How can I fix my amp?

Is my amp drawing too much power? How can I fix this?

  • I have a 1996 ford thunderbird 4.6l. My head unit is a sony cdx-gt320. Tonight I hooked up my subs and amp, the amp is an mtx 800 watt amp with dual voice coils or something like that, and I have 2 10's. Anyways, I hooked everything up, installed the fuse and all that good stuff. Well I turned the key to on without the car running and everything worked fine. When I started my car everything was going okay, I went to back out of my drive way and my subs turned off and everything dimmed for a second. They wouldn't turn back on after that and when I tried to accelerate my car almost died and the headlights pretty much turned off for a second. My battery is only a few months old. Is there any way I could maybe tune it differently, or something? Or is my alternator not strong enough? The car will barely drive. It was night by the way, so I had all my lights on. I'm running an 8 guage wire for the power, 8 guage for the ground, and I'm not sure about the amp turn on but it's pretty small. All I know about the fuse is the brand is Boss. Other than that, I don't know. Any input would be great, I'd really love to get this all working without spending too much more money. Thanks!

    please DON'T buy a capacitor. its a waste of money, instead do the big 3, go to youtube to see how its done also get a better battery, a stock battery is only for stock systems not big stuff the best battery you can get at a normal price is an optima yellow top. now if you want to go big you can get an XS Power battery. and yes that is the problem, the amps need more power than you are giving them

I don't think it has anything to do with your amplifiers power but it does sound like your alternator is going bad. You could buy a cap but it wouldn't be of much use to you. Rather you should upgrade your alt to a higher output model " since you need to replace it soon anyways "and think about buying a larger battery

I doubt that the amplifier is overloading the alternator to that extent (and you can always test it just by turning the audio system off, and see if the problems persist). My guess would be that you left the battery terminals or some other charging system connection loose after the installation. Another possibility is a blown fuse or fusible link between the battery and alternator.

Sounds like your amp is blown. I had a customer come to me not too long ago having similar issues. I trouble shot the system and couldn't find a real problem. Alternator tested fine. Battery tested fine. Wiring was a little unsatisfactory so I replaced a bunch of that. That didn't help. Check all his wiring and everything was wiring well enough. On a whim I swapped out his amp for a new amplifier and everything was fine after that. I'm not saying this is your problem for sure, but it very well could be. Don't rule it out.

you probably killed the battery having the doors open or listening to the music with the car not running

Buy a capacitor that goes in-between the amp and the battery. Walmart sells one for $70. Also check your battery size.
