I have the stock 130N radio with serius. I don't have enough volume. I don't really want to change the head unit so is there an amp that I can install that doesn't involve cutting into the stock harness. I guess that I am looking for pretty much plug and play. Does it exist. Thanks

There are a couple of threads about a plug and play direct amp swap to replace the one under the dash. But your still limited in the signal coming from the HU. If you don't want to replace the HU, you can go with an Audio Control device as listed but then you have to re-tap into the speakers at some point - or go new speakers.
Really you should consider a new HU and all new speakers/amp. Just my opinion.
