Review: I have this amp powering 3 component speakers up front and 2 way speakers in the rear of my '98 Jag, coupled with a Kenwood Excelon 2 channel amp for my 10" pioneer shallow mount subwoofer absolutely amazing! All speakers except for subwoofer are Infinity Kappas. I'm hearing sounds I never heard before like the guitarist sliding his fingers along the strings.
Review: Looks good despite being under my drivers seat. Quality connection ports. Have 4 x 6.5" 150w capable speakers and two spliced component tweeters. Sounds great. Amp is 75w x 4 and sounds loud at anything over 22 on the volume dial. 30 is too loud (still clear). Speakers are Sound stage, head is Kenwood KDC-X704 Excelon.

Amp would turn off randomly I thought I had a bad ground but it was just random. I bought a new amp and will be sending this back. The box had no seal either. The box also looked old it made me feel that the amp might not be new. It’s not a power issue either I monitored voltage 14.4 the whole time and my second amp that powers the subs stayed on.
