Default Alpine to JL Audio- Subwoofer

This is the second stage in the conversion of the stock Alpine speakers in my 2011 Ram CC Sport to JL Audio.

The subwoofer used to replace the stock Alpine 8" subwoofer is the JL Audio SB-D-QDRAM/10w3v3. For more details, go here:

The amplifier used is the JL Audio XD 600/1. For more details, go here:

Also, the JL Audio harness XD-CLRAIC2-SW was used to connect to the stock sub harness providing an RCA signal to the amplifier. This harness is detailed here:

As for amplifier wiring, the JL Audio XD-PCS4-1B was utilized. It can be researched here:

Last but not least, a level controller, JL Audio HD-RLC was utilized. It can be found here:

Now that all of that is out of the way, let's get to the good stuff!

I did not follow the JL Audio instructions which asks you to drill through the floor and bolt the sub box down. Instead, I fashioned a black bracket similar to the stock sub enclosure and bolted the JL box down in the exact same location.

The wiring was uneventful as the plastic block off plate beside the brake master cylinder made for an extremely easy location to run the line. I hate to see audio wiring in the engine bay, or anywhere for that matter, so everything was loomed identical to stock and hidden.

The amplifier was mounted on the non-sub side of the cargo area. All wiring was run under the carpet and amp and then connected. The HD-RLC was mounted under the steering wheel and to the left. Easy to get to and adjust and not highly visible.

Amplifier Settings: 24db Crossover/50hz/No input sensitivity adjustment.

Results: Wow! Absolutely breathtaking bass response and finally, the entire system rocks! This sub setup can play everything from Rap to Orchestra and sound like it's perfectly suited to all formats. I couldn't be happier!
