MB Quart DSC 4125

good amp no problems as of yet.

this amp is the best bang for the buck out right now. i paid 130 shipped off ebay. never runs hott and actually doesn't sound bad like most cheaper 4ch amps. You will not be unhappy. Amp is kinda long though.

This amp produces great, clean sound and at a great price.

MB Quart makes high end gear for car audio lovers in Germany- this is no exception. Great prices and tons of power coming out of this amp. For this kind of amp in say Alpine you should expect to pay more. As with any thing German. Make sure you ground your ground cables properly. I did and somehow it got loose from driving and I developed a buzzing engine noise in my front speakers. Retightened the ground cable and it fixed it. To the guy who is having the same problem...try that. If it doesnt fix it then move it to another spot for grounding. These amps need a strong ground because of the power it puts out. Once properly grounded it would close the ground loop.

I have just installed this in an 04 Impala(to replace a previous amp)! A premier 980bt headunit, and 6 1/2" infinity reference component sets in the doors and infinity reference 6x9's in the rear deck....alot of feedback...and no not engine noise! I had to ground the the rca's coming from the unit to stop the engine whine...but STILL has feedback! I had a GS redline performance amp, before someone else wanted it more than me(sum1 broke into my my babies when I was on vacation) never had this problem before with the feedback! Sounds great at high volumes with no distortion! Just cant understand the feedbak...any help would greatly help thanks!! :)
