Where is this amp rack thread? I was planning on doing the same thing once I need more than one amp. For now I just mounted it on the side of the trunk like so:
Yeah yeah yeah I know it'll fall off eventually, but I'll have moved it before then.
Nice amp, I have the gta 504 4 channel amp running my interior speakers and an alpine MRP-M500 mono block amp running my flat kenwood 12 inch sub. I built an amprack that sits just beneath the rear deck.
