Blaupunkt München RDM 169
The Blaupunkt Munchen RDM 169 is a 1-DIN head unit which features flip-down faceplate, steering wheel-mounted remote, digital parametric equalizer, and has four preamp outputs, subwoofer output, and is rated at 40 watts x 4.
What people are saying
Maximum undistorted preamp output measured 3.2 volts and output impedance is a relatively low 101 ohms. Dynamic range measured in excess of –100 dB, which usually indicates some type of zero-bit gate.
The München’s user interface is surprisingly good considering the vast number of functions that the unit possesses. Overall, the München is a very slick, if somewhat complex, package.
Awesome sound quality. DPE is an awesome addition to an otherwise great head unit. Radio reception is of the quality i have come to expect from brands like Kenwood, and Pioneer.
I highly recommend this unit for anyone, especially if installing it in a european car, which it is designed to fit. The radio reception is unbelievable, and there are such a plethora of settings to adjust radio reception. This is a must for anyone that spend a lot of time listening to the radio, especially if you live in an area that has poor radio reception.

Remember that one-of-a-kind subwoofer Clarion released a couple of years ago? See photo below.
Clarion SRV303
Yes, that is a subwoofer. The SRV303 is a powered subwoofer that combines a 3″ speaker with a built-in 65-watt amplifier. All is a super-compact ported enclosure. You can place it under the seat of your small car, in the glove compartment for up-front bass, or any place that can fit a 330mm by 230mm and 72.5 mm thick box. Heck, that’s smaller than most car amplifiers.
But…
For something as fresh a concept as it is, you either make it and set a trend or forget about it. Most review of the SRV303 have been less than stellar to say the least. In other words, it does what it is supposed to do, but unless really do not have the room fit a real subwoofer and amplifier in your system, the SRV303 is a good option to consider.
Clarion’s description of “Just want to add a little punch to your bass without a lot of booming and shaking?” tells the whole story. Try it in your wife’s car or your “unofficial” second system. Try it for the heck of it.
Update
The SRV303 has since been replaced by the SRV314, which is a smaller 6.6″ version of the SRV303.

Sample Reviews
“I have had my 2 10w6s for about three years. I purchased them at a pawnshop so I do not know how old they really are, but they were in perfect shape when I bought them for $100 each. I agree with the statement that they are bulletproof. I have cranked them extremely loud, louder than they should have gone, without any problems. I have used two different box sizes with them and agree that if you go too small you lose the quality you paid for. I originally used .8 ft3 and they went so low that you could almost count the frequency. Now I put them in .65 ft3 and they hit unbelivably hard, although they are less efficent at the ultra low frequencies. I would not suggest going any smaller than .6 ft3. You would lose too much low end and think that they suck.”
“Tight, accurate, detailed bass. Loads of power handling. Can play super quiet or super loud and still be musical. Worth ever penny.”

6″ x 9″ two-way loudspeaker
I have been trying to search for a review on these 6×9s for a long time now; most of the stores that carry these do not have user reviews. Yes, I know the REF9612 has been discontinued, but these used to sell really well. Currently, the REF9632CF and the REF9633CF are the 6×9s offered by Infinity.
Still looking for that review…
Here’s from a buyer at Amazon.com, it may not be much but you still might pick-up a thing or two about what this guy—a certain Max Xiong from Denver said.
“I replaced my old and I mean “OLD” Bose factory rear 6X9 speakers. They were the paper type and had been sitting in the sun for like ages and the paper had seperated from the middle of the speaker. After replacing with the Infinity Reference 9612I OMG!!! it was clean, crisp and clear. No distortion of any kind even turning up to volume to max. The vehicle I have came with a factory AMP of 240 watts so It handle the new speaker perfectly. No complaints here… For the price, these are a STEAL…”
If there’s anyone else who knows of a good review for this product, please send them in; a link or your own review will do.

Compared to other 6.5-Inch speakers in this price range, the Polk Audio db650 had the most balance and organic sound. For whatever reason, these speakers always delivered or more “musical” tone. I listen to jazz, pop, R&B, classical, rock, etc, and these speakers seemed to have the best frequency response. Mids still are still not strong, but better than other 6.5s. The highs are clean and organic, not sharp and crisp like other speakers with metal tweeters. The bass is there, but since it’s a small 6.5 there isn’t a lot. You’ll need larger speakers to go along with these to make up for the bass.
The db650s sound very clear even when cranked up. At first, they were way too bright and shrill. However, now that they are broken in, they sound great. The pair has a pretty accurate response, I can’t detect much coloration on these, music sounds they way it should, no missing instruments. Really good sound at a reasonable price.

4-Channel Bridgeable Amplifier
The GM-6400F is one of Pioneer’s latest amplifiers (2009 model) and was designed to fit both cosmetically and technically with Pioneer subwoofers. The GM-6400F gives you total installation freedom and no distortion.
With an H-shaped chassis for vibration control and a PWM regulated power supply, you can drive multiple speaker channels or subwoofers and turn your in-car audio experience into the sound staging environment you’re looking for.
Review by E. Rodriguez, Miami
I installed this amp in my F-150 two weeks ago and wanted to test it out a bit before submitting my review and so far, I couldn’t be happier. My mids and highs are extremely clear now and I can actually hear small details in music that I couldn’t hear before with just my pioneer head unit powering my speakers. I’m using this amp together with a GM-5400t bridged powering a 10″ Kicker CVT and the systems sounds extremely clear even at high volumes with no distortion.
Being a relatively cheap amp, I wasn’t expecting much out of it but I’m truly impressed by it’s output and clarity. I also read that the previous version of this amp the GM-6300f had some overheating issues but I think they have been resolved with this model. I have two amps mounted behind my rear seat with barely any ventilation and neither of them have turned off once. I’m sure that there are better amps out there but in this price range, I can’t imagine one being better.
Review by Andrew R. Williams, Miami
Been in my car for a month or so now and sounds great. I have it hooked up to my 4 factory in-car speakers (98 Eclipse Infinity speakers) and they sound crystal clear and very loud. All my settings are set to default out of the box on the amp and the stereo is set for max highs and slightly below highest setting for mids. I don’t need to go higher on any of the gain values default is great on the amp. Although I’m not using this amp for any bass it sounds great if I do turn the bass level above 0 on my stereo (I have a separate amp for bass on a sub).
One thing I didnt like is the way the speaker out part is. They are ontop of each other but the rears extrude out further as if they where steps. It sticks out quite a bit and for some reason left and right are backwards so its right speaker and then left? Besides that its a great amp, looks nice to with the black and the red on the sides.

