The E46 HiFi/HK harness helps replace the 10ch OEM amp completely with aftermarket balanced-inputs amps.
The E46 HiFi/HK harness includes all 10ch outputs of the OEM amp; the particular production date of your E46 will determine if all 10ch are actually wired in your car:
– front woofers
– front midrange
– front tweeter
– rear tweeter
– rear woofer
Please note that once the OEM amp is replaced then all crossovers are also removed from the OEM system. Each speaker requires a crossover.
No HK OEM subs wiring is provided by the E46 harness: OEM subs are powered by their own, separate OEM amp.
Warranty of harness is one year from purchase date. Harness is designed for experienced DIYers. Professional install suggested. Support limited to harness install; no support given to aftermarket parts not sold with harness kit.
