amp cutting off

[bigchevyboy 10+ year member]

when I turn my front stage amp up to a certain level it cuts off, why do you think its doing this?

what is the ohm load at the amp?if its lower than the amp is capable of handling then it will go into protect if you try to push any power through it.you may have to wire your speakers in series or a combonation of parael series to get the proper ohm load.or buy a new amp that will work if you plan on running multiple speakers i would suggest getting an high current amp that can handle low ohm loads with no problem.an the lower you go the more power you get to a point.good luck

I have a RF450.4 with 4 6x9's and 2 4x6's and 4 tweeters running from it. explain that ohms stuff you were talking about.

that could be your problem.....you may have the amp running at too low of an impedence. You have 10 presumably 4 ohm speakers running off a 4 channel amp .

Do you have two sets of component speakers? Or do you have 4 coaxials and 4 tweeters? How are all your speakers wired to the amp?

The amp is most likely cutting out because it is going into thermal protection. You are not supposed to play with the gain knob like a volume knob. Do a search for a gain setting tutorial.

x2

and do a search on ohms, i think our speakers are wired down to low of a load, and your amp cant handle it.

I have the 4x6's and the 4 tweeters running to the front channel and the tweeters are wired to the 4x6's on each side and they are bridged. 6x9's are ran wired seperat to the reat channel and they are bridged. is this my problem?

just take a multi meter set to ohms and it will tell you what the ohm load is.if its below 2 your probably to low.you can either mess with the wiring or by a high current amp.good luck.

You owe me a couple hundred brain cells. I lost them trying to understand what you mean. Please draw a diagram because what you said makes no sense whatsoever. Look up the terms series, parallel, and bridged. Learn what they mean and use them to describe your setup. Thanks.

But first...are you saying you hooked separate tweeters up to your 4x6 speakers in a parallel configuration? Do you have capacitors on them to block out the low frequencies? Or do you just mean you have 3-way 4x6 speakers in the front of your car?

Ow.

sorry. I have my tweeters ran to the 4x6's then from there they are wired to the amp. I have no low frequency at all to those.

From the sound of things you hooked everything up in parallel on the rears. IE. you have a bunch of speakers + terminals wired to one + terminal on the amp, and a bunch of the - terminals wired to the other - on the amp. This presents a very low impedance (low ohms) to the amp which is bad for it.

In the fronts, if your tweeters are wired to the 4x6's speaker terminals then you'll have the same frequencies going to the tweeters as you do your 4x6's unless you have a crossover between the 4x6's and the tweeters. This is very bad for tweeters. You still won't hear low tones from the tweeter because they are incapable of producing them. Do you have any crossovers / high pass filters anywhere? Or are you talking about the tweeters built into the 4x6's?

 

[bigchevyboy 10+ year member]

I have the high pass filter on the front channel. so should I run each speaker seperately to the amp?

draw us a diagram of how it is wired cuz i have no idea what ur trying to explain

 

[bigchevyboy 10+ year member]

ok here it goes. wires from 2 tweeters runs to left 4x6 terminal in turn runs to the amp. wires from 2 tweeters runs to right 4x6 terminal which in turn runs to amp where I have left and right wires bridged in speaker input.
