Not sure if I should put this under speakers or amps, so I am going to do both.

I found a few plate amps at Parts Express, but not much choices. Any other sites that sell this type amp for building powered subs?



EDIT....100-125 watts is what I am looking for.

Re: Plate amplifiers?

What features do you need you aren't finding at parts express? Plate amps are pretty simple items. You also can't have too much power, so the BASH 300 wpc they often have for $125 shipped is quite the deal.

Re: Plate amplifiers?

Just wanting to see other ones, they only had 2 real choice for the wattage I was looking for. My sub is ratted at 150 rms and 300 max, so I was really looking for something around 100 watts. Which matches my reciever output, and doesn't push the sub too hard....seeing as how it's a small room 100 watts should do fine.

No that I have looked around a little more I see that PE is they way to go. This one should do me just fine 100 watts @ 4 ohms...... Parts-Express.comayton SA100 100W Subwoofer Amplifier | subwoofer amplifier subwoofer amp sub amplifier sub amp plate amp DayAudSubAmp050109

My reciever has a single out for the sub. I guess the amps paper work will tell me how to hook it up?

Wattage ratings for subs are totally useless when using them in a home theater. Most of the time they will run out of linear excursion long before reaching their thermal limits. If you model your sub with Unibox, you can turn on the filter option so you will get a more accurate representation of how your sub will perform with a plate amp that has a subsonic filter.

Using a sub cable (check out Monoprice.com) you connect your receiver's sub out to either of the line inputs of the plate amp. It's that simple.

FWIW, matching the power of your receiver is meaningless at best. Where did you get the idea that should be an objective?

I agree with John, I would shoot for the maximum your sub can handle safely, it would be one less thing to upgrade later on if you get different equipment later, you could carry over your sub to next system.
