Alpine MRP-M2000 Amplifier Review

admin — Sun, 11 Apr 2010 05:09:06 +0000

The Alpine MRP M2000 is the most powerful Alpine amp ever made and boy is it nice. If the M500 and M1000 are not good enough for you then this is a serious amp that you need to look at. The MRP M2000 has the same style as the other Alpine MRP amps but it is much larger, so if space is a issue this might be something to keep in mind. The MRP M2000 has a MSRP of $750.00. Now we do have 2 wiring options to look at depending how much power you need and how our subwoofers are set up, at 4 ohms you have 1500W and at 2 ohms you have 2000W. The M2000 is a class D subwoofer amplifier, but I think you would have guessed by the way the out put is.

Alpine MRP-M1000 Amplifier Review

admin — Wed, 07 Apr 2010 20:38:43 +0000

The Alpine MRP-M1000 is the big brother of the MRP-M500. So if you like it but thought you needed more power the MRP-M1000 might be perfect for you. This car amp offers the large heat sinks for great cooling and power delivery like the other MRP amps by Alpine. The MRP-M1000 has a couple of wiring options. We can go 4 ohm and get 600W or if you need the full 1000W you have the 2 ohm option. With a MSRP of only $450.00 this could be a great deal for someone who’s subwoofers need some real power.

Alpine MRP-F300 Amplifier Review

admin — Wed, 07 Apr 2010 04:19:54 +0000

After look at the Alpine MRP-M500 yesterday I decided to talk a look at the Alpine MRP-F300. This is also a class D mono amplifier designed for powering our subwoofers but it is set up a little bit different. The Alpine MRP-F300 offers a few different wiring options. You have the 50W x 4 at 4 ohms, 75W x 4 at 2 ohms and bridged 4 ohms to delivered 150W x 2. The MRP-F300 has a MSRP of $230.00. As with all the MRP amps from Alpine you have the heat sinks and other cooling technology to keep this amp running cool and giver your subwoofers great clean power.

Alpine PDX 5 Amplifier Review

admin — Sat, 27 Mar 2010 19:54:27 +0000

The Alpine PDX 5 is a great choice if you are only looking to buy only one car amp. This is a 5 channel that offers 75 watts 4 ways to your car speakers and 300 watts of power your subwoofer. Now this is not the choice for you if you are looking for a very load car stereo system, but its perfect for the average person. With a MSRP of only $650.00 this is a cheap way to power 4 mid range speakers and or highs and a subwoofer. Depending on your systems wiring this amp may also give your more wiring options with its ability to put out the same power at both 2 and 4 ohms. The Alpine PDX-5 has to be one of my favorite amps of all times. The PDX-5 also has the stackable design of the PDX series. This amplifier is also very easy to setup with all the terminals on one side. I have installed the PDX-5 more than a few times and have always been happy with the results. Let me know what you thing of the amp.

Alpine SWR-1242D SWR-1222D New Type R 12″ Subwoofers

admin — Thu, 28 Jun 2007 02:39:59 +0000

Alpine car subwoofer reviews. Alpine new type R subwoofers are really something to listen too. I was with my cousin Eric picking out new subwoofers for his car at a local car audio shop and he decided to listen to two 12″ Alpine SWR 1222D’s in a ported box. The bass that was coming out of the enclosure was incredible. He could not wait to get them in his car to see how they sounded. We went to his house and set them up in his car and he was very impressed with the bass he got of out these two 12″ subwoofers.

Now the Alpine SWR 12″ subwoofer come two different ways. The SWR 1222D is a dual voice coil and is 2 ohms and the SWR 1242D is dual voice and is 4 ohms. Both of these subs can hold 500 watts RMS and 1500 Peak watts, so they are capable of putting out some serious bass. The only different between these two subs other than the ohms is that the 122D can play a frequency of 23hz-500hz and the 1242D a frequency of 25hz-500hz.

Alpine is always keeping up with the times. Just recently Alpine-USA have updated there website for the Spanish community. Not just a little bit of the website is in Spanish the entire website is. This is great news for the Spanish speaking community. You can now read all the product name features and do product comparison all in Spanish. Alpine also has it set up so that all the information about the alpine custom car audio cars is in Spanish. This will be a great time to sit back and wait to see how many other car audio websites will follow suit with the change that alpine has made. If you would like to check out the new Spanish version of the site you can look at it here.

Alpine SPX-107R 4″ Speaker Review

admin — Thu, 21 Jun 2007 20:27:22 +0000

Alpine car speaker reviews. A friend of mine came to me recently about getting some 4″ speakers for her car. Price was not really a option for him he just wanted to get a loud pair of component speakers. Of course my first suggestion was to cut out the door panels to either 5-1/4 or 6-1/4 but he did not want to make the modification to his car. So we went to our local car audio dealer to look around and listen to a few of the 4″ speakers. He set his eyes on the Alpine SPX-107R’s. I was not to surprised because he is a big alpine fanatic.

After listening to the speakers for a little while i was surprised at the sound they could put out. Now keep in mind they are now the loudest component speakers but considering that they were only 4″ i was really impressed.

Just a couple of things to keep in mind if you are considering getting these speakers for your self. The RMS rating is only 40 watts, so watch how much power you are putting to them so you don’t plow the speakers. The 1″ tweeter does produce very nice highs considering the low RMS. The down side to this speaker is definitely the lack of mid bass, but that could be expected from the Alpine SPX-107R’s 4″ driver. If this would have been my car i would have cut out the door panels to take a larger speaker, but if you are looking for a 4″ component set definitly look in to the Alpine SPX-107R 4″ Component Speakers System.

Alpine PDX 4.100 VS Alpine PDX 2.150

admin — Fri, 08 Jun 2007 20:54:57 +0000

Alpine car amplifier reviews. After my resent port on the Apline PDX 4.150 I decided to go ahead and do a review of the PDX 4.100 and PDX 2.150. The whole Alpine PDX line comes with the really nice stackable design. The differences between the amps should be obvious. The PDX 4.100 has the 4/3/2 channel option but come with 100w x 4 at 4Ω. The PDX 2.150 is the only one of the three to have a one channel option. The amplifier come in the 2/1 channel option and has 150w x 2 at 4Ω.

Other than that and price the amplifiers are the same. The PDX4.150 price is 750.00, PDX4.100 price is 550.00 and the PDX 2.150 is at 450.00. These prices come off of Alpine’s webiste and your local dealer may be different.
