System's Current

[allenjanthony 10+ year member]

I currently own a 93 Acura Legend. I installed a Precision Power PCX 480 amp in my car and lately my windows act like they do now want to role up. I was wondering if I needed to install a new alternator or do I need a cap for my amp. I took the amp out and it rolled up fine like nothing was wrong. I would appreciate all help if possible.

Thanks

Do you have a #4 gauge wire to a fuse distribution block and from the block a #8 gauge wire? If so add another battery in the trunk. From the fuse block get a #4 wire to the positive of the battery and the negative to the chassis this will help a lot if you have enough money left have an electromechanic put a GM 120 amp alternator that will fit Honda base and a capasitor is good to have if the amplifier is for the sub-woofer.

Right now I only have one amp hooked up and I am having this problem. I already have a 4 gauge positive wire and a 4 gauge negative wire hooked up. I don't have a battery in the trunk. Between the time when I disconnected my old amp and hooked up my new amp, I had no problem with the windows rolling. As soon as I hooked an amp back up I started to have problems with the windows rolling up slowly. My lights don't dim so I have no idea of what it could be.

Not all Amps are created equal some of them use more current than others specialy older amps.

the best bet would be to either upgrade to a higher amp alternator or get your current one rewound to a higher amp rating....and i wouldnt recomend getting a cap untill you have done one of the prev. because getting a cap will put more of a strain on your already straining alternator....as for a second batt...if u go w/ one you'll either need to wire in in paralell w/ your current one which would put an even greater strain on the alt. or just wire somthing directly to it and make sure you have a batt. charger on hand cause you'll need to recharge it every so often....so your best bet would just upgrade your alt or rewind it....good luck
