Is your door sealed up well and are they mounted on a solid surface? Sounds like an installation issue tbh. If you're after a decent amp though I've got a Genesis profile 4 4 channel amp for sale. 4 x 75w or 2 x 140w bridged. Has filters so that it can run active, which means if you've got components 2 channels power tweeters and 2 the woofers.
