I have a '99 Dodge Ram Quad Cab with the Infinity 6 speaker sound system (4
speakers/2 tweeters). The head unit is an AM/FM/CD/CASS 1.5 DIN with
steering wheel controls. This system has an amp integrated in each front
door speaker. The right front door speaker quit working. I swapped the right
and left front door speakers and the problem followed the speaker so the HU
or wiring is not my problem. I don't want to lay out $187.00 for a speaker
to restore a factory sound system. It's upgrade time. I want to keep the HU,
tweeters, and rear speakers and replace the front door speakers with some
decent aftermarket ones. I know the factory HU won't drive the system
without adding an amp, but I'm clueless about amps. I want to keep the cost
reasonable for a clean sound quality at a moderate level. I'll spend the
money where I need to, but I don't want to pay extra for a name on the box.
New rear speakers and a sub will be added later so expandability is a
consideration. Any amp and speaker recommendations?
Most any brand 2 to 4 channel amp will do you just find in this application.
Stay away from Jensen and other Wal-mart brands. I would not recommend
anything that is more then about 50 watts per channel as you are only
looking to run your speakers and not a sub. 50 will be clean and powerful
Thanks, Larry. I do want to add a sub later. Is 50 watts enough for that?
Crutchfield has a MTX Thunder282 70X2 and a Rockford Fosgate Punch 201S
50X2, both are tri-way capable and in my price range. Is 70X2 overkill? I'm
not out to win any boom competitions, but I find the factory system is
lacking in bass at moderate volume levels so the sub is going to happen in
No a 50 would not be enough to run all your speakers and a sub too, even in
a tri-way set up. You would have to have a second, larger amp to run the
sub, or buy a 4 or 5 channel amp to run them all.. I would go with MTX over
Fosgate, I (personally) have had a lot of problems with Fosgate, but never a
one with my MTX.. The Thunder, bridged would run an 8" or 10" sub with no
problem, by itself.
With a 2 channel running your speakers what you will run into is that you
will loose either your fade or balance due to how you will have to wire the
speakers. A 4 channel will prevent that.. A 5 channel will run the
speakers and a sub.
Other brands, Bazooka, Alpine, Kicker and all good amps that will be on the
lower cost side..
I don't want to lose either the balance or fader so I'm looking at 4 channel
amps. I'll add another for the sub later. Is it better to have an amp rated
higher than the speakers, or the speakers rated higher than the amp? I can
get a 60wX4, 40wX4, or 30wX4 amp, all priced within $50 of each other.
Oddly, the cheapest amp (Profile) seems to have better performance specs
than the other two (Kenwood). Is Profile any good? I found 2-25 watt rms
(Pioneer), and 6-45 watt rms (Kicker) speakers for about the same price that
will fit my truck. Would the best combination be the 45 watt speakers with
the 40 watt amp? Maybe the 25 watt speakers with the 30 watt amp? Would the
cheaper 60 watt amp be too much for either of those speakers?
Thanks for all the help so far.
These are the items I'm looking at (Crutchfield comparison pages)
From looking at just the tech data, I would go with the Profile. Are they
any good, the old Profile line was, the new one, not too sure about, only
really worked with a handful of them. Though, never had any problems with
them. Don't worry too much about over powering your speakers. They will be
able to handle a good bit more then rated AS LONG as it is distortion free.
You will blow your speakers with distortion faster then you will with clean,
A larger Amp will do nothing to your speakers UNLESS you turn up the volume
to where the full output is sent to the speakers for an extended period of
time. My experience is that a 45 amp, when maxed out will be so distorted
that the sound is awful anyway. That being said, I would rather have a 60
watts amp played a volume pushing 30 watts than a 40 watt amp pushing the
same. in a nut shell, larger amp and smaller speakers (capacity, not size)
is preferable over the opposite.
Nosey, if you are interested, I've got a Soundstream amp I can sell.
It's an MC245 and should be just the ticket for what you are looking
to do. Not going to win any major competitions but will make you think
you're able to. I can dig out the specs if you are interested. Anyone
that knows good amps knows about Soundstream. This one is from
the "old school" original designs from Soundsteam.
Actually, here is a link for the owners manual with all the specs.
