Will my preamp change the Frequency response of my amp?

[lovinthehd]

Well I use 4 bic america dv62si, each speaker is rated 150 watts RMS @ 8 ohms, and my Samson dj speakers rated 250watts RMS @ 8 ohms but I only use them when I littin to the radio but too many issues with power on my receiver so right now just need the power for my 4 bic america dv62si, but I don't have the space for all my other speakers I have sitting around not getting used and my Yamaha rx v995 is always getting used and my Klipsch sw 112 subwoofer which is very powerful 300 watts rms 12" speaker and a course I use this setup for my computer.

How are you planning to use four speakers with a stereo amp, are you doing that now with the receiver? The max wattage ratings aren't so useful in planning for an amp as the sensitivity rating, which will tell you how loud your speakers can get with a given amount of power. Google spl calculator.

 

[Aaron Bilger]

Those watts on speakers are maximums. They don't need but a small percentage of that to deafen you.

Ya they are very loud at low volumes but still this is also for my new setup later down the road in 1 year, btw, I have everything I need but the amp the bookshelf speakers I use in something else but I have other floor speakers that need the power.

Well this receiver is a 5.1 receiver is all surround sound but I don't use the surround sound most of the time I got it because it was cheap of $130 6 months ago and nothing wrong with it but I have gained the issues with it over that time. BTW, it is meant to have 4 speakers on the main.

Oh and i'll just use the speakers @ 4 ohms 2 speakers per channel I here people all the time use 8 ohm speaker and wire them up to 4 ohms you take 2, 8 ohm speakers and hook them together in the right way and you will get a 4 ohm load from the speakers. People say and even my dad will use some speakers that are 8 ohms and wire the speakers together and get a 4 ohm load now i'm not 100% from the damage rate of the speakers but I have ran these 4 bic america dv62si speakers at 2 ohms by mistake once on my receiver its a different yamaha I used them like that for 5 minutes by mistake but I can't tell of any damage from anything.

A nominal impedance rating isn't good enough to do what you're doing....a speaker rated at 8 ohms often dips as low as 4 or 5 ohms, as it is specifically frequency dependent (the nominal just being what it approximates mostly). Google speaker impedance plot images....

This could be why your receiver is crapping out. Most receivers don't like running two eight ohm speakers in parallel.

Where do you see it is meant to have four speakers on the main?

So what you're saying is i'm fine no damage to any of my speakers then if ran at 4 ohms and wired up correctly? And will I be able to play loud as I want with them while I stay in the rms power?

 

[everettT]

. BTW, it is meant to have 4 speakers on the main.

Well just because it has a speaker AB setup doesn't always mean it can run both at the same time, it depends on the load it sees, fyi.

No, No i'm running my speakers @ 8 ohms on my receiver and the ohm switch is @ 8 ohms i'm only using the main channels A and B channel A runs 2 speakers and channel B runs 2 speakers that's 4 speakers i'm doing it right.

No, I wouldn't do what you're doing, especially not with the receiver using both on the L/R outputs. The Crown might handle the load but it isn't a good idea. Running two speakers off a single channel has acoustic issue potential as well. How loud are you needing?

 

[everettT]

Yamaha does state in the manual " either a, or b, or both. What the manual doesnt say is they expect you to understand what is being hooked up to it.

Still doesn't mean the amp can handle simultaneous play well. That said, I have an old 5.1 with the A/B speaker thing, too, and do run two pairs of 8 ohms (one in the garage, one on the patio) simultaneously at lower volume; it'll shut down at higher volumes. The ohm switch on a receiver is usually a limiter to protect the receiver, it doesn't literally enable lower impedance speakers.

This is the main channels look like

OP,
Could it be that the way you've wired your speakers has brought about the issue you have with your receiver? You might want to just set back and THINNNNNNK! I suspect that your desire to make something great from too little money is the real issue. Save up!

This receiver goes to 4 ohms and 8 ohms it's a switch

Iv'e had this receiver little over 6 months you can't send it back you get 14-30 days to return it you wanted to.

Ok so everyone has their thoughts which on is best if I make my budget maximum of $250-$290

That's not unusual at all, but do you know what the switch actually does? Most of us ignore that setting and leave it at 8ohm, try this article https://www.audioholics.com/audio-amplifier/impedance-selector-switch-1

Ya it changes the ohms for the speakers if you used 4 ohm speakers you put the thing at 4 ohms, if your using 8 ohm speakers then set the thing to 8 ohms with the receiver powered off.
