Amart88 Posted August 10, 2013 Author Report Share Posted August 10, 2013 Well, now that they are strapped, the master (working amp) completely shuts off when I crank it up... If I switch the master to the bad amp and slave to the good one, I get very little bass. Bass boost is turned off always. on HU and amp. What I tried: I Tried switching the RCA's every which way. flipping master/slave a few times. Strapping them. (now have new problem) ^^^ Turning gains down lower. Voltage is constant 14.7-.9 Everything is secured. What I'm going to still try: Checking ohm load again replacing amps fuse. measuring rca sheilds? Need some more info on that. I need some more explanation of checking the RCA's and what to look for. Also anything else to maybe try before I send this POS somewhere. I figure it's the bad amp causing the good one to somehow shut down while strapped. Crescendo have not got back to me yet. My 2005 s10 blazer build. 4 zcon 18's walled.

n8ball2013 Posted August 10, 2013 Report Share Posted August 10, 2013 Swap your woofers around what was on amp one kove to amp two see if the problem follows. Test each woofer alone Try swapping your rcas and jumper from the other amp. I dont like jumpering id prefer the y adapters Maybe swap rcas if possible THERE IS NO BUILD LOG! 1998 Chevy Silverado ext cab Alpine CDA-9887 4 Team Fi 15s 2 Ampere Audio TFE 8.0 2 Ampere Audio 150.4 3 Digital Designs CS6.5 component sets Dual Mechman 370XP Elite alternators inbound! 8 XS Power d3400 6 XS power d680 Second Skin Stinger Tsunami Wiring Sky High A Real Voltmeter not a piece of shit stinger.

Amart88 Posted August 10, 2013 Author Report Share Posted August 10, 2013 Same head unit as your car too? Yep, Kenwood KDC-345u I believe. I switched the woofers and the problem follows the amp. Also swapped the RCA's when they were separate. The problem still continued. Even running just the "suspect" amp it put out jack all for output. Even lower output voltage.

tacomaguy1 Posted August 10, 2013 Report Share Posted August 10, 2013 No way to borrow an amp to rule out hu or rca's? Team Flex Issues Link to comment Share on other sites More sharing options...
Amart88 Posted August 10, 2013 Author Report Share Posted August 10, 2013 No way to borrow an amp to rule out hu or rca's? No. Sadly, nobody remotely close o me runs this type of gear. I wish I could though. I don;t think it's RCA's as I have ran the amp by itself with no luck and the other works fine on the same ones. I am going to go out and measure the rca voltage right now. Just weird that the working one shuts off now. My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
n8ball2013 Posted August 10, 2013 Report Share Posted August 10, 2013 First thing I would do is swap ina new head unit. even if you "borrow" one from a best buy or whatever you call it up there.

CJ18 Posted August 10, 2013 Report Share Posted August 10, 2013 Do you have any friends around that you could use their vehicle to put the bad amp in to see if it works? Link to comment Share on other sites More sharing options...
monkeyleg Posted August 10, 2013 Report Share Posted August 10, 2013 Sounds like a nightmare. I would go buy a headunit and hook up everything outside the car with a battery. Rule out RCA's and headunit. Return everything when done troubleshooting. Google it Link to comment Share on other sites More sharing options...
