This is Rockford Fosgate 4080 car amplifier. amp has been tested and is in beautiful condition. Comes with both End Caps. This Amp has bass and treble gains. Amp will come overly packed. Amp does have some chips in the paint that were touched up. The last two pictures shows the two touched up areas. This Amp has the capability of running for12s crazy clean power nothing but the best from Rockford Fosgate. Says 40watts x 4 @ 4 ohms but it’s more like 100 watts RMS @ 4 ohms. I have the X-cards tuned perfectly at full range. Personally I think this 4080 amp is better than it’s brother the 400x4 because this amp has the bass gain on it. Really helps if you plan on driving subs with it. Please ask any questions. Fast shipping. Thanks for looking.
