Sounds like the amp is blown. Is it the fuse at the amp that blows? or the one at your battery? disconnect the ground and power wires from the amp and check for continuity between the ground and power on the amp terminals. you should have no continuity, and if you do i would check for a shorted power supply mosfet. try disconnecting all speaker wires, rca's, and remote power and see if it still blows. If it does its a problem in the amp, probably blown mosfets.

I recently installed 4 speakers, a deck, an amp, and subs into my truck. About 8 hours after I installed them the speakers suddenly went down, the subs kept thumping, but the speakers are down.

The speaker wire connected to the amplifier if you used one could have come lose or in the back of the cd deck could have come lose. Just check those basics first to make sure everything is strongly connected and make sure you have the correct gauge wire because if you have something rated to high or too low it might not create a solid link

I just put a touch screen deck into my 1995 6.5 2500 gmc and an amp and sub and then my dash lights keep blowing fuses and now it just wont do anything anymore

There is a wire that comes from the dash lights and lights up the radio at night. You probably hooked that wire up wrong, causing the fuse to keep blowing and now maybe the dash lights are toast from repeatedly being shorted.

You have to be more specific. Subs thump, that is their purpose. You need to be more in depth about the sound, because it sounds like the subs are doing their job by thumping out bass

The light comes on but little sound comes out

theres a chance you may have blown up the amp. never put a sub that is to strong for the amp because its pushing all of the energy out of the amp to power up the sub, causing the amp to blow a fuse or the channels, on the back there is control of frequency turn everything all the way up to see if you can even get it to thump hard but dont blow your sub if it pops turn down some stuff and check the head unit to where its fading to the front or rear and balance to left or right

Thumping sound

You either have a bad ground from your amp to the vehicle or a problem with the amp. Where is the amp grounded? Do not ground an amp to a seat bolt or side panel on any vehicle. The weld points on the car itself cause issue with ground. Take the ground wire directly thru the bottom panel (floor) Check befor you drill! don't hit a wire/fuel line, etc. That will give you a solid ground. Keep your ground wire length to a minimum. 18" or less, and use the same gauge wire for ground as you do for power. Hope this helps

Thunping coming from subs when car is turned off.

2 things to try, one. run your RCAs on the opposite side of the car as the positive wire. if you still hear the thumping try changing your RCAs. if you still hear the thumping, try a different anp or head unit. if you still hear the thumping, your subs are blown. best of luck

It wont hold fuse blow evertime

if the fuses are blowing as soon as it comes on the amp is bad, if the amp is actually playing but popping the fuses after a lil bit of playing make sure your subs are wired to the proper impedence for the amplifier if the amp is pulling too much current due to the subs being wired at too low of a ohm rating for the amp.

Hi again,

My apologies, missed the connection. Now I remember, must be really getting old.

Back to your concern, which fuse pls? the 15 amps for the Panasonic or the amp"s fuse.

Incidentally, even if the speaker wires were wired incorrectly, that would not cause the fuse to blow. The only way the fuse would blow is if the unit was connected with the polarity reversed, even just once. Internally, most units have a reverse protection diode and/or regulator that would short circuit itself. Thereafter even if it were wired correctly to the battery, the fuse will always blow.

Looking forward to hearing from you.
