Hey everyone,
I'm new here on the forums, and just wanted to share my experience with having my new system installed this week. I have a few questions about the issues im having as a result of the poor quality work and lack of attention to common sense practices that the shop i used applied to my truck. anyway, to start off, i have a 2006 Ford Expedition XLT. Before this install i had the completely stock ford 4-speaker (no sub) stereo. Heres basically what went down at the shop.
Things i provided:
1) Alpine PDX 4.150 4 channel amp (for doors)
2) Kenwood Excelon 9960 Nav/HU
Things i bought from the shop/included in install, and things discussed to be done:
1) JL 13w3v3 Sub (they gave me the 8ohm model, i assumed they were giving me the 4ohm since thats what the amp they sold me is rated for)
2) Alpine PDX-M6 mono amp (for sub)
3) dynamat all doors/under sub enclosure
4) 1 pair Focal KRX2 Power components for front, 1 pair JL C2 coaxials for rear
5) running power to amps and installing head unit
6) wiring speakers, straight new runs from amp to speakers
7) removed half of 60/40 split third row seat and installed wood sub/amp box in floor
8) install door amp under driver seat
9) tune system
So here is what they did after having the car a full 7 days :
For power: they ran 4AWG from battery hot to inside dash in car, split to 4AWG to each amp. they used the same 4AWG from the amps to chassis ground. they did NOT upgrade the chassis ground wire from the battery, which from the factory is still 10AWG. inline with the 4AWG from the battery to amps, they installed a 250A wafer fuse in a fuse holder which they installed right under the hinge of my hood, which now does not close fully. also by installing the base of the fuse holder where they did, the lifted the left side of the bezel that seals the engine compartment from the hood to keep out water, breaking the seal.
Speakers: they used 12AWG speaker wire from amp to sub, but for door speakers, they ran the same 12AWG from the 4 channel amp to the crossovers (which they didnt mount, but threw behind my headlight switch just flopping around by the wires). from the crossovers in the dash, they went 12AWG to the tweeters directly, and then 12 AWG from the crossovers to the stock speaker wires from the factory harness, connecting them to the factory speaker wires with a drop of solder and a few twists of tape, using the stock wires in the doors for the woofers from the KRX2 Focal set.
Lastly, for some reason, i have a nasty engine noise coming out of only ONE speaker (the pass rear door), the rest are clean. when i went to check the connections on the amp, i couldnt because they mounted the amp too far foward and then jammed the seat back in, crushing most of the wires on the connection side of the amp with the front rail of the seat. i have a feeling this has something to do with my engine noise, but havent had time to diagnose yet.
anyway they charged me about $5000 including labor and all the equip/parts that they provided. i feel like i got taken for a ride.. i see multiple issues with this but just want to make sure im not crazy before i go back there... any input is appreciated, thanks
