Amp gets power but doesnt send anything through speaker wire
The bolt that hooks the ground wire into the battery is stripped it could be intermitting power to the amp but the amp is still getting power just not sending any and none of the fuses are blown should i try a new battery
Re: amp gets power but doesnt send anything through...
There are several things that could cause this that i know of, bad ground not being one of them. A bad ground terminal should cause a noticeable distortion in sound and cause the amplifier to turn on and off. If you are getting power and no sound, the first and easiest thing i would check is your RCA wires. Replace them with known good wires. If that does not work, are you positive the speakers you have hooked up to your amplifier are not blown? If available, use a DVOM to check resistances on the coils on your speakers. An open lead reading indicates a blown voice coil. Also make sure that your speakers are each hooked up to a positive and negative terminal, as some amplifiers have two positives next to each other and two negatives, while others go + - + -. Your amplifier could also have bad input or outputs, but i would try these other easy fixes before resorting to buying a replacement amplifier. The only other cause to my knowledge would be bad RCA outputs on your head unit. If possible try with a head unit you know the outputs work on.
Hopefully one of these suggestions solves your problem.

Most amps have 3 places where you need to hook up wires to power them. the 1st is a ground wire that at best is 1 foot long and it goes on the ground or negative 12 volt connection then a bolt on the car you may need to sand off the paint for it to work, 2 a RMT or remote wire that is normally in the middle of the power and the ground connections the remote turns the amp on and off so it needs to go to the remote wire on the radio or a ignition spot on the fuse box - turns on with key on and off when you turn the key off , 3 the power wire is hopefully large 4 gauge wire and goes to the + 12 volt plug on the amp this wire has a in line fuse and goes to the battery and to the amp only. RCA wires go from the radio to the amp and are round and just plug in with no screws some factory radios need a conversion kit you can get at walmart for RCA wires. the speaker wires have some sort of mark or line to tell you what to put were like if you put the line on a negative on the amp you need to put the line on the negative on the speaker box to or it will not bass and could hurt your amp. ask me if you need anything else :) and please rate :/
Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.
Generally if an amp goes straight into protection, the amp is not grounded well enough. Either you should find a new location to ground the amp to or unhook the power wire from the battery, remove the ground wire from the chassis of your vehicle. Strip the paint from the chassis, since it doesn't conduct electricity, and remove any corrosion or copper shielding from the ground connector. reground to a solid metal location Can be grounded to the brace behind the back seat or to the seat belt bolt for best results. An amp draws a lot of power, there it needs to be grounded well. Hook back up your power wire to the battery and see if your issue is resolved.
Are you using the correct fuse? if so,
more then likely, you don't have a good ground. Try grounding to something else that has more direct connection to your frame. If that doesnt work, try getting larger power cables.
I had the same problem with my 2500w xplodes all I had to do was get a thicker cable for the ground and battery connection. What was happening, was it was needing more power then the wire and fuse could handle, so it would blow the fuse, since the higher you have it, the more power it needs to feed the watts.
I would try grounding it directly to the frame on a good part of the frame before spending another $70 on new power cables though.
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections. Send back ri factory for best repairs.
A thumbs up would be greatly appreciated if this answer is helpful to you.
You can find the color codes for a 1999 Buick Regal here. There is no dedicated amp remote wire. Neither is there a power antenna wire.
You could use the 12V "switched lead (yellow) from the radio or any switched 12V lead directly from the vehicle fuse box. I'd wire it through a dash mounted toggle switch so as to be able to turn the amp on and off manually.
The Sony 2150GSX is a 2-channel amp with the speaker terminals on either side. You do not want to ground the subwoofer itself, only the ground terminal should be connected to bare metal on the vehicle chassis or body as close to the amp as possible. The ground wire does not need to be run to the negative battery terminal.
A ground on one of the speaker leads will probably cause the amp not to power up. A ground on a speaker wire usually activates the amps protection circuit, causing it to not operate until the fault is corrected.
plug two subs in to amp in most powerful channel then your speakers in the less powerfull take your positive from your battery and hook it to your amp your ground wire shud just touch a solid piece of metal take your remote wire and hook it to your deck all other wires shud be with your deck need n e thing else holla
first you need to run a power cable for the battery to where ever you are going to place the amp DO NOT hook the cable to the battery until the very last just wire it to the amp for now.next you will want to ground your amp hook the ground wire to the amp and the other end to a solid piece of metal in the car this is very important if you don't get good metal on metal contact you'll blow a fuse. If you can hide it well strip back a bit of carpeting and use sand paper to remove all paint from the metal and drill a hole for a screw. once that is finished you will need to run a remote wire from the amp to the car stereo usually these are the blue wire on the harness in the dash. once that is hooked up run the rca cables (reds and whites) plug in to amp and then in to back of cd player. once this is all hooked up and fully secure hook the power cable to the battery make good contact and if everything is grounded right you should get the lights on in the amp. Next step hook up the speakers run speaker wire from the amp to your speakers make sure negative goes to negative and positive to positive or you'll get clipping and it will sound like ****. that's pretty much the jist of it. if you have any questions let me know.
The only effective way to troubleshoot this is with a digital multimeter. Test for voltage on the power terminal and the remote terminal (using the ground terminal for your black probe). If you have voltage on both terminals, check the amp's built-in fuses; if they're good, then you must have a defective amp.
If you have voltage on the remote terminal, but none on the power terminal, check your fuse and fuse holder at the front. It's not unusual to have a blown or defective fuse that looks okay.
