Question on matching speakers to amp?

[ditosdad]

The speakers (not subwoofer) I am looking at are 2 ohm. Can I wire an amp to run the speakers in 4 ohms or do I need to bridge the amp to 2 ohms?

Do what? Give me the amp brand and model number and the speaker model number

Which amp? Pretty much all amps are 2 ohm stereo stable and have corresponding power ratings at 2 ohms. You're fine running 2 ohm speakers off virtually any amp.

Looking at the JBL P660C speakers and the JBL GTO804EZ amp. The reason why asked the question is that, I would think running in a non-bridge mode would be better for the amp long-term. I could be wrong?

That amp gives you 100W per channel at 2 ohms, which is more than enough for your speakers. You don't need to bridge anything and it has no bearing on the amp in the long run.

Agreed, don't bridge. Running below minimum is only ok when you have the electrical for it, and usually only on class D monoblocks that are built to high standards. You're right, not bridging in this case will be better, because you're running below minimum ohm load. Glad to see a new guy buying quality stuff though! Most people would just buy Sony stuff and be done. Who am I to talk, I have Sony mids and highs lol

That sounds good then! I thought running in 2 ohms was bridging that amp.

I guess one more question to that set up. I wanted to keep the power close to the rated RMS power on the speakers. Is that amp a good choice based on the power?

100 vs 90 is basically ideal.

Make sure you don't just assume when it comes to this. Keeping the RMS close isn't really a thing and you shouldn't be buying equipment based on that. You can actually get most speakers to perform well even at 40w, but you can always buy an amp that's more powerful so you can have healthy headroom.

The amp is a good amp. Make sure you spend some money on sound deadner. I used peel and seal from Lowes as mine, does the job for me.

Awesome, I will look into that!

With my budget, I figured it was better to have cheap deadener than no deadener.

A guy at work used it before he talked to me. It's leaking out all over his car and smells like ****.

Did he put it upside down in his trunk? Trunk has no air movement, my doors do. It stays cool.
