I have a 300 watt alpine 4 channel amp powering 4 x 6.5" kenwood speakers. My speakers can take up to 170 watts each. I have to turn my gain up all the way on my amp in order to get a quality bass...


Your amp is overheating as your speakers all combined are 680 watts, double your max output on your amp. Ideally you need a 1000 watt amp to do the job and for perfect sound as you should never have your amp up to max as it is more likely to blow quicker. The 2000 watt amp your are speaking of will do the job perfect, but you need to keep the gain down around 50% as you could blow your speakers. But yeah all together you are right, the 2000 watt amp will stay cool as doesnt have to work nowhere near as hard as the one you have currently.

2 12" subs + 600W amp. Turn on, goes boom once, then red light


Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

I just got a sony xplod 1000 watt amp i got everything hooked up and when i turned the key the power light chaned from green to red. i check over the amp again and again, i cant find any thing wrong........


Try disconecting all speakers from the amp, turn it on after and if it stays on red it sounds like it had kicked the bucket. if it stays green start from their and check all of your wires for shorts (speaker wires) again. hope this helps...

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

I have one 12inch 1000 watt mtx sub what size amp should i buy


Hello taona80,

If the 1,000 watts is RMS, I'd recommend an amp in the 750-1,000 watt RMS range, perhaps like the Alpine MRP-M1000 or Rockford-Fosgate T1000bd. If the 1,000 watts is peak power, the subs continuous (RMS) power handling is much lower, probably 300-400 watts. In that case, I'd recommend the Alpine MRP-M500 or Rockford-Fosgate T500-1bd.

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

Mrv1507 power light blinks red..


Your speakers probably are made for 6 or 8 ohms. to check, take out any of the speakers and read the back for the ohm rating, if it is more ohms, you need a more powerful amp.

Make sure you don't have a short circuit somewhere. Make sure the wiring is all intact.

Alpine amp and subs questions


it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation
