2021 Lance 825

I wanted a touch screen, CD/DVD player, better sound, and Sirius XM.

Camper Stereo Upgrade Factory Jensen

After removing the Jensen, I organized the wires. They were labeled, but I double-checked them and added my own labels.

Camper Stereo Upgrade OEM Wiring

My OEM Jensen had zone A (dinette), B (cabover), and C (outside). Last year, I removed the zone C speakers. This left four speakers which worked well with this Pioneer.

Camper Stereo Upgrade New Pioneer Project

I used WAGO 221-412 Lever-Nuts to test the unit and speakers before butt connecting the Pioneer harness to the Lance. My Lance speaker wires were 14 AWG and my new Rockford Fosgate speakers required POS (0.187″) and NEG (0.110″) female spade quick connects.

Camper Stereo Testing The Wires

Camper Stereo Upgrade Cutout

Camper Stereo Upgrade New Harness

I traced the new cage and cut the wood to fit. I used a file to fine-tune it for a tight fit. I ordered a custom matte black frame versus making my own.

Camper Stereo Upgrade Pioneer Cage And Frame

My son reinforced the wall and floor to support the cage.

The unit pulls some amps when powered off, so I added an on/off switch. I also added a wall-mount USB for AUX input.

Camper Stereo Upgrade Pioneer Rear

My receiver plays DVDs, so I installed a Microbypass to trick the unit into thinking the parking brake is on so I can watch DVDs.

Depthwise the Lance speaker cutout is less than 1-inch. Most speakers are 2-inches or more in-depth. I found 1-inch spacers on eBay and shallow Rockford Fosgates which fit the 1-inch spacers and original screw holes perfectly.

Camper Stereo Upgrade Dynamat

I lined the speaker holes with Dynamat. I used black Testors model paint to cover all visible screws.

RV Stereo Upgrade Speakers

In the pro column, the Pioneer has a beautiful touchscreen, a built-in DVD player, Bluetooth and USB input, SIRIUS XM tuner and, together with the new speakers, much better sound. In the con column, I lost Zone C (outside), but I could use a Bluetooth speaker or open the windows. I also lost the Jensen DVD output to the cabover television, but I can play DVDs on the Pioneer. Overall, I love the new stereo system.
