Hello,

The amplifiers are fairly power hungry, but not comically inefficient by any means. It really depends at what impedance you wish to run the setup at, but if we assume the lowest possible load, providing ~1400w, then you may require some upgrade in components. A proper battery will absolutely help, but you won't know until the amplifier is in the vehicle. A capacitor is not intended to help your vehicle, so if that is your main concern, don't bother with the cap.

Also, 4 Gauge is not intended for a "3,000 watt amp". Even very high strand OFC wiring in a VERY short length is only able to properly handle Half that. So please plan accordingly. Coincidentally, assuming OFC, 4 gauge is perfect for the APMI-1500.
