I have a 2000 328Ci which currently has a non-HK system:

I'm thinking about this system:

1) aftermarket Amp
2) a/d/s 345is Separate Component Speakers for the fronts (or Dimaond Audio S500s)
3) 2 x JL Audio 8 inch Stealthbox Subwoofers that replace the 2 rear speakers
4) Peripheral Vendetta 4

I'm looking for a high quality 3 channel amp (or a 4-channel amp and bridge two of the channels for the sub).

Any recommendations?

thanks folks!

diamond audio 4 channel
a/d/s/ 4 channel
usamps 4 channel
alpine FIVE channel(more power than rated...ALOT more to the sub output)
brax
helix
macintosh
thats just to name a few....

thanks for the reply kevin7909!

which amp will give me the most bang for my buck? I'm trying to keep costs down.

usamps is by far the least expensive of the group and its a good amp...

For something a little less expensive: Pheonix Gold, JL Audio, Helix (as mentioned above)
