Re: How to install this amp properly?

The amp is a mono amp with only one output channel so it cannot be bridged. You'll use one positive and one negative per speaker. The positive speaker terminals are connected together and the negative speaker terminals are connected together so it doesn't matter which you use for the individual speakers.

How can i wire an audio pipe ap30001d to my two 15 inch alpine type r 4 ohm subs

This is a D class amp ,which usually means it will run @ 2 ohms with no problem .The issue is that the Type R subs are dvc and 4 ohms per voice coil ,there is no way to get a 2 ohm load to really make the amp perform at its best . I speaker parrallel will work the amp harder than both subs ,If you run the amp at 4 ohms it will work and probably not even get warm ,I would series parrallel The way I would do it is on each sub run a wire accross the + terminal and the opposite - terminal the remaining + and - terminals from both subs wired together to the according + and - terminals at the amp ... this will read 4 ohms at the amp . you can try wiring all + and - together to + and - terminals at the amp ,this will be 1 ohm and will probably be loud as hell ,but you risk the amp getting hot and shutting down ,If competing and short burst ,probably ok for a few minutes . 4 ohms will run cooler and much longer .

I have a boss rt645 2ch 1400 watt amp would this amp properly push a pair of 12 inch mtx terminators.

That all depends on the wattage of the subs. also the independance of the subs. If your amp is 1400 watt, maximum you want is 2 600watt subs. if your subs are higher you will blow your amp eventually as your amp isnt powerful enough to pump out to that level.You should never have your amp fully turned up to max, 80% is perfect and will not make your amp blow. Hense why you want your subs less than the max output of your amp.

How do I hook up a sub woofer to my 52wx4 radio. I

You can hook it up a couple of ways.
Depending on how many subs you have and what ohms they are running at here is the chart you need. If your going to run one sub off it the last option is the way to go. Your going to need to find out the power of your subs or else the power could be off and you could blow the sub. If the rms power is higher than 130watts per coil you will be fine. If so there are four channels on the amp and two should show a line going to each other that says bridge. Hook up the positives and the negative of the subs as shown on the amp that will get your max power. If your sub is running at 4 ohm. Let me know, if not thats how you would do it.
Also for the power and remote wires. Hook up a power wire (16 gauge would be plenty fine) from the battery to the + terminal of the amp. Then take an equal or bigger sized wire from the - side of the amp and secure it to any medal part of the body of the car. If there is paint on it get if off. (not on the outside of your car or where any water would be.) Then run a remote wire from your stereo (most the times it is blue and white) to the remote terminal of the amp. This tell the amp when to turn on and off. Your amp will not turn on with out all of these wires. Good luck to you and let me know how it works out.

    Lights up & getting no power to subs

    for a test
    disconnect everything from the remote terminal in the amplifier
    get a bit of wire and connect the remote terminal to a 12 volt supply
    does it turn on now?

    if yes then check the remote wire from the radio does it become 12v when the radio is on and 0v when it is off

    if no make sure that the amplifier has been grounded properly and all the power cables are connected properly

    I'm planning on installing a system in my pick-up and I was hoping I could get a little assistance. I was planning on using a pair of 5'' McIntosh ms486 coaxial speakers (120w max 4 ohm)in the front doors...

    First of all use the larger output amp to power the sub. You can tell if its free-to-air if in the middle of the magnet there is a hole for "air" to flow freely. The advantage of free to air is they dont require much of an enclosure or next to none so you can mount it on a single piece of mdf wood and use the cab in the truck as an enclouse itself. I would bridge the amp for the sub to mono but be careful to tune so you dont "distort". Secondly the amp for the mid's shouldn't be bridged any maybe you could run the front and rear speakers off the same amp.. I would get an amp for rear and front speakers each and one for the sub. Your ouput rca's should goto the cross-over first then to the amp (sub) - then wired to your sub (mono) which is bridged. Ensure to tune your cross-over to lowest frequency for sub. Its easy to bridge an amp if its 4 channel.. looking at the speaker terminals it will look like ( + - + -) use the two outer most terminals to bridge to mono.

    When i turn the volume up high enough one or both fuses on the amp will blow.

    This most likely means your amp is blown. All you can do is make sure your battery and ground wires are tight. Also double check to make sure + and - Speaker terminals are going to proper terminals on amplifier. Thanks

    Playing music for about 2hours and bass amp shuts down

    You have maxed out the amp! if your running one 4ga. pwr wire to all your amps, it's choking. Going to Wendy's buying a frosty and sucking it thru a straw!. Your amp is starving for more Voltage and current. That amps peak output is 1200w @ 1ohm, not too shabby! Now onto the next issue: Grounding!, just as important as power! Your amp MUST be grounded properly. Don't ground it to a seatbolt or side wall of the vehicle, go directly to the floor, hopefully less than 2-3ft tops. using the same gauge wire as power. If your power is longer than 12 feet, and in most cars it is, you loose alot of voltage and current flow to the amp the longer the run, the more you loose. That's just how DC power works. What's happening to your amp is it's working itself to death and creating massive amounts of heat. "enough to cook dinner" Run a 2ga or 1ot power wire to a distribution block at the amps. Wire in your other amps, then use the stiffening cap just for the sub amp. Not a cheap answer but it will solve most of your problem. Next, set the gain on the Sub amp NO HIGHER than 1 o'clock. Beyond this, and there's no help for it, there's no more gas pedal to push!. Enjoy your system but don't kill it! Hope this helps

    I cant hook up my amp

    Hello cesar199064,

    These are the steps you required to install your amp and subs:

    1) Purchase an amp wiring kit with 2 or 1/0 gauge power and ground wires.
    2) Decide on a location to mount the amp where it will get proper airflow and will not interfere with operation of the vehicle. Closer to the battery is better. Decide on the location and install the sub enclosures.
    3) Locate a place on the metal body of the vehicle within about 3" of your amp for the ground. Connect the ground wire to the amp ground terminal and to BARE METAL on the vehicle.
    4) Run power wire from battery positive (+) using one of the amp kit ring terminals through a 100A fuseholder to the amp positive terminal. DO NOT install the fuse yet.
    5) Run a "remote" wire from the remote turn-on lead (usually blue or blue/white) of your dash mounted head unit to the amp turn-on terminal. Run a set of RCA cables from the preamp or subwoofer outputs on the head unit to the amp inputs.
    6) Run speaker wire, preferably at least 12-gauge, from the amp output terminals to your subs.
    7) Check all of your wiring. Make sure that no insulation was damaged or peeled off during the running process. Make sure there are no loose strands touching adjacent terminals or bare metal.
    8) Use a multimeter set to read "ohms" and test from the negative battery post to the amp ground terminal. You should read "0".
    9) Install the fuse.
    10) Turn on your head unit and listen to those big Kickers thump.
    11) Adjust the amp settings according to your manual.

    The best place I've found for in depth information on audio installs is The Install Doctor. You'll find step-by-step procedures, color photos, wiring details, and even the tools required. I recommend that you begin with the "tech docs" link and read through some of the PDF documents.

    Hope this helps.

    Amplifier cuts out when turning the gain up

    Make sure the amp is getting good power and ground - there should be 12V across the two terminals. Also make sure you're giving it the proper ohm oad - how do you have your subs wired up? Do your headlights or interior lights dim when this happens?
