My yellow tops were starting to get weak again, so we just swapped in this bad boy (SP2150A) yersterday. Fits like a champ and has almost as much reserve power as 3 yellow tops. This is their new (allegedly) super industrial design so we'll see how it holds up.

I wonder if you had constant draw from your stereo and it was killing your batts. I know a guy that can wire it the proper way for you.
