Soundstream?

[Ffej]

Looking for a class D 100W X 2 amp (nothing special but not junk) for two 5.25" coax door speakers and stumbled onto to this one. Worth $98 or is it an expensive paperweight?

PPI Black ice amps for the price and if its a budget build.I've had better luck with them than soundstream fwiw.

Soundstream is budget minded really. With the exception of their Reference series, which is close to what they offered in the 90's. Yes I know I have them as well but I'm on a budget and if I could I would take a better brand. But for now, they work.

That 0.5% THD is scary. You wanna look for an amp that has something better like .003%, for example, or so.

Never seen a class D amp with .003%. I'm not even sure an A/B gets down there.

Looks like their Black Ice amps are A/B (D for the mono).

This amp will stomp any soundstream or ppi which are basically twin boards between those companies.

I put this head to head against a ppi phantom 600.2 and this amp absolutely smoked the phantom. Usually costs 229. Get it while its cheap.

Fyi phantom is way better than black ice and runs a lot pricier.

for 100, nothing will beat this amp. Absolutely nothing under 100 will come close half its performance.

Looks like a great amp for the price. It's an A/B though. Would this one be a whole lot more power hungry than a D with similar specs.? Sending most of my electrons to a HDP 1. Just don't think I'm ready for an alternator swap yet. I know I'll get there though. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I have this Soundstream amp

https://www.amazon.com/Soundstream-TN4-900D-4-Channel-Tarantula-Amplifier/dp/B009NLNY14

I love it.

I do not use the internal crossovers on the amp.

I am using an Audison bit ten D for crossover points.

I was skeptical at first but I am glad I bought the amp.

Zero problems after 2 years in my daily driver.

I am running the amp "active" The crossovers are set to bypass.

I was looking at a JL 600/4 but for the price I'm going to stick with the Soundstream TN4.900D for a little while longer.

There's probably an extra zero in there, and even .03% at rated power is totally inaudible with music playing.

In this power range, class D vs a/b is not much of an issue unless you're building some micro system using a little bitty battery.

A 200w a/b's might draw 6-10A most of the time. A class D 4-8A, or somewhere in that range.

I would personally not hesitate to buy the SS. The PPI ion series (similar, if not the same inside) has had a couple dyno's and I was surprised to find they do rated power.

0.5 vs .03% THD (or any other fraction of a percent you want to hypothesize about) is not a factor unless you just like to see low numbers you'll never hear.

You almost answered another question I have. I been out of the game for a few decades, and I don't remember amps having built in crossovers. Heard they may be less than desirable so I'm planning on an active crossover myself. Question is, how to you bypass the amp crossovers? Do you simple turn them to their limits so there isn't filtering on the amp's part?

On this amp all you have to do is set the crossover switch to full

very easy

Class D is mainly for sub amps. Class A/B is usually for other speakers.

Really tho, you don't needs class D amp to run a pair of 5.25" coaxial speakers.

That's not true at all

Most people will not be able to tell the difference from class A, A/B,D, G, or H

Tons of people use class D amps on their mids.

Class D for full range all day.

And it's not most can't tell the difference. It's everyone except papermaker that thinks he can. If the golden ears can't tell them papermaker has diamond ears or some ****.

Also 1% THD is perfectly fine. Nobody will hear that. Even 10% is hard to hear
