amps getting hot

JP - AGMs use as you describe are totally cool. At first I was thinking "what spills" - but mine are semi-sealed (unlike the old capped ones that used to wreck my chrome every time I dropped my bike) without leaks - not that I have inverted them or had them tipped over for long. My anti-AGM comments are for audio buffs that get them for their low ESR (or internal resistance), but instead of mounting next to or near the amps, they mount them in the engine bay which usually defeats much of that purpose (path resistance (and inductance?) from batt+ to amp and then back via GND). Add to that, wasting an AGM with engine starting when normal batteries may tolerate it better... Granted that for audio, an AGM is better than a wet cell, but all that for a 10 milli-Ohm gain or less? IMO the best is an AGM near the amps, and normal battery for the engine. Hence can concentrate on low resistance between the AGM & amp (with arguably less critical alternator/battery to AGM depending on alternator and amp capacities etc.)     The cap argument is straight forward. You may need a cap if the amp is far from its low-impedance power source. But even a small AGM battery will usually outperform cap of several Farads. So why not a $20 1.2AH or $35 7AH AGM next to the amp instead? Arguably paralleling batteries has issues, but so too does charging a BIG discharged cap. And either cap or AGM can drag down and ruin the prime battery - though that is far more likely with the AGM. In short - ignoring parallel battery issues - an cheaper AGM battery or similar will outperform a cap (for dips; and both are likely to result in lower SPL). (And if the AGM is big enough - say (maybe 7AH else) 15AH or bigger, it's a handy emergence cranking battery.) But you'll find heaps of posts & refs on that... (sales people included).

Looks like 6061-t6 (the state of the alloy I used) has 40% + conductivity. It doesn't seem terrible. Any other suggestions on possible causes? The amps really can get hot when the volume is up. Just below to hot to touch and just above to hot to hold. Thanks for all the Help BTW!The ass of my art form is always exposed
