Whats up guys/girls, I need a little assistance here. I at one point in time was running an MTX 8302 amp to my 2 10 inch MTX subs (T6104) in my old Cavalier, and had the JVC head unit supplying the power to the 2 front and 2 rear Infinity reference speakers. The subs are in a sealed Q Logic box with a partition on the inside seperating the 2 speakers.To make a long story short, I had to part with the 8302 and my Cavalier died, and I am now in the process of running those 2 MTX subs in my 1997 Kia Sephia (please hold laughter). I now have an MTX 421D amp and had a couple of questions.

1. Will the 421d amp have about the same level of power/quality of sound as the 8302 did?

2. What would be the best way to wire my subs to the amp? My subs are 4 ohms btw..

3. will the amp not kill my kia powered battery or should I go ahead now and get a capacitator to be safe

I appreciate any help you guys can give me. Thanks---

What are the power ratings on those amps?

Here is the manual for this amp. This amp will handle your subs better since its a class D sub amp but it shouldnt really be noticeably louder (just more efficient). Wire each subs plus and minus to the plus and minus on the amp and your amp will see a 2 ohm load. This amp should be ok for your car. This diagram shows how you should wire your subs:

the cap will kill your battery even more so. best way to get your battery from dying would be to 1. get a bigger bnattery.2 get a biggger alt. 3. both. a cap will do nothing but make your alt work that much hareder to keep juice in the car an supply the cap with power.

Thanks for the tips, I'll use the diagram you showed and probably just end up getting an Optima batter in place of the one I have now. Thanks again.
