Bought this amp two weeks ago and installed in one day. Running four FSX-65s and four SPX-T 1” tweeters. Two of each per door. They sound mad clean and LOUD! By all means I was impressed and that takes a lot. I’ll be a returning customer
Clean with lots of power
Got this on front and rear set of ds-18s 6.5s and horn drivers and its loud enough that it hurts. Only thing was that the screws in the end of the amp came out then it started making a crackling noise in the speakers. Sending it back to skar for repair or replacement. Hope it all goes well.
One week in.
So far so good, only using 2 channels atm but its been pretty solid no issues yet.
It’s About To Get LOUD
A little project I’m working on. Original 1970 Monte Carlo SS 454 equipped with nothing but SKAR AUDIO, down to the speaker wire. Will be adding another amp for the VX4-ST’s and of coarse a bass package.
