Car Forum / Driving, Maintenance, Tuning / Car Audio / August 2005PLEASE HELP! need advice.
i want to run 4 subs and 2 amps, so 2 subs to each amp. i have th correct capacitor, and a power distrobution block and a groun distrobution block. I have tried over and over again to wire this setu but have failed so far. if someone could give me a diagram or detaile instructions on how to do this i would definitly appreciate it. Than you. if it helps at all heres more info 12' 3 jbl gt120 1000watt peak 12' 1 pioneer 600watt peak all single coil 4 ohm jbl grand touring 300watt amp bridged spl 820 watt amp bridged 1.2 farad capacito -- joeyboscarin CarAudioForum.com - Usenet Gateway w/over one million posts online ok ok ok let me just start with asking how much you understand about wiring the subs? You have 3 4 ohm subs running of an amp that won't run mono less than 4ohms i'm quite sure. If it was me i'd run two jbl's off the jbl amp (i'm assuming this is the mono amp but you didn't list a model number, that would help a LOT). parallel the wiring on the subs and you'll get about 300W for two subs. Take the other two subs and run them stereo off the SPL amp but honestly i think this is too many subs, too mixed and not matched well with the amps. If it was me i'd consider selling some stuff and finding something better paired, 4 12s is kinda excessive, but thats just my opinion > i want to run 4 subs and 2 amps, so 2 subs to each amp. i have the > correct capacitor, and a power distrobution block and a ground [quoted text clipped - 10 lines] > spl 820 watt amp bridged > 1.2 farad capacitor everything you said is correct. however i have the wiring to the sub from the amp down. i just dont have the capacitor to the amps wiring all my fuses are working btw -- joeyboscarin CarAudioForum.com - Usenet Gateway w/over one million posts online I'm not completely sure you'd need a capacitor at all, what kind of car do you have or if you know the amperage of your alt that would be better. I'd run my power wire to a distro block then to the amps, the same for the ground (unless you want to run them seperate, that will work fine also). I don't think you'll be drawing too much amperage at all for now so try it out first, hooking the cap up later shouldn't be a problem. You never really mentioned what the actual problem you're having is.... > everything you said is correct. however i have the wiring to the subs > from the amp down. i just dont have the capacitor to the amps wiring. > all my fuses are working btw. the car is a toyota corolla. small car im just doing this project caus i figured it would be a good setup for awhile till i get another car. the problem im having is that im wiring everything up as to everyon around me's suggestions but both the amps still wont come on. also th cap wont stay charged. this has me thinking its wired wrong. ill tr it without the cap i just thought it was way too much but if you say s im sure i can get it to work. thanks for your help -- joeyboscarin CarAudioForum.com - Usenet Gateway w/over one million posts online i'm running a 1200d orion (class d helps) and a crappy pionner that puts out like 35w/channel (2 channel) and i only have a 90amp alt, things do fine until i really boom and then i get dimming lights, but my head shakes so much its hard to notice :-D > the car is a toyota corolla. small car im just doing this project cause > i figured it would be a good setup for awhile till i get another car.

Seems to me, some people think they are supossed to be wired "inline" by this I mean: Battery + to cap + cap - to amp + That might be your problem. Most capacitors that I know are: Battery + to cap + cap + to amp + cap - to ground > the car is a toyota corolla. small car im just doing this project cause > i figured it would be a good setup for awhile till i get another car.
