thanks for all the suggestions guys. sorry i didn't make things clearer. here's the details... my vehicle has a small alternator i think about 80 amps, replacing the alternator with a higher amperage one is not an option as it is too costly and for my application, probably won't be needed. i'm replacing the battery already, since the one right now is pretty much shot. the only amp i'm putting in will be a 5 ch. that has (3) 25 amp fuses and is rated max at 800w, that's why i only asked about a 1 farad (no need to go bigger). i was only asking about the cap option just in case i needed one, although i'm pretty sure i won't need it. i might still get one if i can find a 1 farad in stock somewhere, it should be cheap since hardly anyone uses the smaller ones like that (as long as it's low cost though). i won't be driving around at full volume at all either. if anyone has any other ideas or feels i'm going the wrong route, just lmk what you think. the last caps i ran were about 10+ years ago, i think were streetwires. the current ones are way too much overkill for what i'm doing this time so, i won't be needing those for this low end of a system though. so i just need names of decent quality ones at the lower price range, since i'm unfamiliar with alot of the newer brands. thanks again.
