Excellent Amp. I had a Power Acoustik A2400db on one 12 @ 1 ohm and it sounded good but my headlights would dim. After installing my Sundown on the same 12 @ 1ohm, I noticed it was a bit more louder but my headlights didn't dim at all! The amp, IMO looks good and puts out good power with less current draw. I haven't tested my voltage drop but I will when I get a chance. Definitly a good choice because of the quality but if you want more power, you could get another one and strap it. I highly recommend this amp.
