Is this true?

hey guys, i went to the local audio shop here in town(stereoman) looking for a line output converter.

he told me something id never ever heard of before, "you have to be careful with the whole impediance thing. the stock speakers in your car now are probably 10 ohm, and if i hook an amp up to the other end of the convertor it shows the amp in the head unit a different load, maybe 2 ohm or whatever, and therefore thatll fry the headunit". is this crap?cuz ive never heard of it. rcas arent power wires, theyre not showing anything a load right?
help me out guys, thanks

So you going to run an LOC to an amp to amplify your stock speakers?

Adding a Line Level convertor will have a slight effect on impedence but it will NOT FRY YOUR HEAD UNIT! The difference is almost nothing. Dont worry about it. Just dont buy a cheap one because they dont sound good.

no, LOC to run an amp to run a sub. a ordered the scosche one from crutchfield. it looked decent, reveiws were good. and i picked up my ultra linear UL-1500 x today. gorgeous.
cheers

p.s. this is in an 03 cavalier, reason i say that is the car sucks so the head unit probably does to. haha

Then what the guy at the shop told you is irrelevant, hes talking about an LOC and 10 Ohm stock speakers when you want to run the LOC off the deck to an amp to a sub....you wont have any problems.

Good luck with the new amp!

and as for the Cavalier, I sell car parts so I love GM products....lol

sorry i think we got a misunderstanding here..
im running the LOC off the stock speakers, to run an amp, to run a sub.
and same how running an LOC off the rear stock speakers in my cavalier will fry the deck?

What the guy was saying is that putting an LOC & amplifier in parallel with his speakers could cause his stock HU to see a dangerously low load which could cause it to fry.....


Well now, the input inpedance of you amplifier is going to be on the order of ten thousand ohms...... and you can add to that the resistance the LOC will provide to knock the high level signal down......



The guy you were talking to is clearly a moron who dosen't know what he is talking about.... please go back and ask him to STFU and suggest he should probably find a new job, on my behalf....

I agree. Unfortunately you have encountered an idiot. Use small words and back away slowly. Should you ever return to that store, avoid him at all costs.
