A GREAT Accessory ..... Siriusly! 
2007-06-27
I am so glad we bought this accessory for our portable Sirius receiver. GREAT sound. Unmatched convenience. GREAT reception.
Does What It Does 2007-05-02
Works fine with my Starmate 4 as a boombox. Very light, looks nice.
IMPORTANT HINT: I would recommend you DO NOT use the antenna that comes with the boombox. I did and thought I wasn't going to be able to have Sirius because I got no reception (3 bars on the terrestrial signal, none on the satellite) in my apartment. Fortunately I read online someone had a similar problem and they switched to the magnetic car antenna (it will attach to the boombox). I did the same and my reception problems were solved (both satellite and terrestrial signals are nearly full on the reception indicator). Again, use the car antenna (provided with whichever receiver you buy) NOT the boombox indoor/outdoor antenna.

Bought as a gift for spouse. It works pretty much as expected; plenty of channels, I tend to stick with a few familiar voices. It is hard to find a good location for the antenna to ensure signal strength. I have not tried the 'booster cable' or preamplifiers. resent having to buy more stuff - it should work.
Otherwise no complaints. Have not tried the car kit though its supposed to be usable out of the box.
Great Portable Sound System 
2007-02-05
I have been using this unit with a Sportster 4 for about two weeks now, and this is the one item that has really allowed me to enjoy Sirius at home. I also have a home kit hooked to my stereo, but this item allows me to bring Sirius to my basement workshop and to my home office. These are normally pretty tough locations to get a signal, but as long as I have the antenna somewhere close to a window I can get a signal, even in these tough locations. My area does have a repeater that allows this to be possible. I think the Sirius signal is a little tougher to pick up than the XM signal (I am in the process of switching to Sirius), but this boombox does as good or better than the home kit. It even works with an XM antenna!
As far as sound goes, it is better than any portable solution that I have found for either service provider. The built in subwoofer makes a LOT of difference. It sounds good cranked fairly loud, and also sounds good at low volume, which is something that can't be said of the SA10002 XM boombox (I tried that one and returned it the same day - what junk!).
One other thing to note. I use this unit almost exclusively on batteries. It works great, but don't believe the battery indicator. The "power" light turns red, telling you to change the batteries. It indicated low batteries pretty quickly, but they had plenty of life left according to my separate battery tester (Radio Shack 22-096 - highly recommended). I have been using "low" batteries for about 8 hours and the batteries still test good.
Enjoy - I hope this helps...
Pleased with the sound, but what about the FM Transmitter??? 2007-01-30
I purchased this item two weeks ago. I have a pretty keen ear for music and was pleasantly surprised with the quality of the sound coming out of this box! Yes it lacks an equalizer, but at least the sound is balanced and I do not perceive any distortion when I crank up the volume.
My frustration, however, is that I have attached a Starmate-4 receiver and yet I am unable to obtain FM Transmitter information!?! It does not appear on the menu, nor does it appear when I press the dedicated FM Transmitter button. Supposedly, IF I can select an FM Frequency, I can tune my other home radios to the same frequency and listen to SIRIUS throughout the house! What a nice feature THAT would be!
After 4 calls to SIRIUS, 3 emails and a trip to a local electornics store, I can still not get an answer to my question, which IS: does the boombox HAVE FM Transmitter capability? or is my receiver broken? If anyone on here has a boom box and can answer this question for me I would greatly appreciate it.
Does return email or calls

I love this item. It has great sound and have used it everyday without problem. I would definately recomend this item.
Excellent Sound For The Price! 2006-10-22
GREAT BOOMBOX FOR THE SIZE & PRICE! It has a great sound with some decent bass. It's perfect for having around the home and/or office. Portable enough to take with you to the beach etc. One drawback we found was that the SUBX1 doesn't have an equalizer. But that's nothing compared to what you DO get! For the price, you cannot beat this boombox!
