OK this is the deal I have a 300 touring. I am running a pionner 4channel amp for my mids and highs, and a 2 channel punch500 to two 12's punch p2s(8ohm speakers-bridged down to 4ohm). The problem is my punch amp just cuts off. I think its just lack of power going to the amp. Also, after that cuts off, i can hear my mids and highs seem to lower in volume slowly. I would have to raise the volume higher that usual. Dash lights do dim alot. I have 4 gauge cable split to two 8 gauge cables using a distribution block to the amps. What do you experts think I should do? Would getting a farad capacitor do the job with what I have? Or would I have to get an optima battery as my 2nd battery. Or even more costly, will i have to upgrade my alternator and get either or a farad cap or battery. I thought this car would handle this extra stuff better than I experienced, cuz I had bigger systems in my old lil honda civic that handle this needed power better. I searched the audio forum here to decide, but didnt find an answer for my case. If any1 has suggestions, please feel free to help me out.

just a thought...if you have 2- 8ohm speakers bridged to 4ohm's and then you hook the amp up as a mono amp it dosent see 4ohms it see's 2ohm's<i think.. it might see 3ohm's<, because its in mono setting...so if iam right, the punch amp might not be stable at a 2/3ohm load..that would cause it to shut off to protect it self...just a thought...herbs

its a 2 channel amp, those amps are not 1 ohm stable, unless he is trying to run it at mono, which can cause the amp to over heat and cut off in 5 minutes or so

BINGO!!...thats what i was thinking he did...>?

2 single voice coil 8ohm subs will not read any lower than 4ohm wired in parralle.......but what do i know.......
if it wasnt briged it would be 8ohms stereo ....brige it and you have 4ohms mono...not 2 not 1

hey mexi,i understand the 2 -8ohms =4ohms....but if you have a 2 channel amp and you wire it in mono...iam 100% sure the amp no longer sees the 4ohm load..it will see a different ohm load because youve gone into mono..thus making more power thus blowing the fuse protector...
kinda like this lets say, 200watt in stereo and 400 watts in mono at 4ohms..
well if drop your ohms in mono, your 400watts will be 800watts at 2 ohms which is UNSTABLE for that amp..it weill cut off and re set it self..but like i said i know when you have 4 ohm load and you switch to one channel mono the amp is not going to see a 4ohm load..i wish someone with some exp chimes in...HEY WESS i need some help..
