No.  It depends on many other factors than that.  Parallel connections only work if speed is throttled per connection, ie shared.
If wee assume the server isn't bogged down, and you're not using a "shared" connection, parallel connections will probably have no impact on speed, even if you're not maxing out your download speed limit.

Generally, for home connections, you should have little reason to use more than a few parallel connections.
