Since it seems research isnt your strong point, here is an exert from Crutchfield website that may explain to you what Ive been trying to much better. Ill also leave the web address here for you in case you may want to check for yourself.
Class A and Class B may produce a cleaner signal, however most of the signal spectrum is inaudible to the human ear. More efficient power means harder bass, period, and thats what you get from a Class D mono amp...
Since reading is not your strong point let me try to explain it differently. Efficiency of an amplifier circuit is NOT a direct correlation with how 'hard' your bass is. What is meant by efficiency when speaking in terms of amplifier circuitry is the power out vs the power in. In other words how much will it drain your cars electrical system vs how much power your sub gets. Your link/quote did not disagree with anything I said my last post. Please read next time and if you want to tell me how to research don't insult me with FAQ from Crutchfield that's like going to McDonald's FAQ for nutritional information.

Adding an outboard cap will add sound quality!!?1?? Is that what's wrong with my bose system

Instead, use a mono amplifier to power a 2-ohm load — two 4-ohm subwoofers, or 2, 2-ohm dual voice coil subwoofers, for example.
key word in the 1st sentence..."typically," they streeeeeeeeetch the meaning of that word 10 miles too much...which is a great selling point pov for crutchfield. scare the customer into thinking "typically" any multichannel amp is not capable of driving anything but 4 ohm door speakers.

simple question:
can my lil 4 ch amp... http://www.sonicelectronix.com/item_...dio-M489I.html handle a 2 ohm load?

answer: sure can, and def does!

a 2 channel amp...is a multi channel amp. crutchfield is telling me that "typically", its only good for 4 ohms. when all of their amps for sale are 2 ohm stable. hmm. typical.

If you're electrical is suffering from some issue that can't provide consistent power to an amp, and the amp can't store enough power for all the coming musical demands, then sound quality will suffer...yes.

If you did nothing else, and just added a cap, in those circumstances you could notice better quality in the performance of the amp...clean power in, more power out. Dirty power in, degraded performance out.

All I'm saying is that the claims of the cap improving the quality of the sound is not far fetched...I've seen it work, especially with continuous bass that puts a cheap amp at it's peek constantly. If the variables I mentioned above exist, you WILL see an improvement in performance by just adding a cap.

Of course, clearing up ground issues, and buying a quality amp in the first place can negate the need for a cap too. I'm not disputing that.

You aren't making the amp better than what it already is by adding a cap. All you're doing is allowing the amp to run at it's relative state, thus the signal coming from the amp isn't cripser or better, it's the signal that it is suppose to create. All cap is suppose to do is create consistant power to the amp, and if that's the case it isn't making the amp create cleaner, cripser sound is it?

By stating that a capacitor will help the amp create better and crisper sound is pretty far fetched. If it said it would help your amp run much more efficiently, than perhaps I would agree. Only way to make sound better is to filter out the unwanted frequencies and than amplify it. Last time I checked cap isn't a filtering system.

No youre quite correct, I was responding to a previous post, I mentioned earlier there were exceptions to this rule...many exceptions...but most amps can not handle the impedences mono amps can

I don't know? lol I think capacitor has it's uses but that's just me. Some sware by it and some don't. Whatever is what I say? Use em if you think they are for you but if not then there you go.....

To be honest most amps can handle the 2 ohm load regardless of being mono class d or a. I haven't had an amp that wasn't capable of handling the load.

But yes HCCA is not your typical amp.

Obviously mono amps has it's purpose in the caraudio industry!

I remember back in the days companies like Orion, Autotek, Hifonics, US Amps, PPI, Soundstream would all create cheater multi channel amps that would handle lower impedances!!!

Youre right...Im talking competition level however. My system, for instance, is bridged down to 1ohm mono..not many multichannel amps can do that. Im pushing 2 Kicker CompVR 12'' subs at 1ohm...Id like to get 2 more and bridge down to 1/2 ohm, I cant see a multichannel amp doing that

HCCA is a BEAST or an amp...

Yes the good ole days...
I can remember back in the late 90s havng a HiFonics Zeus amp advertised at 300X1 at 2 ohm...however I pushed 4 Zeus 12s bridged at 1/2 ohm with that thing lol

You made really good points. I took it out of proportion when I included the HCCA series amp to this thread. But I couldn't resist...

i have that amp...only its a 400 watt bridged at 2 ohms.

yeah im driving the older mtx t7500 2 12" sledgehammer enclosure with them. but they are way underpowered. the amp gets hot and clips under a load...i cant be bumpin it how i want to all the time.
