Here is the specs: 2 Channel 500 Watt Tantrum Amplifier Amplifier Type: 2-channel RMS Power: 125W x 2 Bridged RMS Power: 500W x 1 THD at Rated RMS Power: n/a Speaker Level Inputs: Yes Preamp Outputs: Yes Built-In Crossovers: HP/LP Bass Boost: 0-18 dB Frequency Response: 20-20,000 Hz Thermally Efficient Heatsink Timed Acoustically Integrated Muting (TAIM) Differential RCA or Speaker Level Inputs Tri-Linear Capability Allows Simultaneous Stereo and Bridged Operation 18dB / Octave High Pass or Low Pass Crossover 40Hz to 800Hz Continuously Variable Crossover Frequency Auxiliary Outputs Route Inverse Crossover Signals Variable Twin-"T" Bass EQ Circuit Provides Up to 18 dB of Boost at 45 Hz Optional RMD Remote Monitoring Display Port ---2 Ohms Bridged / 1 Ohm Stereo Stable
I dont understand these specs. I am used to seeing the power ratings at different ohms. What does the last spec mean? 1 ohm stable per channel? 2 ohm stable each channel? How much at 2 ohms per channel?
I think its 125wRMS x 2channels @ 4ohms. I heard these amps are underrated though, and some reviewers said they ran thier Alpine 12" Type R's with them. I am trying to decide if I should suggest this amp for my friend to buy at the pawn shop for $140 to run (2) 12" Type R's, which I read a review for it to be ok. I am just concerned it will not be enough power. Also wondering why they discontinued this model so soon, or if that should even be a concern in the car audio industry. Ultimately, will this be enough power for the R's?
Hey LouieV, from the reviews I heard, they're suppose to be pretty good. However, for some odd reason, no one's listing any spec at 2ohms nor 1ohm. That sounds fishy. I know the manufacturer listed 2ohms and 1ohm stereo stable, but even those guys aren't listing it. This holds true for most amps. If an amp offers 125W @ 4ohms, then at 2ohms, it is around 200-250W, and 400 - 500W @ 1ohm. I don't like manufacturers that do not list SN ratio, Damping factor, slew rate and THD @ full power. Zapco, older Orion and PPI amps list them. Without those numbers, it's not easy judging an amp. I have a Jensen amp that sounds great and can take all kinds of abuses. However, compared to higher end amps, you can hear the difference in sound quality.
Ok I just got this amp today, something happened in the process and I blew a raidio fuse which I replaced. However, my HU (Pioneer deh-25) is STILL NOT WORKING! I am trying to fix this problem now.
Does anyone know about these amps, or more importantly now, might lead me in the direction to get power to my head unit?!?!
