ok so i need some advise here. i just got finished replacing my sub with an alpine type r slim and its great. now i have another small problem. after a while of continuous play at my determined maximum volume the amp driving my speakers is very hot, it actually hurts to hold my hand there more than 6 seconds i don't see any ill effects in performance due to the heat (except maybe my next problem) so is this ok? also while playing at this volume level i notice my passenger tweeter is making a rattling/popping sound when hard bass notes are hit, at first i thought it was door panel rattle but its defiantly coming from the tweeter, and this problem occurs ONLY when the sub is playing if i turn the sub off at the deck it disappears.

here is my system:
front speakers are energy (not shure of model) 5.25 components rated 100watts MAX (not rms)
powered by alpine v-power mrp-f300 bridged out to 150w RMS each (i know its over the MAX but they have taken it for 4 solid months)

rear speakers are deck powered

sub is alpine type r slim
powered by jbl 601.1 @4 ohm 424rms

How low does your voltage drop during bass notes? What kind/how old is the battery/alternator? Low voltage can lead to premature distortion out of amplifier. Make sure power/ground connections are clean and secure.

Excess power to the front components coils could have caused overheat issues within the component set over time and done damage. Tweeter VCs can be damaged pretty quickly and permanently.

Turn down gains to speaker amp and test voltage during burps. See if that helps and get back to us.

^ All good advice.

6seconds isn't too bad. Less than 2 seconds is closer to the limit, which is about 180F for most amps to shut off.

Clean and tighten all your power connections and you may want to consider the age and size of your battery. This is one of those situations where a power capacitor may help as well - try to borrow one off a buddy to try.

The tweeter popping while bass notes hit is due to modulation of your bass amp transfering to your speaker amp due to being grounded in the sae spot. Try grounding bass amp to a different grounding point and the problem should disappear
Any other speaker distortion would probably be due low power handling of your front speakers (100 watt max - probably only 50wrms).

ok so its been a little while but i finally found time to tinker, my voltage never goes lower than 14.42 volts and battery is brand new. i am also running a power capacitor, however its is VERY old and im not shure if it is working that great. i turned my gains down significantly and grounded my sub amp and speaker amp in different locations (the grounding points are about 3 inches from each other and on the same piece of steel)
BUT i STILL have the exact same problem. could this be deck related problems?

UPDATE:

i fixed it!! i decided to look at the manual for my amp and it said to set the filters to high pass for a set of tweeters and midranges. i was running them on full range because i figured the crossover was already in the component set. works good now though however my midwoofers dont get as much low notes anymore

sure is the word your looking for, makes me look like an *** but you used it in two different posts and I wanted to make sure you catch it in the future (eg work emails lol)

Sounds like u were running into distortion from your speaker amp. No idea why the rattling/popping would go away if u shut the sub off at the deck though.
