These adaptors allow you to install an aftermarket amplifier to your factory head unit. These devices take the speaker level outputs from the head unit and reduce the signal to a level of which an aftermarket amplifier can use without overloading its inputs.

BASSFREQ 2 Channel line output converter with bass enhancement


You have just added a subwoofer to your system but something just isn’t quite right. Maybe what is needed is a little bit of equalization? It could be that the crossover built into your amplifier doesn’t have a steep enough slope. Maybe you are using a ported enclosure and could really use a subsonic filter? Whatever the issue is, the bassFREQ can help resolve it.

The bassFREQ has RCA inputs but also includes the same class leading LOC as our link series products, so integrating with an OEM system is a snap. There is Parametric Equalization and a 24dB/ octave low pass crossover. A Remote Level Control (RLC) is included.
