my friend just installed an audiobahn a1801t amp (i know dont say it) on 2 type Rs. When the subs hit hard the amps voltage supply drops down to around 11 volts from 14. Is this normal or is something wrong?
no, a cap will make an enormous diffiernce, it will accualy take some of the stress off the alternator. a 60 amp alternator is still far too weak tho, i'd upgrade the alternator, but the cap is a must. a cap will hold you over till you can upgrade the alternator if you decide to upgrade, go with at least 100 amps.
also one more question since u are being so helpful. Im about to take my own stereo out of my car and put it in a Bronco and add 2 more type R 12s. Any idea where i can find the amps on the alternator of an 87 bronco?
(This is said in every single thread in the place, but I'll repeat it again anyway.) A capacitor actually is going to put more strain on your system if your charging system isn't up to par with what you're running. You'll deplete the cap, and the alternator will have to supply power for your system, PLUS recharging the cap. You'd be best off getting an HO alternator right off the bat. Plus upgrading the wiring to your alternator, battery, chassis. The "Big 3" wires as they are commonly referred to.
not to critisize your info jake, but where did you get your info from? adding a cap is like adding a fast charge/discarge component to the the battery it should add no stress, and help take stress of the car batt. for instance i have a 90 amp alternator, and my amplifiers draw 140 amps. the voltage meter on my cpacitor nevr drops below 12v while the car is running (at idle) and usaly satys around 13.5v w/o the cap my voltage often drops below 10. knock on wood 2 years later alternater is still going strong with no signs of stopping. any type of system will add stress to the entore charging system, the point of a cap it to stiffen the charging system.
A capacitor will NOT replace the need for a high output alternator. If your electrical system is inadequate the only way to fix it is to replace the alternator. When the battery is run down, and when the capacitor is depleted, the alternator has to work even harder in order to supply current to the car, the audio system, and also to recharge the capacitor as well as recharge the car's battery. By adding a capacitor to try taking the place of a high-output alternator, you are causing more work for your alternator, and causing even more damage to that stock alternator.
hahaha...joe and james is right...micheal....the cap will mess up his car and he will enevitably have to replace his alternator anyways...just replace that and be done with it...should be able to get one for about twice the price he would pay for a nice cap anyways....
