Overview
So Much Performance in an Easy-to-Bolt-in Package
This combo gets you both the spectacular-sounding Infinity Kappa Perfect 900X speakers as well as an Arc Audio KS125.2 BX2 amplifier. The KS125.2 amplifier has a built-in BX2 bass boost feature that is perfect for Harley sound systems. The BX2 feature uses harmonic bass tone manipulation to get a lot more bass out of your speakers than otherwise would be possible. And to make the BX2 feature even better it creates more bass without extra demand on the speaker or the amplifier.
Product Description
Amplifier Signal Inputs
Perfect for upgrading to a 4 speaker system fro a 2 speaker system. The Infinity Kappa Perfect speakers are loud and spectacular sounding right out of the box without any special tuning required.
The Arc Audio Ks125.2 has both RCA line level inputs as well as high level inputs. If feeding signal direct from the factory radio without a DSP, you will need to hardwire the included high level input harness to the factory radio speaker outputs. We can do this for you upon request. Please call for more details 1(888)311-0016.
