Gonna hook up my amp and subs in my dads car- an 89' Toyota Cressida. I'm testing a used amp i bought that just aririved.
-Coustic 801DB (older, powerful model) will be running @ 4 ohms = 400RMS.
-Into two Audiobahn AW1251Ts.
-It's a class D amp, also.
-Wondering if i'll encounter any problems, better to be safe than sorry, i dont want to blow my dads battery or hurt anything. I reckon the car has a decent ALT also.
Soon as i get reassurance, i'm gonna go ahead and start wiring.
Thanks in advance! CLAP

If you don't know the ALT capacity on that car, can always call someone like AutoZone or Pep Boys for the stock ALT specs. Then you will know what to do next. My guess, it will be somewhere between 75-90A peak output.
Can also fuse the main power line a bit on the low side to keep the amp from pulling too much current. (25-30A fuse) That will protect the BAT/ALT from any damage due to large current pull from that amp. If the fuse blows, the amp will shut off, but prevent heavy current draw by that amp.
FYI: 400 RMS/13.5 = ~30A of current draw. A #8 wire is adequate for that level of power as well. It will take (#8) 40A with ease and rated up to 50A if short wiring is used.
Hope that helps Grasshoppa,

Yes, Master. CLAP Helped indeed, just going to be wiring them up tonight at the house, then back over to my apartment.
Thanks for the info, i'll be using 4 guage, so, no worries.
Can't wait to hear em!
