First round we did a Digital Media Deck with backup camera and new JL Components up front and coaxials in the rear.
The sound was....MEH.....and the deck was a pretty horrid attempt at a digital media player...but it worked....for a bit.
Round 2, customer wanted better sound, and fully amplified was the only way to go.
We nuked the deck and went with a basic deck that gave him front access to the USB and Aux inputs. This did away with the backup camera screen, so we added and over-head screen to see when in reverse.
We amplified the already good speakers with a Kenwood 4 channel amp and pumped up the bass with a JL Audio 500 watt mono amp powering a ported 8" JL woofer.
All in all, the customer was happy, the highs were high and the lows were low.....a good install on labor day weekend!
