    New headunit. Lower volume/sound quality

    I replaced the stock head unit with a Kenwood Excelon DDX6904S. $1,000 head unit...

    The new head unit is about half the volume and half the sound quality of the stock head unit. At 75% volume the heat and road noise drown out the stereo.
    I've installed at least a couple dozen head units before and never had any issues of lower volume and worse quality.

    The new head unit says 4-8 ohms, my trucks speakers (stock) are all 4ohms.
    Iíve double checked all my wires, nothing is out of phase, or connected poorly.

    Iím seriously about to return this headunit and go install my old $65 pioneer headunit from my work truck. At least that HU didnít botch my system.

    Any suggestions/explanations?

    My vehicle is a 2011 Chevy Silverado 1500 LT, crew cab, no Bose, no dash speaker, no factory amp (99% sure about the amp), tweeters on the front columns, 6.5s in the 4 doors.

    could be that the unit you got was mainly intended to be a dead head and therefore has a weaker internal amp. Those lower end units have decent internal amps as theyre not usually run with an amp hence their 2 volt pre outs

    also, its not a $1000 deck, its available for $550 on amazon



    2002 Honda Accord sedan V6 (automatic slushbox)
    2 Rockford p3 12s (dual 2 ohm)
    Pioneer AVH-X4500bt (takes about a year to start playing music on the USB input)
    PPI PC275 running 1 sub atm, waiting to put the SQ 2200.1 back in and add the PhoenixGold Elite.4 once my electrical is up to snuff
    Stock front and rears (theyre actually squirrels listening to headphones that ive trained to sing what theyre hearing)

    I just added 5 SoundQubed stickers, and despite having no equipment upgrades, it added 76 DB!!!

    It's got 22 watts x4 so you should be good on watts. I've got the ddx6702s and never had any volume issues.
