    I’m putting in a jvc Kd x350 BTS In a 95 SHO I’ve heard if you have an enternal amp that you have to by pass stock amp. What do you consider and internal amp This is just an $89 head unit and I don’t think it puts out more than 14 watts a channel I also want to put in a soundsrream preamp equalizers has anybody tried this before I’ve got tooth correct wiring harness for the head unit Thanks for any help

    You will have to bypass the amps if you want to do it correctly to avoid problems down the line. The easy way to do this is get a premium sound bypass harness for Fords on top of the generic radio harness you already have. I'll see if I can look up some part numbers for you if they still exist. Last time i did this was ages ago. The harder option is to splice/rewire the existing harness to incorporate the low level RCA outputs from the head unit to the stock amps.

    Have you hooked this harness up it looks more complex then the regular non bypass harness. Thanks. I guess there’s more connections behind the radio thanks

    Sorry about the late reply but yeah I've used that harness before but it was a different brand on one of my previous cars. You run the bypass harness like you'd be setting up aftermarket amps/subs. The second harness is really long and you pull up the sills to run it along the side of the car under the carpet into the trunk. You then disconnect the harnesses leading to the factory amps and just plug them into the bypass harness. It's super simple. I ran mine along the passenger side then under the back seat. What it basically does is use the factory connections to run the speaker level outputs from the new head unit to the back where it would normally go to the amps and instead goes around them and connects straight to the speakers using the factory plugs from those amps to send them back up front. It jumps the input side of the amps and plugs them straight into the output plugs. You can sort of accomplish the same thing by making your own wires if you can run them the same way and crimp or splice them to the unplugged connectors.

    If your equalizer can somehow convert speaker outputs from the head into line outputs, you can use splice connectors on those to the harness that runs to the amps in order to use the factory setup. I wouldn't recommend using factory amps with a modern head unit because you will eventually get distortion issues after a while, especially at louder volumes.

    If going a DIY route I'd highly suggest getting wiring diagrams so you have at least an idea of where to start.
