It's rated at 4 X 250 into 2 ohms (in stereo, not bridged)...4 X 250 = 1000...I'm not going to bridge it, I'm going to run it in stereo...

Actually, I've got the print out of the bench test of this amp that did OVER 1000 watts...

Why, this amp will do 1000 watts...and cleanly...

Zero responses? Does anyone look at this site?

I have a 4 channel Alpine amp (MRV-F545) that I want to use to drive two 10s in a sealed enclosure. The amp can be configured to operate in 3 or 4 channel mode. Unfortunately, it can't be configures to operate in 2 channel mode. I'm looking at the E10 V.3 subs, but I'm not quite sure how much...

I haven't had this unit installed in a vehicle for quite some time and I'd like to install it now....problem is, I no longer have the wiring plug for the speaker outs (I always used the preamp outs before), and I don't think I have the mounting sleeve anymore (the one that mounts in the dash...

I didn't start this thread looking for a discussion about what's legal and what isn't (you're wrong by the way, loud systems violate noise ordinances). I'm looking for suggestions for a preamp that has either a headphone or line out jack, and a good set of headphones....let me worry about the...

Yes it is illegal, but no more so than driving down the street with the system turned up so loud they make the pictures in your house rattle...

I prefer wearing headphones in the car over listening to car speakers for several reasons. For one thing the phones cut out a lot of road noise inside the car, but the main reason I like them is because they just sound better than car speakers. You can hear every detail in the music and you get...

I have a dmm. What do I need to check and what should I be looking for?

I paid the guy to diagnose my problem. I'm assuming he checked the battery, alternator, and associated wiring. If he didn't do this, then how does he know the problem is being caused by the amp and not something on the car? I shouldn't have to go behind the guy and recheck everything he was...

I would assume the mechanic did that

'99 Corolla. It has the stock alternator rated for 80 amps. The amp is an Alpine FVR-545. I don't think that's what he meant. I believe he meant the amp is drawing more current than it should be for a given volume level. Could the amp's power supply be going and causing it to draw way more...

I took my car into the repair shop I use to have them check out the electrical system. My HU was shutting down on it's own, and the headlights were dimming to the point of looking like they would go almost completely off when the bass would hit, even at very moderate volume levels. I figured...

I sent them an email as they didn't have anything listed on their site for the Corolla.
