I have the Bazooka CSA150.1 250 watt amp and a Lanzar 250 RMS/500 watt peak. i can turn my truck on to acc. and the sub will work but when i turn my truck on, the sub will be hitting for only a couple of minutes, then the amp will turn off. But after that, you can turn the truck back on acc. and the amp will run great... what could be causing this? Thank, Bryant

Re: amp turns off after a couple minutes of playing
That's a new one on me. The only electrical difference is the battery voltage on ACC is 12 volts. When you start the truck the alternator should put out about 13.7 volts. That would make me suspect a bad power supply in the amp or the output transistors, something in the amp is getting hot at the higher voltage and shutting it down
That would explain why you get two minutes ,and than when you turn the truck off the voltage drops back to 12 volts and the amp comes out of protect mode. Try a amp swap or if it's a self amplified tube, hook it up to a friends system.
Never hurts to put a voltmeter on the battery with the truck running, and off, to make sure the alternators voltage regulator is not faulty and exceeding the rated voltage. Good luck, let me know what happens, I'll ad it to the book. Regards Paul

Considering what they are you should be fine, just make sure you do not use the bass boost and you have your gain turned all the way down adjust your gain from there you should not be using any type of bass boost through your head unit, basically you want to start with the least amount of power your amp can put out before you hit the max out so you don't hurt your speakers be sure to listen for clipping or bottoming out
Speakers are rated either at RMS (root mean square) average power or Peak Power. An RMS of about 125 watt is equivalent to 250 watt peak. To match the radio and speakers they both need to be consistent. Also do not be confused with total radio power out vs per channel.
So if the speakers are 250 watt peak power then a radio with 125 watt per channel or 250 watt peak per channel would be a good match.
If the speakers are RMS 250 watt then the radio would be 250 RMS/channel and usually with a four channel radio a total of 1000W RMS
With that much power the neighbors should hear you coming!
I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!
This is an 150 RMS amp, but the ratings say it'll push 2 10's. You probably won't get much out of that amp with a 1230 watt subwoofer. The subwoofer you are wanting to run is 300 RMS, so you'll get half the power you could be pulling. But it would do okay I guess. Nothing like what you could get with a different amp though. You need like a 1000 watt amp to get the most out of your sub. But "YES" you can use them together.
Amps can be rated based on their RMS power or their peak power. In this case, the amp's rated RMS power is 300x2 at 2 ohms (total 600W RMS) with a peak power rating of 600x2 (1200W peak). For the most part, peak power means almost nothing.
If your head unit didn't have RCA preamp outputs, you would used the standard speaker outputs from the head unit and connect them to the hi input plug of the amp.
While I don't have any first-hand experience with either Bazooka amps or Memphis subs, this review pretty much says what I initial thoughts were. The amp will do the job without much fuss, so it mainly depends on whether you can get it for a good price. BUT........ There could be a issue with your sub. According to Memphis, your sub (assuming it's the single voice coil version) is only good for about 250W RMS (let's ignore peak power for now). The ELA500.1, on the other hand, puts out 375W RMS at 4 ohms. You could very easily overpower your sub with that amp.
The advertised wattage for your amp is:
300 watts RMS X 2 @ 4 ohms
600 watts RMS X 2 @ 2 ohms
The actual wattage you will be using will depend on what type/impedence speakers you are using, and how they are wired. Here's a link to some more of the specs of your amp: http://www.bazooka.com/productAutoAmplifiersRS.asp?id=199
I hope this helps.
