Great sub and bad amp?

[MAkahveli 10+ year member]

O.K. recently I received my sub which wasn't what I thought it would be (Single voice coil) but work for me. Its an eclipse 10" SW8102.4 1000W max and 500W rms from their aluminum series 4ohm. And my amp which a friend needed money bad sold me his for $40. It's a Boss c700 2channel 1200w max and 600w rms bridged at 4ohm. I know first thing to add is a cap to the setup, but how do you guys think shoud I just get another amp? anything to worry about? Any advantages or disavantages of it? Or don't worry about it?

ummm

caps are eye candy and put more of a strain on your elec system.

that boss amp is useless.

Don't add a cap. You would be better off putting a cap in your own foot.

Step 1: Big 3

Step 2: Proper wire sizes on the install (4AWG)

Step 3: Install what you have

Step 4: Enjoy the bump

Step 5: Look for a decent amp

Step 6: take back the audiobahn amp that you purchased when you thought it would work out for a decent amp //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Step 7: Repeat step 5.

No it wouldn't.

O.K. my next choice for an amp would be a phoenix gold class d amp. not being familiar with class d amps is it a 500w i want or 1000w? Just that looking for them on ebay they don't specifically state the rms as if the amp always plays at its max.

When you find an amp that you are in and question the output, grab the model number of the amp and check the specifications on the manufacturer's web site. In this case with PG, go over to PhoenixGold.com and pull up their products page. It's the only way you will get accurate information. If you go with what you find on Ebay, you're going to end up purchasing a 240W RMS class d amp with a max power of 1200W (1 ohm @ 14.6V vs 4 ohm @ 12V). The key is... check and double check.

O.K. I did that but my main question still persists. Is there an RMS to class D amps or are they always suppose to play arround they max setting? I know this should be in the amplifier sub forum but also what makes an class AB amp different from class D?

 

[Spr0ket 10+ year member]

Class AB amps are specifically designed to play a full range. They run a bit hot due to the switching between the loads. The Class D amps can't play the upper range without distorting quite a bit which makes them perfect for subs. The class d amps are most always mono unless the circuitry has two class d amps side by side. Easy way to look at it, AB = full range, D = subs.

All amps have an RMS rating. You should always set your gains to RMS levels or lower. Peak ratings are meaningless. Some makers will rate their amps differently based on voltage and ohm rating making one amp look better than another when it's crap.

No, class D amps have an RMS rating too
