What amp for my needs?

[93civEJ1 10+ year member]

I have 2 8" 4ohm speakers that I am about to hook up. They are both rated for 300watt RMS each, with a max of 600. I am guessing the best deal would be to hook them up to each other for a 2 ohm load and run a mono amp? Is that what you guys would do? If that is the case can you suggest an amp that would power these two speakers that is not expensive. This is a low budget build.

Also, when I have two speakers ran to a mono amp, when you go to set the gains with a DMM, would you set the gain to see 600 watts at the DMM (300 for each sub)...or would you set the gain just until you see 300 watts? Sorry, I am still learning.

I also found this amp that has decent reviews....is not expensive, and seems to meet my needs for a 2 ohm load? suggestions??

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

Thats as about as low of quality I would get even though I wouldnt get one but with a budget likes yours you cant be picky.

Maybe even these - F700-1 CADENCE AMP MONOBLOCK 1600W MAX SUBS SUBWOOFERS SPEAKERS AMPLIFIER F7001 (812902006260) | eBay

Thanks for that post. Helps out.

I was trying to aim for under 100$ if at all possible. :/

110 is the cheapest ur gonna find that will do anywhere close to power. Maybe u can find a used amp on here but GL $100 for 600watts gonna be a hard find at that price point.

I'll also recommend the MB Quart FX1.600, it's a solid amp for cheap.

The amp you posted in the original post, is junk.

Pretty sure there is a "Sticky" for setting the gains using a DMM, but you aren't going to read Watts: you're looking for Volts.

To get a basic idea what voltage you should set the gains to, you can multiply the RMS power of your amplifier's output by the final impedance of the speaker(s), then find the square root of that number. (If you're using an amplifier that has an RMS output greater than your speaker(s) can handle then use the RMS rating of the speaker to determine what voltage to set your amp to.)

audiopipe apsm-1300 will do around 700 at 2 ohm for $108. I have one if you have any questions, best bang for the buck, and then you have a little headroom if you want to add another sub

thanks...I already have all of that down...just asking about when you have 2 speakers as the load, on 1 channel.

Finally unbanned. ha.

The amplifier cares not if it's one speaker or 100 speakers. All that matters is the finally impedance presented to it.
