[QUOTE="unrealii, post: 932427, member: 554599"] I have an MTX Thunder 5400X 5 channel amplifier. It is almost 3 years old. It had failed 1 month after i installed it in my ford taurus. Last year I sold the taurus and now the mtx is in my maxima. I like the sq from the amp, but it is starting to fall appart. I am pretty sure these have always been bad, I just never needed to use these features when it was in my taurus. First, my cross overs are bad, I get high pitched noise from the high pass filter. Second, my sub woofer pulsates when I inititally turn the amp on or when there is no signal going to the sub channel. It also pulsates when I adjust the gain or if I press the knob side ways. I have a good guys warranty, I dont know if they are going to make me live without a car stereo for a while (ie ship it to the repair center in AZ) or let me use the $250 I spent on the amp towards another amp. Right now I have the following configuration: hu: Eclipse cd8454 speakers: polk audio, db6510, db5510, db3000 tweeters, 2 cross overs sub: image dynamics idq 10 Amp Configuration: -channels 1 & 2, provide power to the polk crossover which splits the signal to the tweeters (in the front) and 5.5" speakers in rear doors of the car. (using the cross over settings on my hu, I can turn off rear fill whenever I deem it necessary ;-) ) -channels 3 & 4 provide power to the front 6.5" speakers. -5 - directly to sub I really doubt good guys will let me use the $250 I spent on the mtx towards another amp, but I just looked on ebay and a 5400x just went for $180. Ofcourse I will sell it after it is repaired. Anywhoo, here are the options I am considering. I am looking at jl because I hear they are very well built and I am not in the mood to be taking my trunk appart. [B]1-keep the mtx...even if it means going for 2-3 weeks without audio[/B] [B]2-upgrade to jl audio 500/5 to run my entire system[/B] [B]3-upgrade to jl audio e6450 (I am running 6 speakers...why not give em a channel each?) & a mono class d amp (probably the e1400d)[/B] I know two amps are better than 1, but if I go with 2, then I will probably end up spending an extra $100 in wiring and mounting parts to mount these things.
