S.I.K: FS1000 2014-2019 GM | GMC Crew Cab

If you purchased the speaker Component Set from us please let us know in the comments below so we wire in the crossovers on the rack for you. Otherwise a 2 foot lead of signal will be left from the amp that will go into the crossover and the speaker wires that go to the crossover output. Diagram in our F.A.Q Section.
The amplifier options below will serve as the signal processor from the Elite Loopback Harness, The loopback will also output back to the factory speaker locations via the factory wires through the harness. AudioControl amplifiers provide GTO, chime control, 40v input and SUB OUTPUT with Accubass so adding a sub amp is one RCA cable away. The DSP (D) amplifiers offer advanced tuning options, line frequency selection and built in O-Scope so you can see the signal you are working on along with all the options above like chime control, Acubass etc..
Need some bass? Some music just doesn't have great bass or bass at all and it makes a difference. If you listen to Rock, Banda or like oldies. Adding a bass recreation unit is a must! We offer the only bass recreation units on the market worth investing in. Units will require tuning. (Videos Below)
The Amplifiers below are all compatible with any of the choice combinations above. When purchasing a mono amp make sure that the final OHM load match between all the subwoofers and the amps capability. The RMS of the amp can be higher than the total RMS of the subs. This will be tuned to the proper output regardless; based on the impedance, sub specs and vehicle voltage.
Selection will add to the price

Unique

Our designs are not just original they are both cost effective and durable.

Original

We work very hard to be original and design products that look nice but are affordable. Unfortunately some have taken advantage of our designs to over charge.

Because we know you wont need it

But just in case you do its there.
