I have a panasonic HU that powers up to 50Wx4 max, around 22 rms I believe.

I installed some boston accoustics 6x8's and I just can't get them to hit.
Every review I read on line says that have awesome bass response...
Is it not realistic to expect an aftermarket head unit to drive these?
At low volumes, the speakers do sound amazing... crystal clear... but I can get no boom!

Does anyone get boom out of their 6x8's are do you rely solely on a sub?

Thanks...

 

Need mo powa.

Even saying the deck will do 10wrms per channel is far fetched.

 

Seriously??


I haven't measured it, but it's advertised at 25W

Anyone got a 4-channel amp they'd suggest?
Push around 60W per channel RMS, I'd guess is what I need...

 

"Boom" is a relative thing. It can mean something different to you than it does to me. I suppose that you are refering to bass. Well, 6x8s are not going to offer you anything in terms of true bass. Most are rated down to 70hz or so. That is midbass, not bass. Even if they are capable of 50hz, that still is not "sub territory". And because of power supply capabilities, HUs are NOT the way to go if you want to "boom". Adding a decent amp will make the speaker able to play that 50-70hz range LOUDER, but it still is the same frequency. But maybe that's what you are looking for. But do not expect them to cave in your chest with 20hz. My thinking is the reviews you read probably should have said "awesome midbass response". Remember that if 6x8s were capable of "booming", as you call it, there would be little need for subs.

 

Well said. If you want real bass, get a sub and amp. The deck will push those 6x8s just fine. Put some bass blockers on them, and they will play louder.

 

Excuse me? Bass blocker make speakers louder? What models!!??!! Ill have to carry these magical instruments of power in my store!!!!!!

Absurd.

The deck puts out 25w at some ungodly voltage you will never see from your cars battery.

If your sytem is adjusted and you lean on the **** and it distorts, you most likely need more power. Of all the highs the 6x's require the most power. Of all the highs (excluding high end comps of course) the 6x's need an independent amp more than the others for that reason.

Heres an analogy. Imagine your average 12" x 12" 4 channel amp that does 50x4. You expect me to believe they fit that amp, the cd transport, tuner, and all the other fine pieces of electronics into that little CD player chassis? Sorry, thats not happening.

Besides, what is the fuse rated at on the power wire from the deck? Do the math.

I rest my case.

 

They will play louder without distorting as soon from low bass they cant handle. Sorry I didnt spell it out clearly enough. You should carry them!! They work pretty good!!



RMS Power: 25W x 4- what, a headunit isnt capable of putting out 25W ? Without some more info like at what distortion level or current draw, you cant really say that. And current would be more helpful than voltage to get more power.

Sure, or filter out the low frequences and it will allow it to play louder because it isnt having to put out bass it pysically isnt able to handle. Im not saying they will get stupid loud, but taking the strain of low frequences off the speaker WILL allow it to play louder. Research it sometime.

I agree. But how many people read the max ratings on a deck or amp and believe it?

As do I

 

Caps wont make up for lack of power. A deck will not properly power 6x8's. Run them yes, power them well, no. That is just one more fact you cannot deny. Whats you day job besides halfazzing answers? I run a car audio forum and a local shop. I am far removed from the most intelligible guy about car audio but these are indisputable facts. Decks dont properly power most aftermarket speakers. Need an amp, even a cheap one, to make em sing! I understand what you meant by the caps. Thats not what you said. If your goin to answer the question ...........

Caps dont make the speakers louder period. The effect the ability to play louder. As you said......the second time.

Want to get more from that money you wasted on car audio highs? Show em an amp. Amps that make small power are a dime a dozen. The correct answer was....amp them, with perhaps some deflex pads behind, to get the midbass to come alive. Oh and, dont forget those caps!

 

"A deck will not properly power 6x8's."

Sure they will. Just because the deck doesnt EXACTLY match the high end of the RMS power ratings, does NOT mean they will not be perfectly happy with moderate deck power.

"I am far removed from the most intelligible guy about car audio"

Yes, I agree. I am too, never said I was.

"Need an amp, even a cheap one, to make em sing! "

Ok, so your saying a cheap amp with overinflated power ratings, lots of noise and distortion, will be better than 22 clean watts of deck power?? LOL Sure, add an amp if you want to. I never said not to. But at least pick a decent amp.


"The correct answer was....amp them, with perhaps some deflex pads behind, to get the midbass to come alive."

Funny, I have never needed "deflex pads" to get awesome midbass. Dont use bandaids, do a real install.


"I run a car audio forum and a local shop."

Judging from your answers, a shop I would NEVER tell anyone to visit. Just because you own a audio shop, doesnt mean your the expert here. Im not an expert either, but you dont see me telling everyone Im MECP certified and own Pioneer electronics and to only listen to my opinions either. I can get midbass without "deflex pads"
Do you get an attitude with customers just because they asked a question, or had an opinion? Or because they didnt have what YOU think is the best equipment? I feel for your customers if you treat them the way you do on here.

"Caps dont make the speakers louder period. The effect the ability to play louder. As you said......the second time."

Where did I say that? I said the speakers will play louder by taking the lows away from them. Mabye if you werent so intent on arguing with someone you dont even know or their level of knowledge, you would have read it right the 1st time, and we wouldnt be arguing. hookd on foniks wurkd for me........

 

22 watts is THE MOST you will get out a deck with all four channels combined. Not enough to properly power aftermarket speakers. Period.

Deflex pads deaden the door panel area directly behind the speaker. It is designed to prevent cone break up. They eliminate standing waves and even enclosure resonance. Which means.....it distorts less and you get higher volume.

 

1st time

2nd time



Most already have some form over "xover" attached. Not always.

 

Fine, Im not going to argue with you about that anymore. I completely dissagree. You just wont see the full volume they are capable of. But still get plenty loud, if thats what your after, and sound just fine.

Never used them. I guess I learn something new everyday

 

One thing being "argued" is like splitting hairs. In this case, if a HU produces 10 watts RMS or 22 watts RMS is of little significance. It is still not suitable for what the original post is looking for, in his words, "boom". I've seen similar things for 30+ years. People want equipment to "do" something beyond it's capabilities. Example; an acquaintance bought a "1600 watt" Rockwood amp(fine print advertised 100x4RMS@4ohms) at the flea market for $75, a pair of 12" Xplor subs(not Xplod) for $50, and a dual truck box for about $25, and then wondered why it didn't "pound".

 

I decent 6x will thump is muddy bass'd head off if you show her some powa! 6.5's are cleaner imo, but that is another post entirely.

A 6x8 with a 1/2 stick of dynamite will definitely boom. Without it, tho all you get is some decent midbass.

 

lol

anyway, i think i really need some bass blockers. my stock speakers start sorta 'popping' at higher volumes.
