Nevertheless DSP features would be nice to add! - The amp was installed matched with the front and rear VW IS 180 and IC 165 in a TIGUAN, it works just flawless. Nevertheless the price I consider too high for what offers. There is other options in the market for $100 less but with DSP features, like Kicker. I purchased as it was at discount from $399 to $270, otherwise I would not be purchased. The high input is very sensitive so if using it keep gains like in a 1/4. I would suggest to use line level inputs as you can get a better control. The size is just perfect, it fits at any space so it can be hidden if you want. Review: Focal Verstärker plug and play - Kaufempfehlung. - War selten so zufrieden mit einem Kauf. Er verstärkt die Angelegenheit, verschafft dem NewBeetle zusammen mit den Focal-2-Wege-Lautsprechern rundum einen guten Klang. Sicher nicht High-End, aber alles klingt sehr gut, der Schalldruck ist absolut asureichen, um den Schwatzkopp auf dem Beifahrersitz nicht mehr zu hören - alles so, wie es sein soll. 4 Lautsprecher - ca. 400-450 Euro, plus Kabelbaum, ca. 100 Euro, plus diesen Verstärker, ca 220-230 Euro, und schon hat man wirklich guten Klang im Fahrzeug. Nach 20 Jahren und mit einem Billigradio, kaputten Lautsprechern war es eine Qual. So ist das halt, wenn man ein gebrauchtes Auto kauft. Dieses Set mit dem hier gezeigten Verstärker war einer der besten Käufe in meinem Leben. ## Features - Far more powerful than a head unit - Easy integration within the dashboard - Compatible with all head units - Extremely versatile - Optional ISO connector for semi “Plug&Play” set-ups ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01EZYWW5M | | Best Sellers Rank | #302,670 in Electronics ( See Top 100 in Electronics ) #741 in Car Multichannel Amplifiers | | Brand | Focal | | Brand Name | Focal | | Customer Reviews | 4.5 out of 5 stars 101 Reviews | | Included Components | IMPULSE4.320 | | Item Dimensions | 9.75 x 15.25 x 17 inches | | Item Weight | 454 Grams | | Item dimensions L x W x H | 9.75 x 15.25 x 17 inches | | Manufacturer | Focal | | Material Type | Plastic, Metal | | Model | IMPULSE4.320 | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Output Power | 55 Watts | | Package Type Name | box | | Part Number | IMPULSE4.320 | | Specification Met | Iso,oem | | Unit Count | 1.0 Count | | Warranty Description | 2-Year Manufacturer Warranty | ## Product Details - **Brand:** Focal - **Manufacturer:** Focal - **Mounting Type:** Surface Mount - **Number of Channels:** 4 - **Output Power:** 55 Watts ## Images ![Focal IMPULSE4.320 Ultra Compact 4/3/2-Channel Amplifier - Image 1](https://m.media-amazon.com/images/I/51sBpqWTu0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is FOCAL quality!
