ok its a 4,3,and 2 channel amp. its supposed to do liek 130 watt at 2 ohm brodged. i heard it was a radio shack amp. but it actually thumps that sub in my s-10 i told u guys about a while ago. but i think the specs are 85x4@ 2 ohms. and 100x4@ 4 ohms. that dont seem much but its bridgable so when u bridge it it has to be around 160 watt x2 ??? i know this amp cant be to great at all.

Ask Marc. He runs a few optimus amps. If I'm not mistaken optimus has been discontinued from RS. I wouldn't consider them trash.

sorry dude but those amps are junk. i used to work for RS and the comeback rate was way high and the RUMOR at RS was that they were made by pyramid.

decent amp. The number 1 reason they failed was from user error. After all, ppl who were buying amps from radio shack shows that they lack knowlege from the get go. They put out rated power. Also, Radio shack had them built for Radio shack at popular build houses in China. Other amps may have been built in the same house, but they were not relabel crap. They were original designs. One of the most common houses, was the same that made Sanyo amps. But if you compare guts to any other amp from the time, there is no similariteis.

the company rated the r.m.s. wattage at 10% T.H.D. ! ? that means playing clean it might do 45x4 or 135-145x2. he!! a dam 'vr3' walmart amp will do that good
