Nedd help lost, no output on speakers

[337ram 10+ year member]

Ok I have two component systems in my truck, both ran through a kenwood 5 channel amp, a couple weeks ago I lost all channels except on tweater, which i thought was wierd because its mid going to that tweat wasnt working. anyways I picked up a new amp, alpine pdx5, been wanting one for awhile due to space, hooked it up and the same thing, only one tweat playing. Where do I go from here? My deck is a pioneer 4200, could it be I burned my outputs?? Just looking for direction, what and how to check next

if you have "component sets" with passive x-overs and only the tweet is playing it is (or was )not the amp /// sounds like the mid took a shiz or the x-over did ..what brand components? might have over heated the x-over and popped them

test all the drivers separately with a dmm or a batt good luck

and just a tip // when ever you are trying to diagnose a problem / just start @ the end and work you way back I.E. test speakers they good test amp it good move on to deck etc... when you isolate every thing @ once you may never kno what was wrong or what did it.

they were kenwood exceleon 6.5 less than 4 months old, this ***** if I blew them lmao. Ok couple more questions, can I use my dmm at the amp itself to see if there is any voltage going out to the speaker? If yes any idea what kind of V to look for. If I am not getting any V, then where should I go from there?

just set dmm to ac voltage and while playing music adjust the volume up and down and you should see the voltage on meter change

if getting nothing then test rca same way (red lead on cntr and blk lead on jacket ) if have signal there and nothing on output amp is bad

Ok thanks going to go check that

Ok my xovers are shot, another stupid ?, do I have to use the same xover that came in my component set or can I buy diff ones? If so any decent cheap ones out there you can reccomend??

need the same crossover - i.e. same component values.

the inductors are usually fine - it's the capacitors that blow. look at the value (in MFD or uF) and buy replacement caps - this time increase the voltage rating (63V should be fine). there will be a cap on the tweeter and woofer circuit - different values for each. you need non-polarized capacitors, either axial or radial (depending on the crossover configuration - i.e. wire on each end or both on one end).

if you have no idea what any of that means, send them to me and i can repair them.

how much you charge to repair x overs

how much you charge to repair x overs

depends on the crossovers. it's typically an hour or two + parts. PM to discuss details, and i'll give you my phone # to talk it out.

repairing passive crossovers is fairly easy - once you have the parts. i can also build custom crossovers or build replacement crossovers. i can measure actual values of existing components if values are not known. i can also test and run impedance plots of crossovers.
