My friend gave me an old Kicker 300.2 amp and I was wondering if I could just put two of my door speakers in each input on the amp and power them. I have aftermarket Kenwood speakers that are rated at 70 watts rms and wanted to power all four of them with this amp. Is it possible? I want to keep the amp at 4 ohms, I don't know if I can wire in series or something with door speakers to be at 4 ohms. Also, how do I go about connecting another power wire since I already have 0 gauge coming from my battery? Can I just use my old 4 gauge wiring and connect it on the battery, too? Then I'd have two power wires coming from my battery? I'd appreciate any input on this.
