How do you hook up a amp with a factory radio.. a 2002 impala


1- you need to provide a fused power wire from battery to amp
2- provide a ground wire from amp to car body or frame (be sure to clean off paint if connected to body)
3- connect your remote wire to your fuse box (16 to 22 gauge wire will be fine)
4- connect a line output converter which will allow you to use rca jacks (one side connects to the speaker wire in your car and the other to your rca jacks)
5- finish by connecting your speaker wires and rca jacks
if helpful please rate 4 thumbs up.

My 2002 impala chugs when accerating & idling.


I have a 2002 Impala with 3.8L.
I had a similar problem with mine. As I recall, mine would idle OK, but would chug and buck like crazy on acceleration. Note: I had NO check engine light!
I tried a new coil pack. No help.
Then I swapped the MAF sensor and that took care of it.
You can try to clean it first. It's located between the throttle body and the air filter.
They sell spray MAF cleaner at the parts store.
As I recall you will need a special torx socket to remove the sensor.

An ABS wheel sensor could be bad, you need to hookup a scanner to it to find the specific problem.

2002 Impala idles very rough


it could be as easy as replacing plugs and wires..but first check every single small diameter vacuum line you have as these get old the crack and get brittle i had a rough idle once and found a cracked vacuum line leading to my MAP sensor. i just cut off the worn end and just shoved it back on and it fixed it. Also its not very likely, but you do mention something about fuel gauge... so if you"ve never replace your fuel filter i'd spend the tim if to replace that as well. if its the new style with plastic clips, you just take a pair of pliers and squeeze and pull to release..but release pressure on gas cap before trying to replace the filter. can i get a very helpful thanks.

03 impala there is a factory installed amp all speakers. i am trying to find out if i can power another amp 760w pioneer form the amp that is already there? i have already put outputs for my RCA wires. can...


You might not want to do that. The 760W Pioneer amp might require larger wire due to the power consumption of the amp. Most amplifiers require a direct wire from the battery to the amp. The power wire for the factory amp might not require very large wire and if you tie into the power for that amp the fuse could blow and wiring in your car could melt or catch fire, The best installation is to run the recommended guage wire from the battery directly to the amp with a properly rated in-line fuse.

2002 Chevy Impala Radio Doesn't Work


Check the radio fuse? Box is drivers side end of dash(drivers door open)or pass side end of dash(passenger door open)
police models have a connection for the speakers (passenger floorboard under floor mat) to connect the speakers to the police radios.
If they had the speakers connected to their radios,they may have unhooked them and not connected them back to the radio.
The wires are brown,grey,blue and light blue.All into a blue connector.

Install two 10" subwoofers in a 2002 grand am monsoon.


The only way to Correctly do this is to Run an External Amp for your Subs. If you continuously run the Subs off of the Factory Amp It will Ruin the Subs and the Amp Eventually. This way you can still Connect the Rear speakers as they need to be. Please Rate my solution, I need all the Help that I can Get! Thanks!
