needs amp integration harness or complete bypass.
when's the next time you'll be in va beach?

BTW, done this many times. Know exactly how to make it work...

I Cut The Harness Off The Amp To Try And Bypass It But ... No Sound.i Know All The Connections Are Right

basketthis

They can't be right if you have no sound. How do you know what wires you were supposed to connect to? Did you run all new speaker wire to the amp from the head unit?
Do you ever come to va beach, va?

basketthis

BTW, should never cut a harness off..... IMO. Just splice into it.

I Extended The Wires From The Amp To The Back Of The Head Unit. I Have A Wiring Diagram I Got From Work Off Of Alldata

There is two harnesses going into the factory amp. There is an input (from the factory unit) and an output (to all the speakers). It should be fairly easy to distinguish between the two. The input will have "thinner" wires in it and the output will have "thicker" wires in it. You need the one with "thicker" wires which is the output harness from the amp. Is this the one you used?

The 2 White Connectors One Is For The Rear Speaker And Subs And The Other Has The Front Speakers And The Power Wires. Do You Know What The Other 2 Connectors Above Do. One Is Orange And The Other Is Black. So I Have A Total Of 4 Connectors On The Stock Amp. The Wires That I Connected To Are Thick

Pics maybe?

Sometimes the wire colors that they give you in diagrams are not correct. Even if it's for your exact model car and it's from a reliable source, it will be wrong a lot of times in high end systems. It's best to test to find each individual speaker. Where did you find your factory amp? And, how did you know it was the amp?

perrychad

The Amp Is Behind The Glove Box. I Was Just Going Off Some Installs On Here.i Took The Door Panel Off The Pass. Door To See What Color The Wires Were. I Know I Have One Speaker Wired Up Right But Still No Sound

basketthis

And I am assuming that the factory radio was working.
Closeup pics would help alot. Or if you can come to VA BEACH.

perrychad

Yeah The Oem Radio Played Fine. I Was Reading In The Manual That It Says Not To Use With Speakers Between 1-3 Ohms. The Ones In The Door Are 2ohms. I Still Should Be Able To Here Some Sound Right? Or Do I Have To Change My Speakers For This To Work?

basketthis

You should still have sound if it's wired properly. An aftermarket radio should not be run on speakers with less than 4 ohms, that is correct. You can run speakers at a lower ohm load though without any problems. Eventually, it will cause problems and could cause the unit to overheat or malfunction, but sound will still come out of the speakers.... I currently have mine running off of an Eclipse headunit at lower than 4 ohms....
