e2 ECAP1 by Scosche

This is the first cap that I have ever used in a car audio system, so not an expert. My system is 1264 watts rms total (600 for 4 speakers / 664 for subs). I hear less sub / bass dropout and harder hitting. I do notice that after driving a bit the lights on the cap all go out, but this is probably normal since who drives a car and watches the led. The build quality is very good (very heavy cap) and the price was great at Sonic. I would recommned this to someone wanting a good capacitor for a entry / mid level system.

I bought this item about a couple of months ago. Right now its hooked up to 2 alpine type R and kenwood amp. This cap stops my battery from dimming my headlights when I drive at night. I recommend it to anyone with a low watt system, around 500-100watt amp.

This cap is a good value. It is great looking and easy to install.

I've never used a capacitor before but I will definitely use them from now on. I bought it to try to fix my light dimming problem, which it did help a lot but not totally, but the difference in sound quality is amazing! It's powering my 4 channel and sub amp, 660 watts rms, and it's like a new system. Mids and highs are crisper and fuller and subs hit low and HARD now. A lot better then I ever thought 10w0v3's could. My buddy thought I got new subs and couldn't believe it was just bc of the capacitor. Highly recommended this product.

Good for how cheap it is, would be better if the pluggs werent so small
