Im assumin the instllation was done good because it was installed at a professional audio place (dashworks) known for high quality audio installations

Haven't seen this asked yet, but where do you have the gain set at? I know that sounds so stupid, but I've worked in install bays before and that tends to be one of the most common reasons for this...just turn it down a notch, usually does the trick.

I still cannot tell if the subs are wired in parallel or series. It depends on how the wires are run between the amp and the subs itself. If they're "daisy-chained" together, then it's in series and you're running a total impedance of 8 ohms, which should be fine. If they're wired in a separate manner, then it's in parallel, which should give you a total impedance of 2 ohms...that would be your problem if your amp is not stable at 2 ohms.

Hope this helps somewhat.

if it was done at a pro shop, i hope the wiring is done correctly.

why dont you bring it back to that shop?

the pro shop said i need a fan for the subs because they are overheating and they turn off when they are overheated as a safety precaution

for the amp you mean.....?

is the amp mounted right? are the heatsinks mounted so that they dispruse(sp) the hot air from the amp?

is there enough room for the amp to ventilate?

will, thas a good idea, didnt really think about that. Its a really big box and the amp is mounted on the back seat. the cargo space is quite small as well. its a 95 vw golf. the box fits but the space is somewhat tight. im gonna try folding the seat back, maybe more ventilation will occur

cheese this is also a good idea because the gain is set at full? culd this be one of the reasons. by decreasing the gain, does it decrease the sound drastically?

By decreasing the gain a tad (say 75% as opposed to 100%), you will barely even notice a difference in sound. In fact, you will be pushing the amp less, which will not only reduce the heat (and protection systems engaging), but the sound level difference will be minimal. I won't get into the electrical/acoustics info unless you want me to go on about how the whole system works...just take my word on it. I'm a sound/acoustical engineer.

right now i have the seat back and the gain at about 75% and so far no overheating but the amp is still getting hot. if you touch it, it might hurt a bit. it hasnt cut out though. is this normal?

thanks

maybe its just an old amp.

i drove 1.5 hours just pounding both of my amps....after the drive i can still keep my hands on either amp for about 2 secs.

this is in 80ish degree weather in a sedan trunk.

good luck with it.

personally i think you should go back to the sound shop you got them from. as soon as they tell you that you need a fan tell the guy that the amp shouldn't be heating up like that in the first place to warrant getting a fan. i know for a fact that phoenix gold amps are not supposed to get hot at all. if the guy gives you any lip as to speak to his manager. basically the bigger an asshole you are the more likely they'll fix your **** just to get you out of the store. people complaining about poor service with customers around is bad for business.
