hi. i am looking to buy the AudioPipe AP15001D amp. but i googled it and am seeing that people are saying you might need an electrical upgrade?not my budget is really tight and i cannot afford to get this amp if i have to upgrade the electrical system or get a new battery. the amp goes at 1500 rms at 1 ohm. and my that i got are pioneer 3002 d2 which goes at 3500 rms maxx. the amp wiring i ordered is a audiopipe 4 guage 2100k wire. my decision to get an amp lies on this!thanks for the help!
