    Cheapish Mono Amp

    My roomate got a box with 3 Audiobahn 10s in it (I know, I know, audiobahn isn't the greatest, but it's a sweet box). Model # ABP103T (I think).

    Here's a link:



    I think it's actually an older model because it doens't have the etching on the plexiglass. Says it can handle 900W RMS.

    What kind of amp should he be looking for? He doesn't want to rattle his whole car apart, he already has an 8-speaker 'preimium' factory system that sounds decent.

    Something not expensive, and it can be mono since the box is pre-wired.

    How much money is in his budget. A JBL 600.1 amp is a nice amp for $350. Rider may have a class AB amp for sale too if he hasn't sold it yet.

      With a final impedance of 4 ohms, that JBL 600.1 will only put out 300 watts to the setup - not so hot.

      I'd step up to at least the JBL 1200.1. It'll give 600 reliable watts, and can be found for $250 - $300 online.

        I have to disagree with you on the Audiobahn equipment. There products not only look better than most, but sound awesome. And one thing I like about them the most is that they rate there amps at the RMS output, not the peek like everyone else does. So a 800 watt Audiobahn A8000T is putting out an actual 800 watts RMS, the total peek output WAY higher. Of corse, since my tunes are exclusive Kenwood and Audiobahn I may be a little partial.
        I got my Audiobahn A8000T mono amp from www.ikesound.com for under $200 bucks, and my A6004T 4 channel for under $200 as well.

          don't worry about rattling the car apart, except in the bandpass range. the subs are basically their lowest subs with different voice coils, so the subs are 12 ohms each, getting the 4 ohm mono load. they've got tiny magnets, and i'm going to assume really low excursion, so they won't put out much low bass. the general rule for audiobahn is take whatever they tell you for power, and divide by 2 so since it's rated at 900 watts, it's not a good idea to go over 600. especially with the woofers they use. also, bandpass is extremely hard on subs, so IMHO if you give them full power, they would likely fry quickly. you'll need to get an amp that is rated 600 watts at 4 ohm mono. lanzars are some of the few that will do that for a decent price, since most sub amps are designed to run at 2 or 1 ohm. this amp will work well. it's probably going to put out a little over 600 watts at 4 ohm mono rms. it can be purchased here. i figure your roomate will probably want to save some money, if he just spent $530 on that setup god what i could have done for $500 this is another good choice for amps, since it's the higher vibe series. you can get it here.

            Thanks for the replies... Actually he bought it from a friend for $175

            I'll show him the thread and see what he thinks. Thanks again, guys

            Oh yea, Network13, most good amp manufacturers don't quote peak wattage.

              thank god:p: i was worried he paid the $530 and yeah, very few decent manufacturers even tell the peak wattage anymore. audiobahn used to push the peak #'s like crazy back in the day. and peak output means nothing. that's the WLS rating. when lightning strikes and since there is not a standard for how amps are measured, manufacturers can lie out thier asses that's another reason for testing an amp. it can be done with a basic multimeter that can read AC voltage and resistance. you'll only be able to calculate it at a specific freq, though. play a sine wave through your system at full volume. measure the AC voltage and the resistance. then square the voltage and divide by resistance. watts = (v^2)/R course most amps are rated at 1000 hz, if they are capable of it. i've even heard that some bypass the filters so they can test it at 1000 hz, rather than the usable range of under 200 hz from a class D it's a way for companies like rockwood and boss to publish a 3000 watt max amp that really only puts out 600 watts

                Well - speaking of which - have ya' seen the new mono-channel, FULL-RANGE class D amps from Xtant?

                They're designed to be used in pairs, for regular component speakers.

                I can't remember how many watts they put out, but I know they list for about $350 EACH. Yikes.

                I think it was CA&E magazine that gave them a great review - said there was no measureable or audible difference between this new full-range class D and a typical A/B amp, and of course they are far more efficient.
                ................................

                I still think this guy will get the best bang-for-buck with a JBL 1200.1. I run the Lanzar Vibe amps (Viberant line), and while I'm happy with them, I wouldn't mind a more beefy sub amp. They are better suited for regular speaker duty, IMHO, due to the large power requirements of subs.

                  no, i haven't seen those amps yet do you know if they use the class X or T technology? i know the class T amps use a tri-path chip, but many still consider them to be class D amps, just with full range capabilities class X i don't know anything about, though.

                  the JBL is a great choice, especially since it won't be running at full power, so it won't heat up much, and it'll last longer not to mention if he choses to upgrade subs later, the JBL is capable of putting out a lot more power:p:
