Because some component in the amp is failing/failed and drawing too much current. The amp needs a repair shop. Poking around without knowing what you're doing can expose you to leather voltage. Don't do it.
Sounds like a grounding issue. Check all groundings from the amp and make sure the ground and a hot wire is not touching. If not, it is probable a bad amp or your reduction in ohm rating is probably too low for the speakers. Amp to speaker ratio.
All amps are basicly the same. It should be plain as day where the speakers connect to. The 12V screw connects to the main power from battery, be sure to fuse that wire and use a proper size wire, thicker is better,I suggest at least 8gauge with 40amp fuse. The GND is ground and should connect to car metal, file paint for soild connection. The REM is remote and connects to the remote of headunit or if you have a stock deck to the acc of car found in wire harness of headunit. Plug in the RCA's to head unit, or get a converter to plug into speaker wires from car if you have a stock headunit.
Hi mate i had similar problem my 12 volt blow all good i thought every thing worked after fixing but i noticed my bass was weak subs would still move a lot but not pump no real bass coming from them .After eliminating most things i hooked dvd player to amp with cd inside to test if head unit was outputing bass and i found that my head units bass out put had a cry but fuse in headunit was fine and i was fused in 2 spots from 12volt source new head unit and all good again hope this helps
You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.
I have the same HU and the same processor as you. First I only used the chinch cables to the processor, and from the changer.
The improvements you make; your headunit DAC and your chancher DAC wil not be used anymore. The differens; normal with a cd you convert a digitalsignal into analoge, in the HU or changer, and then you make it digital again in the processor, en put the signal analoge into your amp.
The advantage is; the processor uses the famous Burr Brown DACs and that is know by its good sound processing.
