Boston G21244

[slovell 10+ year member]

I've been given a Boston G21244 dual 4 ohm voice coil sub that configures in either 2 ohms or 8 ohms. I have a Kenwood stereo amp that can be bridged to produce 300 watts mono at 4 ohms but is not 2 ohms stable that I use for a sub amp. Can I use this speaker with this amp? If I'm thinking correctly, this speaker will operate at 2 ohms when hooked up to this amp. Should I exchange it for the G2124 single voice coil 4 ohm unit? Should I get another G21244 and run a two speaker configuration even though I really don't want to run two subs? I'm kind of a noob and I would appreciate any advice I can get.

Thanks, Sam

The amp you have is probably only 4 ohm stable when bridged.

I would try and find a more powerful amp first.

You could get another g2 dvc4 and run both subs at 8ohms each to get a final load of 4ohms on the amp.

Or ditch the dvc4 you have now and just get a single 4 ohm and you'll be fine.

If you get 2 and run them together, you will be massively under powering them. Though they are pretty efficient speakers, make sure you dont try to get more output from them but setting the gain higher or jacking up the bassboost. This is the mistake a lot of people make when under powering their subs. Those subs have a 2.5in coil if Im not mistaken, they should be able to handle up to 600wrms of clean unclipped power, maybe a little more than that. I wired my G1 12-4 to an amp that was rated for 534wrms and it did fine and didn't get warm at all, I never measured box rise but Im pretty sure it was still getting at least 400wrms on the right notes. I love BA subs, they are really overlooked by everyone. My G5's are the most musical subs I have ever heard. They hit every note spot on from the mid 20s to the mid 70s. Everyone that has heard them has been really surprised.

Thanks for the advice. I decided to get a G2124 SVC 4 ohm and be done with it. You're right, my amp is 4 ohm stable when bridged and makes 300 watts at 14 volts. That's enough power for me, for the time being anyway.

Thanks again, Sam
