...hmm, not sure why my Photobucket pics didn't post?

I think you will be quite happy when you try them. I had a feeling that a larger box would yield deeper extension, which, in my opinion, is always good, but I'm no expert by any means. I really have to buy the SPG-TR, it would be nice to have the proper radiator in that box, instead of the Sunfire. I think that the weight that's glued the Sunfire radiator is 3lbs, but don't quote me on that. It seems to do the trick though lol. I need to learn how to use my Umik mic that I bought several months ago, along with REW so that I can do some measurements, just to see how my sound 'looks'. Thanks for your input, let me know how you like them when you get them up and running.For what its worth I built my boxes with an internal volume of 1.3 cu ft (the factory recommendation is 1 cu ft). I used the SPG-TR (matched passive radiator) with the SPG-555. I'm not an expert but my understanding is that tuning of boxes with passive radiators is less critical than if using ported or sealed designs. Plus, the SPG-TR is tunable. I did ask the Boston Acoustics tech support team what they thought of the volume. They agreed that it might offer just a bit more low extension, with out resulting in loss of definition. I have not tried them yet, so I cant attest to to the result.
My apologies if I wasn't very clear..I knew I wasn't the only one using a car sub in my home setup, I've looked at a few threads here that are using them, I just meant the Boston SPG555 sub. When I started the thread, I was really hoping that somebody else had tried that particular sub, and that they could guide me or give me some good pointers to keep in mind, like maybe a a better size for a sealed enclosure that may go even deeper than it already does. I often thought about trying a 2 cu/ft box just to see.Hey Nitrofreakman, you're not the only one to use a car sub in your HT. I'm using a 12" Rockford Fosgate in a bandpass box. I'll be posting a build thread sometime in the near future, I will say that I made at least one big mistake building it and the knowledge I gained from reading others threads helped me realize what I did wrong and fix it.
Also it doesn't take a lot of tools build a sub.
It may not end up pretty, but it will sound good.
Well my friend, I want to thank you once again for all of your help! Today this arrived:Nitrofreakman...It was quite an effort to track the SPG-TR down...If you email me Ill forward all the emails, numbers and people who took over the Boston stock for the discontinued car audio division. Car audio tech support is in there. Just send an email or PM.
