will this power my audio system? i have 2 12" subs and and a 700 watt amplifier, is this alternator powerful enough to keep my set up from killing my car?


  • The 130 Amp PA Performance Alternator should work with your set-up, however, if your subwoofers are rated rather high, and you use the full potential of your sound system often, I would highly recommend a higher powered alternator and/or a capacitor for your sound system.

PA Performance Premium Power Wire Kit needed? I have an 04 Mustang with a 3.9 liter V6. Do I need to install the PA Performance Premium Power Wire Kit if I buy this alternator? I was told I don't need a higher amp alternator but I'm on my third O'Reilly's lifetime warranty alternator in less than three years. I'm sick of replacing them even though they don't cost me any money. I'm always worrying if I am going to break down again and I still see my headlights dim when I let off the accelerator. I don't have a high-powered stereo but I am running 55w fog lamps all the time during night driving so I think I need this.


  • I would definitely install the wire kit. You should not be going through so many alternators, and your lights should not be dim. It sounds like you have a wiring problem and this kit may solve it. Also check your battery. Is it a large enough amperage rating for your application? Is it new and in good condition? Are the cables frayed, touching, clean? A bad battery will ruin an alternator. Check your connections and check your engine and chassis grounds. Parts store alternators are rebuilds on used cores so you never really know what you are getting. I'm sorry you can't enjoy your Mustang, It's no fun if you can't rely on it.

Do I have to upgrade my wires when purchasing this or is it plug and play in replacement?

Overdrive pulleys and a sub woofer? Would this alternator be able to run a sub woofer and overdrive pulleys without draining my battery? I have a brand new battery and a jl Audio sub woofer with a 2 channel 1000 watt amp.

    Great Replacement Alternator

    I've had to put several rebuilt alternators in my mustang over the previous years and time after time, they [three] alternators failed. After revewing new alternators at my local Autozone, I decided that this alternator produce more amperage and would be more sufficient to power my vehicle with all of its audio accessories. Now my car powers up quickly without hesitation and allows me to crank my tunes up with the headlights brightening my path. I am very happy with this product as well as the warranty that it provides.

    It allows for more power to accessory devices but I still notice a drain when my 2 12" MSubs with hammer memphis amp hit. The subs seem to hit with a more firm beat. My battery has not failed me since new alt installed I think due to increase power for charging.

    Great Upgrade

    My V6 Mustang has 42% underdrive pulleys installed and I have always had issues with the alternator charging the battery at idle (even without any of the accessories turned on). Finally, the alternator completely quit on me, so I decided to pay a little extra for this 130 amp alternator instead of the 105 amp alternators I was finding at the local auto parts stores. This alternator was well worth the money. At idle with my radio, headlights, and fog lights on, as well as the AC running full blast, the alternator is still providing enough power to charge the battery.

    Just do it! Thank me later.

    Was having a lot of trouble with the original alternator. So glad I changed it and what a big improvement over the stock 105 amp. This has the power you need to run all your electrical. No hesitation or dimming lights. I can have everything operating and the car still starts. Amazing upgrade and I just made my Mustang that much better. Easy to replace.

    Gets the job done but..

    I bought this alternator to replace my stock one because I have a aftermarket sound system and the stock alternator was failing. I took it to my mechanic and he pointed it out that the "connector" (the red plug looking thing) came damaged and he quickly thought on his feet and used my stocks connector and he put it on the PA Performance Alternator. I would have given it 4 stars since I have no issues but this product came damaged.

    Fixes More Than You Think

    20-30 minute install, on my vehicle (with upgraded intake, coil, plugs and wires)after adding this one piece, noticeable increase in gas mileage of 3mpg, better and smoother acceleration/braking response faster-harder/vert top up down/radio system louder/ windows faster/ all lights are brighter from interior to exterior/ transmission is more even and smoother idle / Overall, product works great, it seems increasing the electric input into the system has a broad sympathetic effect vehicle wide.

    Due to the car being 14 years old, the car had a little noise from the alternator. Runs smoother than it ever has, doesn't make any of the previous whining noises. Great buy in my opinion.

    Fastest Install, Great Power

    My stock was short on power after 116k, until i installed this new PA alternator. 3 sockets, 1 ratchet, and 1 wrench for cables. Curious to see how fast this can be done, i set my tools needed close by started my clock and went to work. 8 minutes to install and closed hood. Although, there is now a small winding noise, but figured it will go away once it gets some miles. Very impressed with the power gains for my audio due to increased Amps over the stock

    PAPerformance Alternator - 130 Amp (01-04 V6)

    After almost ten years, it was time to change my stock amp. Installed this myself, very straightforward instructions. Just check to make sure the battery is full charged after install. I have two 10'' pioneer subs with a 900 Watt amp. With the new amp installed, it seems as if the subs are more responsive and "hit" harder than before, and the overall engine has a little more "pep in its step". I did not buy the wiring harness since the increase in power is only 15 and I have not had any problems with the amp or the battery (battery is about three years old) since I installed this amp four months ago.

    Perfect fit

    Install took about 15-20 minutes. Alternator fit perfectly. Measured voltage with everything on, including the stereo which has about 800 watts. Voltage stayed constant at 14.4V. We did not upgrade the wiring harness. I would say if you chose an alternator with higher amps , the upgraded wiring harness is a must. Great product , Thanks AM

    Great Product!!

    This alternator is exceptional. My old alternator just was not up to the task of powering up my car the way it should be. I have an alarm,sound system and other high current items installed in my 04 Mustang and have had two alternators short on me in the past. As soon as I installed the PA Performance Alternator,it was game over. I started up my car quick and efficient,no more lights dimming just putting down the windows or anything extra. I only installed this alternator a few days ago but I already love it.

    New 130 amp Alternator

    This winter my little lady's battery decided to go out. It also caused the alternator to go too. So, after a lot of research (as much as I could process in 6 hours) I went with this product. Since I have an aftermarket sound system installed, I didn't want to run the risk of underpowering anything. Installed this next to a brand new battery in about 45 minutes (cold metal and bare hands don't mix very well) No more dimming headlamps or dash, and no more sound system shut downs while idling with the heater on. Good enough for me. I love that AM offers brand new alternators unlike most other product lineups elsewhere!