What people are saying…
The R.I.P.S makes all the difference when paired with the bass control this amp gives you. Almost no system will push an amp to its full potential due to lower than 14.4v to the amp. This amp doesn’t need that so the 500w is the real thing, makes my 12w6v2 sound great, if you want a JL sub make sure you have money for this amp as well. JL subs need the clean power that this delivers.
Mike, Iowa
I have this amp and a JL 12w6v2, and the combination is insane in my truck! I used to have a nice Alpine amp with the same rms rating and it didn’t sound half as good or was half as loud. I’ve never notice with other amps the difference in quality when you crank it up until I got this one. This is the best amp you can buy and it will make any sub sound a lot better. Plus Amazon.com has it for a steal.
Klein, New Hampshire
Very nice amp. I have this powering my JL 10w7 in my tahoe and it is simply amazing. The power coming from it is very clean and is always consistent. I would recommend that you buy the bass knob to get your “custom” listening preference.
Chamberlain, Charleston, SC
This is an absolutely awesome amplifier! The power and clarity are just fantastic! It says 500 rms, but in reality (as most in car audio know) it is pushing around 700+ rms. Unbelievable tuning capabilities. I purchased the remote bass knob which is an absolute godsend – comes in really handy when using an IPOD and you switch from bass heavy music to older music that has not been mixed as well. This amp is a little pricey, but you get what you pay for. I have run Alpine amps for around the past 10 years and decided to try something different. MO the JL amplifiers are in a totally different league. The sound quality is just phenomenal!
Negatives: Be really careful, the allen bolts that tighten down the speaker, power, and negative cables are made of really soft metal and will strip easily.

Type-R Series 12″ Subwoofer
There is not a single thing wrong with this sub. The sound quality is perfect and when you want it to, it will blow you away with smooth powerful bass. I have it wired to an alpine MRP-M650 amp and it sounds perfect. It’s actually better than the two twelves I had before. The best thing about this is the price, you can’t beat it. Trust me, I did a lot of shopping before I picked this one. I listen to a lot of rock, techno and some rap. This sub sounds great with it all. I highly recommend it. The bass is deep and is definitely clean. Don’t get me wrong, this thing does have the power to bring the apocalypse but that is why you can adjust your amp to your preference. Tyler – Detroit, MI
The Alpine Type-R. Where do I begin? I’ve been in the car audio scene before I could legally drive. I am now 30 years old and still enjoy it. Don’t get me wrong, there are a few subwoofers that outclass the Type-R in my opinion. The Kicker L7s and the JL Audio W7s, but for the price… they can’t be touched. I can’t believe someone would put these under Audiobahn. The Alpine Type-R will not fall apart, blow, or distort if matched with the proper amp and wired correctly. I was so impressed that now I am now curious if something for a $100 sounds so good, what do the Type-Xs sound like? Might have to buy a pair and find out. If you seriously want a great and powerful system for under a thousand dollars, go with the Type-R as your subs. Don’t cheap out and go Audiobahn, Lanzar, Soundstream, Sony, or any other cheaply priced and manufactured subs. Those subs are priced under 50 dollars for a reason. Elena M. Allen – Amazon.com

1-Channel Mono Subwoofer Amplifier
The Alpine MRP-M500 mono amplifier drives your subwoofer system with up to 500 watts RMS — enough to satisfy the hungriest bass setup. The low-pass filter puts you in command of the frequencies that reach your subs, while the variable bass boost is armed with plenty of low-end punch. A subsonic filter prevents wasted energy by eliminating ultra-low bass, putting all the power where you need it.
Preamp and speaker-level inputs allow you to connect this amp in almost any vehicle. Let a V-Power amplifier transform the sound of your car’s audio system.
Sample Reviews
I just recently had this installed in my blazer along with a Boston Acoustics G1 12″ sub in a sealed box. I am highly impressed with the amount of power this puts out and the fact that it’s black blends in perfectly with the color of my cargo area: much harder to see thru tinted windows. Mounted on the rear passenger cargo area, it was wasted space but not anymore. The only item that had me leaning toward the JL Audio Amp was a remote bass hookup, which the Alpine doesn’t have. My installer, wired one up with RCA Plugs, and I have never looked back. Would buy another in a heart beat. Great stuff at a great price.
buhusky2000, Scranton, PA
This is really where this little amp shines. Sound Quality with my single Pioneer 305DVC is great. The lows especially sound much better than my previous amp (Visonik V500HC). The punchy bass sounds a little less than my previous amp, but I was using 2 subs with that, as opposed to now. The fact that this amp with 1 sub, sounds nearly as good as my previous amp with 2 subs makes me very happy. It seems to be very efficient, barely dimming my lights (my fault for weak electrical) at full volume. For the money, it’s a great sounding amp.
