No. I would say 4 gauge minimum, if it is in your trunk I would say right around 1 gauge

well the guy i bought the car from already put the 8 gauge in for his old system, he kept the wiring in. i am pretty sure i wont have enough room in my trunk for a 15" especially with the big box im going to need. so i am going to take out my rear seats, put in a box where the seat was and just put the sub through that....

also, what is the minimum amp alternator i am going to need? right now i have the stock 75 amp 14.7 volt.

No you won't need a new alt. Its rms is only 650.

4 ga would definitely be the best for a BX1500D

i dont know much about car audio, as if you couldnt tell already

but i have 3 wires in my trunk, one is red (8 gauge) one is dark green (8 gauge) and a light blue one (not sure the gauge but the wire is really thin. and then i have the red and white that hook up into the amp? my question is what is the thin blue one for?
