I have this
(http://www.crutchfield.com/S-V8nL1LR...61a&tab=review
) amp and Infinity Kappas. For some reason I am missing hard bass lines
and hard bass. Is there something wrong? Well, sure it is. I tried
adjusting the crossover and I still have that problem. It is annoying. I
have no problem otherwise. Should I go with separates?

My first question is - have you had good sound in that car in the past?
Because if you haven't, then you may have problems with the car's
acoustics, needing sound proofing, eliminate SPL, Dynamat, etc.

I have a car with similar problems. I don't think the addition of an
amp is the answer or cause of these problems. In my case, the rear deck
has a number of holes in it, so I get speaker pressure loss until I
plug them. Then there are the plastic body panels which absorb a lot of
the sound, and I have to use sound deadener there.

Well how do you know if that is the problem if you cannot hear it? I have
had good sound as far as hearing hard bass before I put an amp in. I hear
very low lows, but no hard bass. I heard even less before I switched head
units.

You may have a phasing problem.
Check that all the positives and negative speaker lines from the amp are
going to the positive and negatives of the speakers

That's pretty ignorant, isn't it? NOBODY in this group can hear your
car, so by this logic, how can you expect ANYONE to help you?

Go away, troll.

YOU are ignorant. I did not mean that in a smart ass way, I meant it in a
"I cannot hear the bass" way. Meaning, how does one know what the problem
is since I cannot hear the hard bass? I'll take the blame since I did not
make myself very clear.

Good 'ol helpful Mat. Though he is half right, none of us can really know
what's wrong (if anything) without listening. The best we can do is make
educated guesses based on experience and the info you give us.

Enigma's idea of checking the connections so that the positive goes to
positive and the negative goes to negative is a VERY good one. Bass is VERY
suseptable (because bass is omni-directional versus treble) to cancellation
if connected out of phase.

If connected correctly, and the problem is still present, try connecting
them out of phase (just switch around ONE of the speakers connections).
It's possible that with the addition of the amp, you have a situation where
the distance between the two speakers is creating cancellation. It's a bit
of a long shot, but worth a try and easy to do.

Make sure your high-pass filter for these speakers are not set too high on
the amp. Depending on the X-over slope (and whether you own a subwoofer) 80
Hz is typically a good starting point. If you have no subwoofer, then would
want to go lower, perhaps 40-50Hz.

Also, this amp has bass boost controls. Try adjusting these to get the
sound you want.

Good luck,

Thanks. It hit me again today. I was listening to some Sam Cooke (yep) and
you know that older music his hard bass heavy. The hard bass was not even
there! I have notice that in a lot of different musical types. It's the
good thing I don't just listen to rap or I would never have noticed it.

I will try the rewiring of the sub. I did kind of recall the positive and
negative being on different sides on the inside of the box than it was on
the outside. I could be mistaken, but I will try the rewire. I was
thinking of getting separates if this continued. What is a good crossover
frequency to set the sub at? I have it at around 320hz right now. The
lower I go even more hard bass is lost. I will try the bass boost thing
again also. See, I only have one sub (4ohm) bi-wired for 2 ohms. It used
to overheat with my last, 3 year old head unit. Now I turned the sub down
to prevent this. However, the hard bass is not there. It is a stereo sub
hook up. My new head unit did not specify a right or left channel of the
RCA jacks. This part of the system is very annoying. Everything else is
right.
